The shape design of Greer is slightly different, mainly reflected in the shape of taillights.

  Long wheelbase brings more space performance:Greer is actually a modern brand-new Grand SantaFE. In order to distinguish it from imported brand-new Shengda, Hyundai decided to give this version a brand-new Chinese name, and the highlight of this model is that the wheelbase of the car body is lengthened (increased by 100mm) compared with the standard version, reaching 2800mm, which gives it a good space performance.

  In the actual editing experience, it is found that the performance of Greer’s sitting space has been significantly improved after the wheelbase has been lengthened. From the above figure, it is found that the same experiencer has more leg space in the second row, while Greer’s third row can also ride an adult with a height of 1.8 meters in a normal sitting position. On the whole, the performance of Greer’s sitting space in the third row is relatively narrow on the brand-new Shengda.

Three dynamic parameters of modern Greer Parameters/models R 2.2T Lambda 3.0 GDI Lambda 3.3 GDI 2.2T diesel oil 3.0L V6 gasoline 3.3L V6 gasoline maximum 197 HP (145kW)/3800rpm 264 HP (194kW)/6400rpm 286 HP (210kW)/6400rpm maximum 436N·m/1800-2500rpm 306N·m/5300rpm 337N·m/5200rpm gearbox 6-speed automatic manual integration

  Three kinds of power are available, including gasoline and diesel engines:Compared with the imported brand-new Shengda, Greer has more power options, in which the maximum output power of 2.2T is 197 HP (145kW) and the peak torque is 436N·m;; 3.0L can output 264 horsepower (194kW) and the maximum torque is 306N·m;; The power of the 3.3L engine is 286 HP (210kW) and the peak torque is 337 N m.. In the transmission part, all three engines are matched with a 6-speed automatic manual transmission. In addition, all the Gretel systems use a four-wheel drive system.

● Basic parameters:

  Hyundai Gretel has a length, width and height of 4,915/1,885/1,695 mm, and a wheelbase of 2,800 mm. The comfort version uses tires with a size of 235/60 R18, while the luxury and flagship versions use tires with a size of 235/55 R19. In addition, the interior color of Gretel is black, and users can also choose to install it in gray, beige or brown.

● New car background:

"Greer is positioned as a family-oriented user group"

  Hyundai’s brand-new Shengda long wheelbase version was first launched at the Los Angeles Auto Show at the end of November 2012. Hyundai Motor launched this version to replace its previous position. Subsequently, this new model also made its debut in China this year, and the three rows of seats in the car can still show the characteristics of relatively abundant seating space, which has attracted the attention of consumers in China. At the beginning of July, Hyundai Motor announced that the new long-wheelbase version of Shengda was called Greer in Chinese, and decided to announce its listing in China on July 18th.

● Competitors:

"Left:, right:"

  In terms of competitors, Hyundai Gretel is close to the brand-new Shengda, including Highlander and Souranto equivalent products. However, the models of Gretel and rival PK will focus on the three-row and seven-seat versions of competing products. Although the brand-new Shengda also has seven versions to choose from before, there is no obvious advantage in seating space compared with its competitors. The launch of Gretel will greatly improve this aspect. Compared with the price, Greer is still slightly higher than its competitors due to imported sales and richer configuration.

Summary:

  With the development of the automobile market, the demand for 7-seater is gradually expanding, and at the same