Topic: China vigorously introduces overseas high-level talents.

　　Qian Xuesen is a modern scientist in China, a world-famous rocket expert, an expert in engineering cybernetics in China, a system engineering expert and a system science thinker. A native of Hangzhou, Zhejiang Province, was born in Shanghai on December 11th, 1911. He graduated from Jiaotong University in 1934, went to study at Massachusetts Institute of Technology in 1935, got a master’s degree the following year, and then transferred to California Institute of Technology for further study under the guidance of tutor T.von Carmen. After receiving his doctorate in 1938, he stayed in school to teach and engaged in rocket and missile research. From 1947 to 1955, he was a professor at MIT and California Institute of Technology. After returning to China in 1955, he served as a member of the Aviation Committee, vice president and dean of the Fifth Research Institute of the Ministry of National Defense, president of the China Academy of Space Technology, vice minister of the Seventh Ministry of Machinery Industry, deputy director of the National Defense Science and Technology Committee, and deputy director of the Science and Technology Committee of the National Defense Science, Technology and Industry Committee. Joined the Communist Party of China (CPC) in 1959. In 1991, he served as honorary chairman of China Association for Science and Technology.

　　Qian Xuesen’s monographs include Engineering Cybernetics, Lectures on Physical Mechanics, Introduction to Interstellar Navigation and On System Engineering. More than 50 of his academic papers have been published in American journals and more in domestic journals. Qian Xuesen is a member of the Department of Mathematical Physics of China Academy of Sciences, honorary chairman of China Aerospace Society and vice chairman of China Association for Science and Technology.

　　Qian Xuesen served as the technical leader of China’s rocket and space program for a long time, and made great and pioneering contributions to space technology, system science and system engineering.

　　1. Applied mechanics

　　Qian Xuesen has done pioneering work in aerodynamics and solid mechanics of applied mechanics.

　　With feng? Carmen’s cooperative research on compressible boundary layer reveals some temperature changes in this field and establishes Carmen-Qian Xuesen method. In cooperation with Guo Yonghuai, the concept of upper and lower critical Mach numbers was first introduced into transonic flow.

　　2. Jet Propulsion and Space Technology

　　From the 1940s to the early 1960s, Qian Xuesen put forward some important concepts in the field of rockets and aerospace: in the 1940s, he put forward and realized the rocket-assisted takeoff device (JATO), which shortened the runway distance; In 1949, the concept of rocket passenger plane and the idea of nuclear rocket were put forward. In 1953, the possibility of interplanetary flight theory was studied; In the Introduction to Interstellar Navigation published in 1962, the concept of a round-trip transportation system between heaven and earth was put forward, in which a large plane with a jet engine was used as the first-stage vehicle and an aircraft with a rocket engine was used as the second-stage vehicle.

　　3. Engineering cybernetics

　　In the process of its formation, engineering cybernetics takes the engineering practice of designing stability and guidance system as the main research object. Qian Xuesen himself is the pioneer of this kind of research work.

　　4. Physical mechanics

　　In 1946, Qian Xuesen combined the physical, chemical and mechanical properties of rare gas, which was a pioneering work. In 1953, he formally put forward the concept of physical mechanics, and advocated that the macroscopic mechanical properties of matter should be determined from the microscopic laws, changing the previous method of measuring mechanical properties only by experiments, which greatly saved manpower and material resources and opened up new fields of high temperature and high pressure. In 1961, his Lectures on Physical Mechanics was officially published. Now the leader of this science is Professor Gou Qingquan. In 1984, Qian Xuesen suggested to Gou Qingquan that physical mechanics should be extended to the engineering technology of atomic and molecular design.

　　5. System engineering

　　Qian Xuesen not only refined the practice of China’s aerospace system engineering into the theory of aerospace system engineering, but also put forward the concept of the overall design department of national economic construction in the early 1980s. He also persisted in popularizing and applying the concept of aerospace system engineering to the whole country and national economic construction, and discussed the social system from the perspective of social form and open complex giant system.

　　6. System science

　　Qian Xuesen’s most important contribution to systems science is that he developed systematics and methodology of open complex giant systems.

　　7. Thinking science

　　(1) In the early 1980s, Qian Xuesen proposed to establish a department of thinking science and technology. He believed that thinking science is a science dealing with consciousness and brain, spirit and matter, subjective and objective, and it is a major department of modern science and technology. It is the need of computer technology revolution that promotes the scientific research of thinking.

　　(2) Qian Xuesen advocated that the development of thinking science should be combined with the work of artificial intelligence and intelligent computers. Based on his personal experience in the development of applied mechanics, he pointed out that the study of artificial intelligence and intelligent computers should take applied mechanics as a reference, take the road of integrating theory with practice and actually need theoretical guidance. He also believes that the establishment of thinking in images is a breakthrough in current thinking science research, and it is also the core issue of artificial intelligence and intelligent computers.

　　(3) Qian Xuesen applied the systematic scientific method to the research of thinking science, and put forward the systematic view of thinking, that is, first, based on the thinking process of logical units, he gradually built a first-order thinking system with a single thinking type, that is, he built abstract thinking, image (intuitive) thinking, social thinking and unique thinking (inspirational thinking). The second is to solve the problem of second-order thinking open large-scale system; Finally, the decision-making consultation high-order thinking open giant system.

　　8. Human science

　　Qian Xuesen put forward the theory of "human functional state" to describe the human body, an open complex giant system, and to study the structure, function and behavior of the system. Qian Xuesen is an advocate of physical science in Chinese.

　　9. Science and technology system and Marxist philosophy

　　Qian Xuesen believes that Marxist philosophy is the highest generalization of human understanding of the objective world and modern science and technology (including scientific social science). Qian Xuesen summarized the development of contemporary science and technology into ten closely related science and technology departments. The division method of these ten science and technology departments is another innovation of Qian Xuesen’s scientific classification method by applying Marxist philosophy, especially system theory. anecdote

　　1. The soul is Chinese childlike innocence.

　　"I have always believed that I will be able to return to my motherland. Today, I finally came back!" This is a very emotional remark made by Qian Xuesen, a famous scientist and rocket expert in China, to the comrades of China Travel Agency who received him when he returned to Guangzhou from the United States on October 8, 1995. He returned to China with his wife and two young children.

　　In August 1935, Qian Xuesen went to the United States to study and study aviation engineering and aerodynamics as a publicly funded international student. Before returning to China, he served as director of supersonic laboratory of California Institute of Technology and director of Guggenheim Jet Propulsion Research Center.

　　On October 1st, 1949, Mr. and Mrs. Qian Xuesen celebrated this festival with more than a dozen overseas students from China. While enjoying the moon, they poured out their feelings, rejoiced at the birth of the motherland and were full of longing for the bright future of the motherland. At this time, Qian Xuesen had a strong desire to return to the motherland at an early date and serve the country with his own expertise.

　　In July 1950, the US government decided to disqualify Qian Xuesen from participating in confidential research on the grounds that he had a friend relationship with Weinbaum, and accused Qian Xuesen of being an illegal immigrant from party member, communist party, USA. These groundless accusations were all rejected by Qian Xuesen. However, Qian Xuesen couldn’t stand all this and decided to return to his motherland immediately on the grounds of visiting relatives, ready to never return. He met with US Navy undersecretary kimble, who was in charge of his research work, and solemnly declared to kimble that he was ready to leave for home immediately. Kimble was shocked after hearing this.

　　Unconsciously, Qian Xuesen made all the preparations for returning to China, went through the formalities for returning to China, bought a plane ticket from Canada to Hong Kong, and handed over the luggage to the handling company for shipment.

　　However, just two days before their family planned to leave Los Angeles, that is, at midnight on August 23, 1950, they suddenly received a notice from the Immigration Bureau that they were not allowed to leave the United States. At the same time, the US Customs detained all Qian Xuesen’s luggage.

　　Qian Xuesen was forced to return to California Institute of Technology, and the FBI sent someone to monitor his family and all his actions. Far from it, on September 6, Qian Xuesen was suddenly illegally detained by the FBI and sent to the Immigration Detention Center for detention.

　　After Qian Xuesen was detained for no reason, the teachers and students of California Institute of Technology and Qian Xuesen’s teacher Feng? Carmen and some American friendly people protested strongly to the Immigration Bureau, found a defense lawyer for him, and raised $15,000 bail to bail Qian Xuesen out.

　　From then on, Qian Xuesen continued to be persecuted by the Immigration Bureau. His actions were restricted by the Immigration Bureau and monitored by FBI agents. He was not allowed to leave Los Angeles where he lived, and he was regularly questioned. Qian Xuesen lost his freedom for five years.

　　然而，钱学森挚爱祖国的赤子之心反而更加炽热。他日夜思念着新中国，他坚持斗争，不断地向移民局提出离开美国回国的要求。1954年用英文写出30多万字的《工程控制论》。实际上，工程控制论与生产自动化、与电子计算机的研制和运用、与国防建设都密切相关，只不过当时美国当局没有认识到这点就是了。

　　钱学森返回祖国的斗争，也得到祖国的关怀和支持。1954年4月26日，印度支那国际会议期间，中国代表团秘书长王炳南与美国代表团负责人亚?约翰逊分别代表两国政府开始关于平民回国问题的接触。在接触中，王炳南特别指出，美国正在阻挠许多旅居美国的中国人返回中国，其中包括科学家钱学森。

　　1955年6月的一天，钱学森摆脱特务监视，在寄给在比利时亲威的信中，夹带了一封书写在香烟纸上、给全国人大常委会副委员长陈叔通的信，请求祖国帮助他早日回国。陈叔通先生收到信的当天，就把它送到周恩来总理手里。1955年8月1日中美大使级会谈在瑞士日内瓦进行，王炳南大使按照周总理的授意，以钱学森要求回国的这封信为依据，与美方交涉，迫使美国政府允许钱学森离美回国。

　　1955年9月17日，钱学森与他的夫人和两个幼儿终于乘坐美国“克利夫兰总统号”邮船，离开了洛杉矶，驶向地处东方的祖国。

　　2．坚定的马克思主义者

　　1989年8月7日，中共中央总书记江泽民和国务院总理李鹏会见了钱学森，祝贺他获得1989年国际技术与技术交流大会授予的奖励和称号，认为“钱老获得这样的荣誉是当之无愧的。这不仅是钱老个人的光荣，也是中国的光荣，是中国科学技术工程人员的光荣”；钱学森的经历，“体现了一位中国知识分子所走过的曲折道路，也集中表现了中国知识分子的光辉品德”。

　　1981年秋至1982年夏，钱学森同中国社会科学院一位朋友的多次通信，是他品格的一个方面的真实生动的写照。

　　钱学森是一位自觉的马克思主义者。他在给一位朋友的信中说：“我近30年来一直在学习马克思主义哲学，并总是试图用马克思主义哲学指导我的工作。马克思主义哲学是智慧的源泉！而且一个马克思主义者是绝不会不爱人民的，绝不会不爱国的。”

　　After Qian Xuesen left the United States in 1955, he never went there again. In 1979, his alma mater, California Institute of Technology, awarded him the title of "Outstanding Alumni", in June 1986, the Southern California Chinese Scientists and Engineers Association awarded him an award, and in 1989, the International Technology and Technology Exchange Conference awarded him an award in new york, but he didn’t go. Qian Xuesen has a very friendly feeling for the American people and American scientists. For what reason does he think that he will never set foot on American soil again in this life? In 1985, an American friend told a leader in the State Council, China, about Qian Xuesen’s visit to the United States: "In the case of the US Immigration Bureau, money may have been deport at the beginning, so it must go through some kind of Amnesty procedure to enter the country. This is where you and Ambassador Han must come forward. If you really do this, you have to plead with the US government, or invisibly admit that their original measures are correct. This will not be satisfactory in Qian’s heart. " In a letter to a leading comrade in the State Council, China on March 9, 1985, Qian Xuesen gave a very frank answer: "It is not suitable for me to go to the United States. ….. The fact is that if I go to America now, I will’ prove’ many completely wrong things, which is not what I should do. For example, I am not forced to return to my motherland by the US government; As early as 1935, before I left the motherland, I promised my classmate Dai Zhongfu, an underground party member, that I would return to serve the motherland after my studies. My decision to return to China is my own business, and I have made preparations since 1949. ….. I think this is a question of right and wrong, and I can’t be silent.History cannot be distorted. Qian Xuesen’s character on this issue is exactly what General Secretary Jiang Zemin praised for his "high national self-esteem, national self-confidence and national integrity".

　　3. The bearer of the scientific torch

　　Qian Xuesen has always insisted on writing neat letters to young people asking for advice, and has always insisted on discussing problems and refining ideas with scientists in many disciplines with neat letters. Letters are a way for Qian Xuesen to publicize his belief in Marxist philosophy, guide scientific research with Marxist philosophy, and absorb scientific achievements to continuously deepen and develop Marxist philosophy. In a letter to He Zuoxiu, Qian Xuesen said: "The philosophical problem of quantum mechanics has been arguing for more than 50 years and has not been solved. Recently, Bell inequality has been verified, and the problem has become more serious. I think our physicists and philosophers in China should devote themselves to this research, solve it satisfactorily and develop Marxist philosophy in the process. "

　　From January 7th, 1986, Qian Xuesen personally led the scientific activities of "Systematic Seminar". The young and middle-aged scientists who participated in the seminar were from China Academy of Sciences, Peking University, Beijing Normal University, China Renmin University, China Academy of Social Sciences, Ministry of Aerospace Industry and other units. At the beginning of the seminar, Qian Xuesen proposed to this group of young and middle-aged scientists that we should absorb the research results of modern natural science and use it as the building material for establishing the basic science of system science and the general theory of all systems-"systematics".

　　At the Second National Congress of the National Association for Science and Technology held on March 15th, 1979, Qian Xuesen put forward the idea that "the modernization of science and technology must drive the modernization of literature and art" and put forward the concept of "scientific literature and art" to enrich and develop the connotation of popular science. Qian Xuesen is a loyal listener of popular science programs in china national radio, and a long-term reader of advanced popular science magazines Scientific American in the United States and New Scientist in the United Kingdom.

　 　 　 　 At present, designers like Stella McCatney, who are vegetarian, and brands such as MUJI Muji, which focus on pollution-free images, are vigorously practicing environmental protection in the fashion industry. For fashion consumers who don’t like them, this kind of brand with minimalist design looks a bit out of touch, which makes people feel cold and distant.

　 　 　 　 What kind of environmentally friendly fashion do you prefer to buy?

　 　 　 　 This spring, H&M released a new season’s limited series of environmental conscious actions-this is not a big news. Many people once took a bag of old clothes to H&M’s store, threw them into their white recycling bins, and then exchanged them for a "encouragement" discount coupon, or "accidentally" bought several clothes with green labels at H&M-the reason why this series attracted people’s attention was that. Zhou Xun, Wang Luodan and Eileen were all photographed wearing them to attend activities or even walk the red carpet. They looked very different from the previous "plain-faced" environmentally-friendly fashions. In addition, they were limited series, and many "stars with the same style" were sold out on the day of listing. In fact, the red carpet dress has always been synonymous with "no environmental protection". Those gorgeous and luxurious evening dresses usually exist only for a stunning appearance, and the possibility of being repeatedly worn is almost zero. Fashionable women other than stars will also find that once they wear those party dresses in their closets on major occasions, they will basically be put in the cold. It is imperative for H&M to classify this kind of "disposable" fashion as "environmental conscious action".

　 　 　 　 Prior to this, the well-known environmentally-friendly fashions were basically made of natural fiber fabrics, such as cotton, hemp and Tencel. This season, H&M added recycled sequins and beadwork for the first time, which told everyone that environmentally-friendly fashions can also grow secular and lovely. Veronique, the regional sustainable development manager of H&M, told the author that the public has a misunderstanding about environmentally friendly fabrics, thinking that only natural fabrics are environmentally friendly. In fact, things that can be recycled are also true. For example, we started to use recycled polyester fibers to make fluffy skirts last year, like this kind of clothes that need some hardness to support the shape, natural fibers are difficult to do. She also revealed that the brand’s next goal is to gradually dilute the boundary between the "environmental conscious series" and other product lines, and hope to adopt sustainable cotton for clothing in five years, that is to say, any cotton clothing (including jeans) you can buy at H&M at that time will be environmentally friendly fashion. I’m afraid that only brands like H&M can say such a big talk, and Swedish enterprises are indeed in the forefront of the world in environmental protection. Mary Turk, the clothing director of Stadsmission Stockholm, one of the largest second-hand chain retail stores in Stockholm, once expressed her wish to the media: "The so-called sustainable fashion should become a natural and ordinary part of life. When we no longer emphasize this concept, when it is truly integrated into our lives, it is truly recognized. "

　　　　　　　　Who should pay for environmental fashion?

　　　　　　　　In China, when it comes to environmental protection fashion, the most easily associated brand should be "useless". The founder Ma can promote coarse clothes made of cotton and linen and low-carbon handicrafts from the people with an image similar to that of an ascetic, and advocate "luxury poverty". What is somewhat incompatible with the "useless" simple, natural and original ecological style is its high price. Although it claims to be not a commercial brand, but a "non-profit organization dedicated to the protection of tradition and innovation of traditional folk handicrafts", it makes people wonder whether it intends to persuade everyone to make money to support a "sustainable" brand. Why should buying fashion be equated with doing charity? MUJI, who also advocates high-quality simple living, is obviously much more close to the people in terms of price. Consumers are keen to buy its products, not to show off how rich or tasteful they are (MUJI insisted on not marking the brand LOGO on the products from the beginning), but to figure out its humanized design and soft and comfortable texture, especially cotton and linen products. MUJI claims that he will go to the farm in person to communicate with the producers and use the safe and healthy cotton cultivated in the soil without pesticides and chemical fertilizers for more than three years, but it will not increase the price of the products. As one of the earliest brands that started to use organic cotton, MUJI started with baby products, and then went to underwear. Since 2010, it has been fully promoted to all product lines, and consumers may not know these things unless they ask the shop assistants or land in official website.Because MUJI did not pass on these organic cotton from India, Turkey and Tanzania as extra costs to consumers.

　　　　　　　　It is even more impossible for brands like H&M to use eco-fashion as a marketing gimmick to raise the price (their eco-conscious action series is priced the same as other series), because their consumers are particularly sensitive to the price. Then, how are these increased costs from recycling old clothes, recycling materials, treating polluted water, and researching and developing environmental protection materials digested? Julian, the sustainable supply chain manager of H&M, said that as pioneers of cheap and fast fashion brands, they always know how to control costs. Although the income and expenditure are not balanced at present, environmental protection is a must, so they can only find ways to make environmental protection less boring. The more people are willing to consume environmental fashion in the future, the more motivated they will be to increase investment and drive the whole industry to become sustainable.

　　People’s Daily, Beijing, December 5 (Reporter Wang Hao) The reporter learned from China Three Gorges Group Co., Ltd.: Recently, one of the first batch of large-scale wind power photovoltaic base projects started construction during the 14 th Five-Year Plan period, the largest photovoltaic sand control project in China — — The 2 million kilowatts photovoltaic sand control project in Kubuqi, Mengxi base, was successfully connected to the grid.

　　The project is located in the hinterland of Kubuqi Desert in Hangjinqi, Erdos City, Inner Mongolia, with an installed capacity of 2 million kilowatts, covering an area of 100,000 mu, with an average annual power generation of about 4.1 billion kWh, saving about 1.23 million tons of standard coal and reducing carbon dioxide emissions by about 3.19 million tons each year. The project adopts advanced technologies such as minimally invasive airflow tree planting method, wind direction data method, aerial seeding by unmanned aerial vehicle and so on, and repairs an area of 100,000 mu in desert control.

　　This project is the first photovoltaic sand control project in China, in which flexible scaffold materials are widely used in desert areas. The project adopts the three-dimensional ecological photovoltaic sand control mode of "double-sided power generation on the board, double-layer ecology under the board and double-layer cultivation between the boards". Double-glass module can realize double-sided power generation on the board, which can increase the power generation by 5% to 10%; Planting high-quality herbage and medicinal materials under the board; The technology of "coupling livestock, poultry and grass" is used between boards to raise chickens first and then sheep. The successful grid connection of the project will help to improve the ecological environment of the Yellow River "Zigzag Bend" and Kubuqi Desert, and provide valuable experience for the popularization and application of photovoltaic sand control technology in desert areas.

　　On October 2, 2022, General Secretary of the Supreme Leader wrote back to all geologists of the Sixth Geological Brigade of Shandong Bureau of Geology and Minerals, and raised ardent expectations for them to carry forward their fine traditions and do a good job in mineral exploration, encouraging them to strive to write a new chapter in the "heroic geological team".

　　Take up your bags and go to the world, and walk all over the mountains before you see gold. Our reporter went to Weihai, Shandong Province, and approached the Sixth Geological Brigade, recording the exploration stories of the team members who waded through mountains and rivers, slept in the wind, and overcame difficulties and the extraordinary course of prospecting for the country, and felt the fine tradition of patriotic dedication, pioneering and innovative, and hard struggle … …

　　— — Editor

　　Shixian Li, an 86-year-old former deputy chief engineer of the Sixth Geological Brigade of Shandong Bureau of Geology and Minerals, opened a drawer and took out a People’s Daily dated October 5, 2022. He read it word by word. "I read the reply from the General Secretary again and again, and I was very excited and encouraged … …” Shixian Li said.

　　Since its establishment in 1958, it has completed drilling footage of more than 5 million meters, equivalent to the height of more than 600 Mount Everest. Accumulated proven gold resources are more than 2,810 tons, making it the geological team with the most gold prospecting in China; In 1992, he was awarded the honorary title of "Heroic Geological Team with Outstanding Achievements and Selfless Dedication" by the State Council … … Close the newspaper, Shixian Li talked about the glorious course of Team Six.

　　Searching for gold to serve the country and breaking the traditional prospecting model

　　■ The first super-large altered rock type gold deposit in China has been found.

　　Shandong Jiaodong Zhaoyuan, known as "Jincheng Tianfu", has a local folk song: "The golden mule goes, the mill turns, and all it grinds is Jin Doudou." Legend has it that it’s not easy to get "Jin Doudou", you have to open the mountain gate first. In 1958, a 94-member exploration team advanced to Zhaoyuan and took the first step in searching for gold for the country. This team is the predecessor of the Sixth Team.

　　In 1960, Shixian Li graduated from the Geology Department of Shandong University, and was assigned to the Sixth Team, just in time for the "General Prospecting War". During the day, the team members searched for clues, leveled alleys and dug shallow wells, and at night, they spread hay, paved the floor and made plans. Shixian Li made up his mind: We must dig up several "Jin Doudou" for our country!

　　At the beginning of the construction of the team, the members of the sixth team just circled in the gold-bearing quartz vein type gold mine. "At that time, by foreign experts ‘ The large fault zone only guides ore but does not store it ’ Because of the influence of the conclusion, we regard the great fault zone as a restricted area for prospecting, and have never ‘ Step beyond the line ’ 。” Shixian Li said.

　　Are there any other types of large gold deposits? On the coast of Bohai Sea and Laizhou Bay, there is a small island surrounded by water on three sides — — Sanshan island. Stepping on a foot thick snow and facing the biting cold wind, the six team members went to Sanshan Island; After sampling and testing, it is found that there is a new type of gold mine here — — Altered rock type gold deposit in fracture zone.

　　This is a great discovery! "For this discovery, the members of the six teams fought bravely, and even some members gave their precious lives." Shixian Li said.

　　In 1966, Zhang Yuzhi was appointed as the technical director of Sanshan Island regional census, when he had just undergone major lung surgery. Every morning, he waded through the water island to select points and take samples, and at dusk, he returned with his ore on his back … … The leader of the unit was afraid that his body could not stand it and wanted to transfer him back to the office, but Zhang Yuzhi chose to stick to it: "The country asked us to find gold. How can we find it when people are not in the wild?" At the last moment of his life, he put on hiking shoes and walked around the ward until he never stood up again.

　　On the basis of general survey and exploration, the mining exploration report compiled by Zhang Yuzhi passed the evaluation, and the first super-large altered rock type gold deposit in China was found! "This discovery has broken the traditional prospecting model." Shixian Li said, "Soon, we found a super-large Jiaojia gold mine in the middle of another fault zone; I touched Xincheng Gold Mine, Matang Gold Mine and Dongji Gold Mine. "

　　Finding the mine is only the first step. The team members feel that it is an urgent task to analyze and summarize the theory of new types of gold deposits and guide gold exploration. In 1971, the team set up a comprehensive geological research group, which was headed by Shixian Li. One day in 1976, in a small farmhouse, Shixian Li got together with his team members to discuss … …

　　"If the gold mine is found, you must first name it." Shixian Li said. "There are Carlin-type gold mines and Rand-type gold mines abroad. Why can’t we call them Jiaojia-type?" "You must put ‘ Broken zone ’ Crown, this is the main feature … …”

　　Everyone said a word to me, and finally determined the name of the mine. In 1977, at the Second National Gold Geology Conference, "Jiaojia-style altered rock gold deposit in fracture zone" was officially named and established. In 1985, the project achievement of Team Six, Discovery of Jiaojia New Type Gold Deposit and Its Outstanding Prospecting Effect, won the first National Science and Technology Progress Award.

　　Be brave in pioneering and March towards the depths of the earth.

　　■ "Five Golden Flowers" such as Sizhuang and Jiaojia bloom for the second time.

　　In the history of gold exploration, "five golden flowers" are famous far and near. This "golden flower" is not a woman, but a genuine "golden flower".

　　In 2003, Wang Qihong, the twelfth captain of the Sixth Team, took office. Before leaving, Wang Qihong, who was usually taciturn, uttered a few words: "Thank you to the Party Committee of the Bureau for giving me this burden. If there is a ladder to the sky, I can take this team to reach for the moon!"

　　"malicious words" have been released, but the problem is in front of us! In the past, prospecting was within 500 meters below the surface, but now the surface mines and shallow mines have basically been developed. What should we do next? Looking for minerals deep in the earth, this is the only way out!

　　With the support of the Provincial Bureau of Geology and Mineral Resources, the battle headquarters with Wang Qihong as the chief commander was established, and the technical backbone was selected to form a project team. In the first month of 2005, the sky was full of snow, and the drums of the "Sizhuang Battle" were drumming, and the six teams were ready to go, heading for the underground kilometer. Some people have questioned that it is impossible to form a large mine here because of its "thin ore body, low grade, small scale and deep burial". Wang Qihong insisted: "We must break through!"

　　Jiang Hongli, the technical director of the project, locked himself in the headquarters, repeatedly looked at the drawings, turned over the exploration and mining data and analyzed the deep structural changes. After repeated deliberation, he improved the construction scheme, and made two exploratory drilling holes in the most likely ore-seeing part.

　　A hole, a dozen is 2 months, thousands of meters. The first drill hit the gold as I wished; The second drill saw a good mine, and its grade and thickness were unexpected. In the end, 52 boreholes were drilled, with a penetration of more than 40,000 meters, and the proven resources of Sizhuang Gold Mine were 51.83 tons, with a potential economic value of more than 8 billion yuan. The first "Golden Flower" was born in Sizhuang, which is the first super-large deep gold mine in China.

　　Will there be a miracle in the deep part of Jiaojia in the north of Sizhuang? Wang Qihong decided to try. With the experience of Sizhuang and the technical scheme, Jiaojia’s deep exploration was "pleasantly surprised" at the beginning, but when drilling the fourth hole, something worrying happened: no mine was hit.

　　The headquarters froze up and down … … Wang Qihong called a meeting of technicians to organize discussions, and various technical means of geological and geophysical exploration went into battle. Everyone made a bold guess: this buried "golden flower" may be dumbbell-shaped.

　　Sure enough, when the drilling went to the eighth drill, we finally found the "dumbbell handle" in the depth of 1000 meters. At the moment when the core at the expected mine site was taken up, the young team member Bao Zhongyi rushed forward and excitedly brushed away the dust on the rock: Ming Jin Shanshan shines!

　　The test results made everyone jump for joy: the highest gold grade was 110.04g/ton. During the deep exploration in Jiaojia, the Sixth Team finally discovered 105 tons of gold resources, with a potential economic value of more than 20 billion yuan. Subsequently, Zhu Guo, Li Jia, Sha Ling, Qian Chen and other "three golden flowers" bloomed for the second time … …

　　Pass from generation to generation, follow the footsteps of our predecessors

　　■ Establish four provincial and ministerial innovation platforms and six high-level scientific and technological talent innovation teams.

　　Fan Jiameng, the "three generations of the earth", followed his grandfather and uncle to the mountains when he was a child, fiddling with compasses and waving hammers. Xiao Jiameng often thought, "When can I find treasures?" After graduating from college, Fan Jiameng joined the Sixth Team. Looking forward to it is beautiful, but it is really on the road to finding gold. He played a "retreat" … …

　　In 2012, Fan Jiameng was sent to Xinjiang for exploration. Trekked more than 3,000 kilometers and arrived at Lop Nur Town Transfer Station. "On that day, the temperature was MINUS 20 degrees Celsius, and we were at ‘ Diwozi ’ I stayed up all night. " Fan Jiameng said that that night, he stayed up all night looking at the leaking roof, the uneven ground and the floor covered with debris … …

　　Arriving at the project site the next day, Fan Jiameng stood on the Gobi Desert, listening to the wind, looking at the dust all over the sky, without a trace of green, and several empty iron houses trembled in the wind! Fan Jiameng’s mood is very low: "I want to pick a load!"

　　Once, his mother called him and said sadly, "Why don’t you tell the team to go back to Shandong and go out in the wild?" Unexpectedly, grandpa’s yelling came from the other end of the phone: "Do you think geological exploration is for fun? If you can’t eat this bitterness, don’t come to the sixth team! " Mother didn’t dare to speak any more, but after a few words of comfort, she hung up the phone … …

　　"At the beginning is blunt ‘ Hero Geological Team ’ Come, then retreat is not a joke? " Fan Jiameng calmed down and remembered his grandfather’s words: "Choosing geology means choosing to be with hardship and be at home in the world;" Choosing six teams is choosing responsibility. " Fan Jiameng stayed, and 10 months later they completed the exploration project of Lop Nur.

　　In order to pave the way for young scientific and technological talents to become talents, Team Six has established four provincial and ministerial innovation platforms and six high-level scientific and technological talents innovation teams. In the exploration battle of Shuiwangzhuang mining area, the youth geological project team was established in the team, and Fan Jiameng bravely took the lead and became the person in charge. Aiming at the problem that core sampling in the fractured zone is easy to damage the drill bit, their team invented and introduced innovative technologies such as "bending-proof drilling tool", "drag reduction inner pipe" and "hydraulic cutter".

　　Even with the new technology, the construction period is still urgent. They compare the progress of the project every day, find problems and think about countermeasures. One day, there was a heavy rain, and the office was blacked out, so candles could only be used for lighting; The candlelight jumped, reflecting the faces of several young people. When the statistics of the engineering quantity of the day were completed, it was sunny and sunny, and the stars were all over the sky. Eating instant noodles and looking at the starry sky, Fan Jiameng muttered, "I miss the steaming steamed buns of my mother."

　　After exploration, Shuiwangzhuang mining area has discovered a total of 186 tons of gold resources, which is the largest gold deposit discovered in Zhaoping fault zone so far. Zhaoping fault zone has thus become the third thousand-ton ore-controlling fault zone in China.

　　Go abroad and join in the construction of the "Belt and Road"

　　■ In Team Six, everyone is good.

　　In recent years, the Sixth Team has shouldered the mission entrusted by the state and helped the countries along the Belt and Road to achieve a breakthrough in prospecting. We’re leaving again! Before leaving, Zhang Peng’s wife always felt that she didn’t bring enough things, so she bought him new shoes, socks and water cups early. "I will go to Sudan next week, and it will be half a year before we meet again." Zhang Peng said.

　　In 2012, Zhang Peng followed the team to Tajikistan. The mining area is located in Pamirs, which is nearly 4000 meters above sea level. The first difficulty is to overcome altitude sickness. Oxygen is thin, Zhang Peng is always flustered and short of breath, nosebleeds flow intermittently, and his lips are cracked … …

　　The temperature in the plateau is low. Every October, the mountains are closed by heavy snow, and the draught has become a problem. You can only smash ice cubes and use the stove to make water. Cooking on the plateau, steamed bread is not ripe, bite sticky, eat a steamed bun even for the New Year. "Knock around with a hammer and take a bunch of samples back. The shoes and trousers are worn out and can only be mended by themselves." Zhang Peng recalled.

　　Loneliness is the most unbearable. "In a deserted place, it is a surprise to hear wolves barking!" Zhang Peng said that he was afraid of his family’s worries, and told his wife that his job was like a tour of the mountains and waters, which was a "pulse" for the earth. The wife complained, "Going abroad ‘ Take a pulse ’ , why so long? " Zhang Peng said, "This is a national event, and we must do our best." Finally, through core comparison, the team explored the prospecting idea of gently inclined ore bodies and completed the task ahead of schedule.

　　In 2021, Zhang Peng became the head of Sudan Project Department. Slowly, the wife understood that the husband’s job is to travel through mountains and rivers, not to travel around. "Only when the country is rich and strong, and the six teams are stable, our small family will be happy." The wife said.

　　"On Team Six, everyone is good." Ding Zhengjiang, the captain of the Sixth Team, said, "The road ahead is long, and we should carry forward ‘ Hero Geological Team ’ Fine traditions, and strive to explore big gold mines for the country. "

　　■ Reporter’s Notes

　　Adhering to the heart of serving the country by geology

　　Mount Everest, more than 8000 meters above sea level, is an unattainable height for many people. During the interview, a set of figures was shocking: "Since its establishment in 1958, the six teams have identified more than 2,810 tons of gold resources and completed drilling footage of more than 5 million meters, which is equivalent to drilling through more than 600 Mount Everest!"

　　This set of figures is the result of the blood and sweat of the six teams. In the early days of the founding of New China, the older generation of prospectors set foot on the road of searching for gold … … For the cause of the motherland, they neglected their families, paid precious youth, and some even gave their lives.

　　After more than 60 years of hurricane and rain, some of the first generation explorers of the Sixth Team have passed away, but the spirit of faith, concentration on prospecting for mines and sincere service to the country is still passed on. They are full of blood, pack up their bags, climb mountains and follow the footsteps of their predecessors … …

　　In the interview, the words of an old comrade impressed the reporter: "Gold is not full of red, but the heart of a child is full of red." Faith can move mountains. It’s a long way to find gold. I hope the Sixth Team will carry forward the past and carry forward the cause, uphold the spirit of serving the country by geology, and strive to write a new chapter of "Hero Geological Team" in the new round of breakthrough in prospecting.

　　BEIJING, Nov. 8 (Xinhua)-According to a comprehensive report, the 19-year-old son of an oil dealer in Padra, India, didn’t like studying, so he left home for nearly a month to prove his potential. When the police finally found him, they found the young man wandering around and working, and even sleeping on the street.

　　According to the report, this young man named Taka grew up with a golden spoon and is a student of Wassad Engineering College.

　　On October 14th, he left his hometown of Padra and said that he was going to school. However, Taka did not go to school, but went to Vadodara Railway Station, where he took the train to Delhi and lost contact with his family.

　　The picture was taken from The Times of India.

　　The family found that he had left his mobile phone at home, and there was no news for a long time, so he called the police. The police searched for Taka’s whereabouts according to the surveillance video, but never found his whereabouts.

　　The case seems hopeless, and the police almost want to give up looking for Taka.

　　On November 4th, local time, Taka decided to go to an upscale hotel in Simla to look for a job.

　　The manager of this hotel found that Taka’s face was immature and his clothes were not ordinary, so he doubted Taka’s identity and immediately called the police.

　　When the police found Taka, they found him sleeping on the street, then asked him to show his identity document and confirmed that he was Taka who had been missing for nearly a month, so they quickly informed Taka’s family to reunite with him.

　　When Taka’s family heard the news, they immediately came to Simla to reunite with Taka. Taka’s uncle Ketan said that now the whole family finally breathed a sigh of relief. "We have been having a hard time."

　　It is reported that Taka chose to run away from home because he didn’t like his school and didn’t like studying. He had been to Mumbai, Delhi and Sutela and worked everywhere to make a living. It is said that during Taka’s wandering, he worked as a dishwasher in a road restaurant and a clerk in a small shop.

　　Since July 4th, a new round of persistent heavy rainfall has been affecting the middle and lower reaches of the Yangtze River from the eastern part of southwest China, which has the characteristics of stable rain belt, long duration, large accumulated rainfall and high disaster risk.

　　The water level of the river is high, can it withstand this round of rainfall? How do large-scale water conservancy projects and reservoirs in the Yangtze River basin respond to the flood challenge? Adhere to the people first, life first, and implement the spirit of the important instructions of the Supreme Leader General Secretary on flood control and disaster relief work with practical actions. The China Meteorological Bureau comprehensively judged the flood control situation and launched a three-level emergency response. The Central Meteorological Observatory issued the first orange rainstorm warning this year at 18: 00 on the 7 th. Meteorological departments in areas affected by heavy rainfall such as Hubei, Hunan, Jiangxi, Anhui, Shanghai and Zhejiang closely monitored the changes of rain, water and public opinion, strengthened the joint defense of up and down linkage, and effectively played the first line of defense for meteorological disaster prevention and mitigation.

　　Hubei: scientifically dispatching flood interception and peak clipping

　　Multiple rounds of rainstorm, multi-station water level exceeding the police, and long-term wandering of rain belt … Affected by heavy rainfall, the inflow of water in the upper reaches of the Yangtze River, Wujiang River and the Three Gorges area increased significantly, and the inflow of the Three Gorges Reservoir rose rapidly. At 10: 00 on July 2, the inflow rose to 50,000 cubic meters per second, and the No.1 flood of the Yangtze River in 2020 was formed in the upper reaches.

　　On July 3rd, the Yangtze River Basin Meteorological Center held a tripartite federation chamber of commerce with the Three Gorges Cascade Dispatching Center and the Hydrology and Water Resources Survey Bureau in the upper reaches of the Yangtze River. According to the consultation, considering flood control safety and navigation demand, the Yangtze River Water Conservancy Commission issued a dispatching order to temporarily reduce the outflow of the Three Gorges Reservoir to 30,000 cubic meters per second from 6: 00 on the 5th, and evacuate some ships stranded in the Three Gorges-Gezhouba section in time to ensure navigation safety. At 16: 00 on the 5th, the outflow of the Three Gorges Reservoir was restored to 35,000 cubic meters per second. At the same time, Xiluodu Hydropower Station, Xiangjiaba Reservoir and cascade reservoirs in the middle reaches of Jinsha River were dispatched to simultaneously increase the impoundment, moderately reduce the inflow of the Three Gorges, and jointly reduce the flood control pressure in the middle and lower reaches of the Yangtze River.

　　"Accurate rain and water regime forecasting provides a decision-making basis for the scientific operation of lakes and reservoirs in the Yangtze River basin." Tian Gang, deputy director of the hydrometeorological forecasting station of the Meteorological Center of the Yangtze River Basin, said that since the flood season, the precipitation in the Yangtze River Basin has been generally high, especially in the northern part of the middle and lower reaches. The falling area has a large swing from north to south, a wide range of heavy rainfall, high rainfall intensity and obvious local floods. By scientifically dispatching the Three Gorges Reservoir to intercept floods and cut peaks, the peak-cutting rate of the No.1 flood in 2020 is about 30%.

　　Plan ahead and take action. As early as April 7th, the Meteorological Center of the Yangtze River Basin made the conclusion of rainfall forecast in the Yangtze River Basin during the main flood season this year, further developed and applied grid forecasting products with high temporal and spatial resolution, and strengthened the consultation and judgment on the fluctuating capacity and flood control dispatching of the Three Gorges Reservoir, providing strong support for the Three Gorges Reservoir to complete the fluctuating task two days ahead of schedule and vacate the flood control storage capacity of 22.15 billion cubic meters.

　　Hunan: defending against ground disasters by smelling the flood.

　　Floods in small and medium-sized rivers have risen, landslides and roads have been interrupted … On July 5 and 6, another round of heavy rain affected the northwest of Hunan Province, and there was heavy rainfall in Xiangxi Tujia and Miao Autonomous Prefecture for 10 consecutive days since June 27. The meteorological department of Hunan Province tightened the responsibility of flood control, moved at the news of the flood season, made precise efforts, and launched a "tug-of-war" with the relevant flood control departments to fully defend against geological disasters.

　　Before the onset of this rainfall process, on July 3rd, Hunan Meteorological Bureau clearly pointed out in the Judgment of Important Weather that there will still be heavy rainfall in the northwest of Zhou Xiang in the future, with the strongest period from 5th to 8th, with local rainstorm to heavy rainstorm. On July 4th, Hunan Meteorological Bureau participated in the video conference on flood control in the whole province at 10: 00, and started the four-level emergency response of meteorological disasters (rainstorm) in the northwest of Hunan at 11: 00 that day. From 3 rd to 6 th, the Provincial Meteorological Bureau and the Provincial Department of Natural Resources jointly issued a multi-phase meteorological risk warning for geological disasters.

　　On the 5th, there was a torrential rain in the northwest of Hunan, and the Dongting Lake was over-alerted, with 16 rivers in the province exceeding the alert and five large and medium-sized reservoirs in the north of central Hunan exceeding the flood season limit. In the face of intense flood, at 9: 00 on the 5th, the Provincial Meteorological Bureau upgraded the four-level emergency response to meteorological disasters (rainstorm) in northwest Hunan to three-level. That night, heavy precipitation hit again, and the Xiangxi Meteorological Observatory was brightly lit. After several sleepless nights, the forecaster still dared not relax and issued the forecast and warning in time. After receiving the early warning signal issued by the meteorological department, the flood control departments such as emergency management and water conservancy organized a comprehensive inspection of reservoirs, rivers and hidden dangers of geological disasters for the first time.

　　At 2: 21 on the 6th, Li Chengxiang, secretary of the bucket car community in Shipai Town, Longshan County, received a heavy precipitation monitoring alarm issued by the county meteorological bureau. He became more alert. Together with Huang Guanghua, an old party member in the village, he carried out a new round of inspections on the hidden dangers of geological disasters in the community in the rain, and successfully transferred Xia Zhen, a 70-year-old man living near the hidden dangers of geological disasters, to a safe place. (Yao Liu Zhu Guoguang Deng Kai Rodin)

　　Jiangxi: Safe Transfer of Targeted Early Warning

　　At 2 o’clock on July 6, the water level of Hukou Hydrological Station in Jiangxi Province rose to the warning water level of 19.5 meters, reaching the flood numbering standard, and the No.1 flood in Poyang Lake in 2020 was formed. This also means that the Jiangxi section of the Yangtze River and Poyang Lake have entered a critical period of flood control. At the same time, Jiangxi Meteorological Bureau launched a four-level emergency response to major meteorological disasters (rainstorm).

　　As this round of heavy rainfall coincided with the college entrance examination, the Provincial Meteorological Bureau timely submitted information to the provincial party committee, the provincial government and relevant departments to remind them to continue to strengthen the prevention of geological disasters such as floods and mountain torrents in small and medium-sized rivers, and be alert to the flood development in Jiujiang section of the Yangtze River and Poyang Lake. Hydropower stations and Shantang Reservoir need to strengthen flood control safety dispatching management to cope with strong convective weather such as heavy rain, lightning and strong winds.

　　From 3rd to 4th, the Provincial Meteorological Bureau launched the whole network release mechanism of red warning twice, and released the red warning information of rainstorm to mobile phone users in Dexing City and leping city City respectively, and made a good job of mass transfer in advance.

　　From 8: 00 on the 3rd to 8: 00 on the 4th, heavy rain occurred in three towns and villages in duchang county, Jiujiang City, and the rainfall in Zhouxi Town reached 157.3mm.. At 20 o’clock, mountain torrents began to pour into the home of villager Cao Xiaoping. In less than an hour, the water in his home reached his waist. Fortunately, village cadres such as Wu Xingxing, the mayor of Zhouxi Town, helped Cao Xiaoping’s family to move to the village health center in advance after receiving the rainstorm warning issued by the county meteorological bureau.

　　In yiyang county, Shangrao City, from 20: 00 on the 2nd to 20: 00 on the 5th, the average precipitation in the county was 118mm, and the precipitation in 14 meteorological monitoring stations exceeded 100mm. "Dang … Dang …" At 1 o’clock on the 4th, a burst of rapid gong sounded in Xili Village, Wanli Township, yiyang county. This is the village cadres who are organizing mass transfer after receiving the rainstorm warning message from the meteorological department. In less than two hours, the village transferred 42 people from 18 households in areas prone to geological disasters on both sides of the river. "Thanks to the timely reminder of the weather warning, we can evacuate safely." Li Houcai, a villager, looked at the old house washed away by rain and had a lingering fear. (Deng Minjia Sheng Zhijun Li Zhibo Huang Lan Huang Ying)

　　Anhui: Emergency linkage is ready.

　　At 10: 00 on July 7, the water levels of Huikou, Datong, Wuhu and Maanshan stations in the main stream of the Yangtze River in Anhui Province all exceeded the warning water level, and the tributary lakes along the Yangtze River exceeded the warning water level in an all-round way and the guaranteed water level in some sections.

　　In the face of a new round of heavy rainfall, at 11: 00 on the 5th, the emergency response of rainstorm of Anhui Meteorological Bureau was upgraded from level 3 to level 2, which further strengthened the organization and leadership, consultation and judgment, and strengthened the monitoring, forecasting and early warning services of heavy rain, short-term heavy precipitation, thunderstorms, strong winds and other strong convective weather. The Provincial Meteorological Observatory has issued yellow rainstorm warnings for many times, and pointed out that there was continuous heavy rainfall in southern Anhui before the 10th, which has the characteristics of high overlap between the heavy rainfall area and the previous period, large accumulated rainfall, strong precipitation intensity, etc. Dabie Mountain area and southern Anhui mountainous area should focus on preventing geological disasters of mountain torrents. Hefei, Tongling, Xuancheng and other 10 cities and 27 counties have also started flood control level 3 or level 4 emergency response.

　　In the past few days, the Provincial Meteorological Bureau has strengthened emergency linkage services, jointly issued geological disaster warnings with the Provincial Department of Natural Resources, issued flash flood warnings with the Provincial Department of Water Resources, jointly issued urban waterlogging warnings with the Provincial Department of Housing and Construction, and started encrypted consultations, sending three meteorological service supervision teams in flood season to inspect and guide cities (counties) that are greatly affected by heavy rainfall, and to supervise key cities. According to the meteorological forecast and early warning, the Office of the Provincial Disaster Reduction and Relief Committee launched a four-level emergency response to disaster relief at 18: 00 on the 3rd, and sent two working groups to the disaster-stricken areas to investigate the nuclear disaster. 296 working groups from all over the country have been sent to the front line to do a good job in resettlement, emergency rescue and other work.

　　While doing a good job in meteorological services for flood control, the Provincial Meteorological Bureau organized a weather news briefing for the college entrance examination to further strengthen meteorological services for the college entrance examination through new media channels such as Weibo and WeChat.

　　It is reported that the actual rainfall is basically consistent with the forecast. Affected by this, as of 16: 00 on the 6 th, there are more than ten rivers along the Yangtze River in the province that have exceeded the warning water level, and some reservoirs have risen in water level, and flood discharge is being carried out according to regulations (Wu Ran, Wang Bing)

　　Shanghai: Seamless Docking to Protect the City’s Peace

　　Affected by the Meiyu belt, as of 11: 00 on July 6, the average water level of Taihu Lake rose to 4.06 meters, exceeding the warning level of 0.26 meters.

　　Predicting the flood situation in Taihu Lake basin, Shanghai Meteorological Bureau launched a four-level emergency response to heavy rain on the 4th. On the 5th, the Municipal Meteorological Bureau upgraded to the third-level emergency response, and the Shanghai Central Meteorological Observatory (Taihu Lake Basin Meteorological Center) upgraded to the second-level emergency response.

　　These two days, a small experiment of "self-testing against coronavirus" suddenly became popular on the Internet! Experiments show that as long as you hold your breath according to the instructions in the animation, you can judge your lung function and blood oxygen level and whether you have the ability to resist coronavirus. Many people believe it and do it. So, is this experiment really reliable? "Reaching the standard" can prove that you have the ability to resist Covid-19?

[Hold your breath continuously for 24 seconds to test lung function and blood oxygen level]

　　This small test of "self-test against coronavirus" shows that as long as you can hold your breath from A to B, it means that your lung function and blood oxygen level have the ability to resist coronavirus. The reporter calculated that this breath-holding time is about 24 seconds, and most people can do it. But in fact, the length of holding your breath is influenced by many other factors, such as age, height, weight and subjective will. Experts say that the time of holding your breath reflects the state of a person’s cardiopulmonary function. Usually, as long as you hold your breath for more than 30 seconds after taking a deep breath, the doctor thinks that your cardiopulmonary function is normal.

　　Liu Hong, deputy chief physician of the Department of Thoracic Surgery, Nanjing Second Hospital, said: "Holding your breath is not a matter of time, but a matter of integrating various factors. Conventionally speaking, holding your breath for more than 30 seconds can basically tolerate a chest operation. But actually I hold my breath for 20 seconds, can’t I have a chest operation? That’s not what I said. We should combine his lung function test, heart function test and electrocardiogram. "

[Doctor: It is unscientific to verify antiviral ability by holding your breath]

　　At present, the breath-holding test is only used as a supplementary means of lung function examination in clinic. This simple and rough method is not accurate, and the formal lung function examination is much more accurate. Therefore, it is not reliable to judge whether a person has the ability to resist coronavirus just by holding his breath for a long time.

　　Liu Hong said, "I got this disease, pneumonia and lung infection. Can I have a good prognosis or a bad prognosis?". This is caused by many factors, and can not be evaluated simply by a breath-holding test. This is a very wrong conclusion. Whether another ordinary people can be infected with the corresponding diseases in public places. For example, infectious diseases such as influenza and pneumonia have nothing to do with breath-holding test, but are related to personal immunity and the amount of bacteria and viruses in the environment you are exposed to. "

　　In addition, the breath-holding test needs to be operated under the guidance of medical staff. It is unnecessary to do the breath-holding test yourself, and it will also induce risks.

　　Liu Hong said: "For example, patients with hypertension or coronary heart disease, or patients with poor lung function and asthma, these patients may induce some diseases by holding their breath. For this group of people, this kind of self-testing may bring certain risks. "

　　Both consumers and employees in the automobile industry scoff at the mention of fake cars, but whether you admit it or not, the history of China cars is composed of one fake car after another. A few days ago, Autocar, a famous British automobile professional media, claimed that China’s automobile industry likes to copy cars with the title of Dead Ringers: History of the Chinese Copycat Car (A Goods: History of China Counterfeit Cars), and counted the most outrageous cases of China Counterfeit Cars. The original text is compiled as follows.

　　China knockoffs are rapidly becoming the main force in the local market, as shown by Zotye SR9 and Vekery V7, and they even make no secret of imitations from Porsche Macan and Volkswagen e-Up.

　　In recent years, China’s automobile industry has got rid of imitation, and many independent brands have even launched landmark competitive new cars in Europe and the United States. However, even the biggest brands have more or less had shanzhai cars in their product lineup. Therefore, please follow us to see the most outrageous knockoffs in these years.

　　Great Wall Euler R1—— Imitating Honda E and smart forfour

　　The Great Wall Euler R1 is a car made by Great Wall Motor Company, mainly for young people in cities. Its profile is exactly the same as that of smart forfour, and the front air intake grille is very similar to that of Honda E. Obviously, the name of OLA stands for "Open, Reliable and Alternative fuel", but the top speed of this mini-car is 100 km/h, which is slightly lower than that of Honda E’s 145 km/h.

　　Lifan 320-Imitate the MINI hatchback version.

　　The 320 is a 1.3-liter mini-car produced by Lifan Automobile, which was launched in the world at the 2008 Beijing Auto Show. Lifan 320 is notorious for being very similar to the MINI hatchback. In 2013, lifan 320 ushered in a redesign. After the redesign, it is no longer similar to the MINI hatchback version, but now it is more like the Fiat 500-which is amazing.

　　Landwind X7-Imitating Land Rover evoque

　　Landwind X7 was launched in 2014, and attracted much attention because it is very similar to Land Rover evoque. In fact, Land Rover was dissatisfied and took Landwind X7 to court. Although the government of China is on the side of Landwind, the price of Landwind X7 is only 14,000 pounds (about 124,000 RMB).

　　Double-ring SCEO-Imitating BMW X5

　　The front face of the double-ring SCEO may be more like the first generation Lexus RX, but there is no doubt that its outline and tail are more influenced by BMW X5. Of course, BMW will not stay out of it and take the double-ring SCEO to court. As a result, the double-ring SCEO was banned in Germany.

　　Red Scorpion in the Great Wall —— Imitating Audi R8

　　You may think that this unique shape will only appear on the Audi R8, but Great Wall Huaguan Automobile likes this design very much, so it decided to adapt it to its electric supercar Red Scorpion. The front and back design of the Great Wall Huaguan Red Scorpion is quite eye-catching, and it is not quite like Audi R8, but the outline is undoubtedly from Audi R8.

　　Changan X70A-Imitating Land Rover Discovery 4

　　For the master designer of China shanzhai cars, even the models that have not stopped production are safe. Changan X70A is a large-size SUV, produced by a car manufacturer from Chongqing, and its design is inspired by Land Rover Range Rover Discovery 4. Although the front face looks different, the profile of Changan X70A undoubtedly originated from the discovery of Land Rover.

　　Geely beauty leopard-imitating modern coolpad

　　In order to prove that the culture of China’s fake cars is nothing new, Geely Beauty Leopard successfully drew design inspiration from the front face of Hyundai Coolpad and the tail of Toyota Supra. Fortunately, Geely did not adopt the same design method for Volvo.

　　Ranger x-imitating Tesla Model S

　　Ranger is the Chinese name of Knight Rider. The internal and external design of Ranger X is very similar to that of Tesla Model S, and it is equipped with LCD lights in the style of KITT. The official said that it can accelerate 0-100 km/h in 5.6 seconds, with a cruising range of 460 km. At that time, Tesla declined to comment on this car.

　　Double-ring aristocrat-imitating smart fortwo

　　Don’t be deceived by the name Noble. This car is neither a replica of Noble M600 (the supercar launched by British sports car manufacturer Noble at the Frankfurt Motor Show in 2009), nor is its design intention noble. Although the appearance is similar to the two-seat smart fortwo, the double-ring aristocrat has four seats, but it is not clear how comfortable these four seats are.

　　Daojue Pioneer S-Aston Martin Cygnet

　　If you really want to choose an Aston? Martin’s car is a fake, and you certainly won’t choose Cygnet. But that’s what Dow Jones did. Pioneer S is an electric cottage car of Cygnet mini-car. In fact, Cygnet itself is based on Toyota iQ. Although it is not imitation, we should also indicate it. The Trailblazer S has a cruising range of 120 kilometers and a maximum speed of 60 kilometers per hour.

　　Yujie S325-Imitating Land Rover evoque

　　As a cottage car, Yujie S325 is still an innovative product. Its front face and taillights are miniature versions of Land Rover evoque, and everything else shows a tall and ugly mini-car. We don’t think Jaguar Land Rover will suffer from the impact of Yujie S325 on sales in evoque.

　　Yujie 330-Imitating Kia Picanto

　　Although the starting price of Picanto is only 7,495 pounds (about 66,000 RMB), Kia may be dissatisfied with another car of Yujie. Yujie 330 is one of the most similar cottage cars we have ever seen, but for Yujie 330, finding market living space is the real test.

　　Geely, USA and Japan 300-Imitating mercedes benz c Class

　　The tail of Geely Meiri 300 imitates another unknown China car, and the front face imitates the mercedes benz c class, even without any slight adjustment or change. It is completely the front face of the mercedes benz c class car, supplemented by the engine cover logo inspired by the Mercedes-Benz Trident Star Emblem.

　　Zotye SR9-Imitating Porsche Macan

　　The body of Porsche’s best-selling car Macan was transformed into Zotye SR9. Zotye SR9 is sold in China at a price of 12,300 pounds (about 109,000 RMB). It is equipped with a 2.0-liter turbocharged four-cylinder gasoline engine from Mitsubishi, with a maximum power of 187 HP and a peak torque of 250 Nm.

　　Vickery V7-Imitating Volkswagen e-Up

　　The newest member of the cottage family is Vicory V7, or, in layman’s terms, the Volkswagen e-Up clone. Wei Kerui V7 even imitates the brand logo of the front face, just like the BMW logo of the next cottage.

　　BYD Logo-Imitating BMW Logo

　　The BMW round logo design has also been copied, although the form has been adjusted. Although it is more decent than the cottage car, it is obvious where the font, color scheme, shape and layout of BYD logo come from. BMN, a China clothing brand, is also facing a lawsuit from BMW for its round logo. But that’s all.

　　Although the comments of British media Autocar are full of arrogance and disdain, the cottage car has always been a topic that cannot be avoided in the development of China’s automobile industry, and it is also a microcosm of the history of China’s automobile industry. Thanks to the unremitting efforts of several generations of China autobots, the pace of catching up with the century-old automobile manufacturing power has been accelerated, the gap has been continuously shortened, and more and more autonomous vehicles have gone abroad to enter the European and American markets.

　　The project involved in the 863 Program is actually a study on the safety of functional food, and the purpose of the study is not to extend the life.

　　On December 5th, Weibo, the official website of Wang Laoji, announced that according to the research results of the National 863 Program, drinking Wang Laoji can prolong life span by 10%. After this statement was released, it was quickly questioned by netizens about the authenticity of the project and the scientific nature of its conclusions. Beijing Youth Daily reporter found that herbal tea brands such as Wang Laoji were indeed used as experimental objects in a sub-project of the 863 Program. However, according to the introduction of Guangzhou CDC, which participated in the project, the center has only done relevant experiments on rats, and it is not sure that the effect of "prolonging life" is also applicable to humans. Many experts in related fields said that there is no functional food, even medicine, that can claim to prolong human life by 10%.

　　Wang Laoji claims to prolong his life by 10%

　　On December 5th, a news about herbal tea Wang Laoji was widely spread on the Internet. Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, announced at a forum that the research results of the National 863 Program show that drinking Wang Laoji can prolong life by about 10%. But soon this news caused a lot of questions.

　　The first person who questioned this idea was the CEO of Huada Gene in the same industry. On the afternoon of the 5th, Weibo, the official of Wang Laoji, announced that Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, had a high-end interaction with Yin Ye, CEO of Huada Gene, and other guests at the China Medical Industry Forum. Li Dong said that "according to the research results of the National 863 Program, drinking Wang Laoji can prolong the life span by about 10%", which was immediately highly recognized by President Yin Ye of Shenzhen Huada Gene Co., Ltd. and warmly applauded by all the guests.

　　On the afternoon of 6th, Yin Ye, CEO of BGI, forwarded the Weibo and explained that the so-called "high recognition" was just a courtesy nod. He said: "Although I am in the same industry and drink Wang Laoji, it does not mean that I recognize this conclusion. The extension of human life span is a comprehensive issue, and so far no single factor can form such a significant difference. "

　　In addition to peers, many netizens have also left messages under Wang Laoji’s official Weibo, saying, "Believe in advertising, you can prolong your life by 100%, just give your brains.". Others questioned, "How is 10% calculated? So many health products in China didn’t dare to say that, and finally lost to a drink seller. ".

　　Previously, it was caught in the "life extension storm"

　　The reporter of Beiqing Daily found that this is not the first time that Wang Laoji claimed that he has the effect of prolonging his life. On June 13th, 2013, GPHL held a special press conference, saying that "Wang Laoji Herbal Tea has the function of prolonging animal life".

　　At the press conference, GPHL said, "Through a two-year safety test on 576 mouse samples, it was initially found that the survival rate of rats in the experimental group of Wang Laoji herbal tea was better than that of the control, indicating that Wang Laoji herbal tea has the function of prolonging animal life … …”

　　At that time, it was not long before Guangzhou Pharmaceutical officially recovered the brand of Wang Laoji, and the news about "Wang Laoji prolonging life" immediately caused widespread doubts. Some netizens said, "How long does it take to extend the life of animals to be scientifically verified? It was less than two years before Guangyao officially recovered Wang Laoji, and this magical result was actually measured! " Others ridiculed, "After Radix Isatidis, another dose ‘ Shenyao ’ Available. "

　　Despite the surging doubts, the relevant person in charge of Guangzhou Pharmaceutical firmly believed in the authenticity of the efficacy of prolonging life when interviewed by the media, and said that this was only a phased achievement, and the next step would be to continue research.

　　Sure enough, on January 6, 2016, Wang Laoji once again released a "breakthrough" scientific research achievement: according to national standards and US FDA standards, the three-year safety system study of the first herbal tea product in China showed that long-term drinking of Wang Laoji herbal tea could prolong the life of animals.

　　According to reports, this conclusion is the first herbal tea project in the National 863 Plan. Guangdong Provincial Center for Disease Control and Prevention, as a scientific research unit, undertook the research on functional food safety evaluation factors.

　　"According to the requirements of national standards and American FDA standards, the research group conducted a two-year safety system study on mouse samples, and found that the survival number and expected average survival time of the experimental group of Wang Laoji herbal tea were higher than those of the control group. The statistical survival time of the experimental group of female rats given 2.90g/kg BW of Wang Laoji herbal tea was 708.2 days, while the statistical survival time of female rats in the control group was 675.1 days, which was 33.1 days higher. The difference was obvious, which proved that drinking Wang Laoji herbal tea for a long time could prolong the life of animals. At the same time, related research was carried out according to the human consumption rules of functional foods, and it was found that the physical examination indexes such as liver and kidney function, blood lipid classification and blood routine of the subjects, respiratory system, digestive system, urinary system and mood all improved to some extent, which proved that drinking Wang Laoji herbal tea for a long time had a positive effect on health. " Although specific data have been released, Wang Laoji’s function of "prolonging life" has not been widely recognized because the report only involves experiments related to rats.

　　As for the "life extension" storm, Wang Laoji responded on the evening of December 6 that the conclusion of life extension was obtained from 576 rat samples, and the relevant statements were basically consistent with the information released in 2016.

　　Survival rate is mainly used for safety verification.

　　On December 6, Huang Junming, director of the Institute of Health Toxicology of Guangdong Provincial Center for Disease Control and Prevention, admitted to the reporter of Beiqing Daily that the center had indeed participated in related 863 projects. "This project exists, and the project number is 2010aa023001. However, we only participated in the experiments of early rats and were not responsible for the human experiments. "

　　According to Huang Junming, the members of this 863 research group include several universities, several research institutions and many enterprises. At that time, it was a huge project, herbal tea was only one of the sub-items, and our team was responsible for part of the work.

　　He recalled the operation of the project to the reporter of Beiqing Daily. At that time, there were three herbal teas participating in the experiment. Among them, Jiaduobao and Wang Laoji’s experiments involved the survival rate of rats, both in red cans and green boxes. Another brand product does not involve this indicator. "Our animal experiments mainly focus on the safety of herbal tea, and the final survival rate of rats is an index to investigate the results." Huang Jun Ming said, "The experiments in which Jiaduobao and Wang Laoji participated were successful, and the animal survival rate reached the previous experimental design. The fact of the experiment was that the rats who used herbal tea lived longer than those who did not."

　　Huang Junming repeatedly stressed: "The survival rate is only the result of our experiment, not the purpose of the experiment. As to whether Wang Laoji has the function of prolonging life, I can’t give a conclusion. As for how the company publicizes, it is beyond our control. "

　　When asked about the funding of this scientific research project, Huang Junming said that all scientific research projects are supported by funds. In addition to the higher-level funding, all units that undertake the project also have inputs. "At that time, Wang Laoji, Jiaduobao and another herbal tea company provided strong support in terms of samples, materials, production, processing and experiments, which ensured the smooth progress of the project."

　　A staff member of the Guangdong Provincial Center for Disease Control and Prevention said that the research results released by Wang Laoji only mentioned about 10% of the experimental results, but did not provide specific experimental details and experimental data, and even the experimenters did not mention it. "The result is very vague and the words are unknown, so we are also verifying it further, but we are not responsible for this experimental result for the time being."

　　Expert: Herbal tea is not suitable for everyone.

　　Wang Fengzhong, deputy director of the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences, said that because rats and humans belong to different species, the conclusions obtained in rat experiments may not necessarily apply to humans.

　　Wang Fengzhong said that related efficacy tests often require a series of animal tests such as fruit flies, rats and monkeys, and finally human trials. Due to the complexity of human body structure, many ingredients that work on animals may have little effect on human body. "If we want to prolong human life by 10%, we need to prolong life by at least 30% in rat experiments."

　　Wang Fengzhong introduced that at present, there is no such thing as "prolonging life by 10%" in the related experiments of functional foods. "Now no one dares to say that it can improve human life span by 10%, and even drugs dare not claim to have such effects."

　　Wang Fengzhong said that herbal tea is not suitable for everyone to drink. "Every product has its optimal population, and it is impossible for a certain product to cure all diseases. Just as some people are allergic to eating eggs, herbal tea cannot be beneficial to everyone. "

　　Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, told the reporter of Beiqing Daily that to prove that Wang Laoji has a certificate of life extension, it is necessary to produce accurate research data. "The conclusion without data is unbelievable from my personal point of view", and there is no related research on whether it is vitamin drinks or energy drinks.

　　Fan Zhihong said that this kind of research on life extension needs to be followed for many years, and the sample is very large, and all kinds of mixed factors should be avoided, that is to say, other factors affecting life should be excluded to prove that only one factor has an impact.

　　Fan Zhihong said that she didn’t know much about the traditional Chinese medicine ingredients in the formula of Wang Laoji herbal tea, but as a high-sugar beverage, it was not suitable for everyone to drink. In addition, from the perspective of publicity, it is not appropriate to highlight the life-extending effect of products. Ordinary food cannot publicize its efficacy, even if herbal tea belongs to health care products, "prolonging life" is not among the efficacy of health care products.

　　The reporter of Beiqing Daily inquired from the website of china food and drug administration that the food and beverage branch of Guangzhou Wanglaoji Pharmaceutical Co., Ltd., the parent company of Wanglaoji Herbal Tea, registered its products as plant drinks, which means that Wanglaoji Herbal Tea is a beverage and not a health care product.

　　According to the relevant provisions of the Technical Specification for Inspection and Evaluation of Health Foods (2003 edition) issued and implemented by the Ministry of Health in 2003, health foods with health claims can declare 27 functions such as enhancing immunity, antioxidation, assisting in improving memory, relieving physical fatigue and losing weight, which does not include the function of prolonging life.

At the beginning of January, the cold wave has just dissipated, and this week, a new round of cold wave has struck strongly. The cold air has a long endurance, and the cold will run through the end of January. Autumn trousers can no longer be carried, and the ultimate equipment such as wool trousers and cotton trousers should be put on the upper body! China Weather Network released a national cotton trousers warning map, to see how many cotton trousers you should wear at least in your area.

The pictures in this article are all from "China Weather Network" WeChat WeChat official account

When it comes to the cold wave, everyone still remembers the boss-level cold wave in January 2016. This cold wave process is also coming, so which of the two processes is stronger? According to Bao Yuanyuan, a senior engineer of the National Meteorological Center, the cold wave process in early 2016 cooled down quickly and fell sharply; This process affected for a long time, and the temperature gradually decreased. Just like the fan’s direct blowing mode and head-swinging mode, one is simple and rude, and the other is long-lasting.

Compared with 2016, the overall degree of low temperature is slightly weaker, but the polar vortex continues to be stable in the northeast, and the temperature in the northeast is very low. Monitoring shows that the local temperature in Heilongjiang has fallen below -45℃ this morning. In the next three days (24-26), the freezing cold will continue, and the lowest temperature in most parts of Northeast China, northern Xinjiang and central and eastern Inner Mongolia will be below -28℃. Among them, Harbin’s performance is particularly outstanding, and it will be even colder than the "overlord cold wave" in 2016. The lowest temperature on 24th and 25th will reach -35℃, while the lowest temperature recorded in 2016 is -31.4℃. The temperature in the freezer of the refrigerator is generally -18℃, and these areas are even colder than the freezer, which is sour and unimaginable.

Therefore, people in the above areas can wear as much as they can. Autumn trousers, woolen trousers, cotton trousers, down jackets, and clothes that can be worn should be put on the body as much as possible. Temperature is more important than demeanor. If there are not enough cotton trousers at home, you can only rely on fat to make up.

This morning, the temperature in Beijing dropped to -12.3℃, a record low this winter. In the next three days, the minimum temperature will be below -10℃ from the eastern part of northwest China to Beijing, Tianjin and Hebei. On the morning of 24th-25th, the -10℃ line will reach Shandong and northern Henan. "Everyone is looking for her, and your mother calls you to wear cotton trousers." At this time, it is not your mother who thinks you are cold, but it is really cold. Put on your big cotton-padded jacket and trousers quickly.

Today, cold air has spread to Jiangsu, Anhui and Hubei, and will gradually move southward in the future. On the morning of 25th, the lowest temperature in Zhejiang, northwestern Jiangxi and southern Hunan also dropped below 0℃. In addition to being cold at night, the temperature hovers around the freezing point during the day, from morning to night. This week will be the coldest week in winter in the south, that is, it will be colder than the cold wave period in early January. What’s more, a wide range of rain, snow and freezing rain will be on the line soon, and it will last for several days. In big cities, Hefei, Nanjing, Wuhan, Changsha and Hangzhou, it has been rainy or cloudy for four or five consecutive days since Wednesday (24th). Cooling+rain and snow, this wave of wet and cold magic attacks is too fierce! Therefore, friends in the south, I suggest you put down your last stubbornness and put on cotton trousers. However, in the south where there is no heating, even if it is wrapped in a ball, it still shivers and can only be warmed by shaking.

Do you think the cold air will end on the 26th? The recent cold air can be described as endless. From 27th to 30th, due to the influence of supplementary cold air, the temperature in most parts of China will drop, and the lowest temperature in northern Guangxi, northern Guangdong and northern Fujian will also drop below freezing point. Come out to mix, sooner or later, people in South China, cold air is coming.

However, at this time, there are still some areas in China that can wear as much as possible, such as southern Hainan and Xishuangbanna, Yunnan, where the highest temperature is still around 30℃. At this time, don’t take selfies in shorts and sandals in the circle of friends, and be careful that southern friends who are frozen into dogs will hit you.

In short, in late January, most of China continued to be cold, and rain and snow covered a large area from northwest to south of the Yangtze River. Cooling down At present, friends should be more graceful and temperature-oriented. When cotton trousers should be on the upper body, how much can they wear!

It should also be noted that in addition to cooling down, everyone should pay more attention to the large-scale rain and snow this week. Among them, the snowfall concentration period is 24-25 and 27 days. It is estimated that the dividing line between rain and snow on the 24th is located in the northwest of Zhejiang, the south of Anhui, the middle of Hubei and the southwest of Shaanxi. On the 27th, the dividing line between rain and snow was further pressed southward to the areas of central Zhejiang, northwestern Jiangxi, southern Hunan and central Guizhou. According to the city forecast, Shanghai, Hangzhou, Changsha and other places may see snowfall.

In addition, this snowfall lasts for a long time, and the accumulated snowfall is large. The newly added snow depth is 8-25 cm, and the local area can reach more than 40 cm. Among them, Hubei, Anhui and Jiangsu have a high degree of overlap in two snowfall areas, so it is necessary to clear the snow in time to avoid the collapse of agricultural greenhouses and simple structures that may be caused by too much snow. Snow and ice may cause highways and airports in Shaanxi, Henan, Hubei, Anhui, Jiangsu and other places to be blocked. The public should pay attention to arranging travel plans in advance.
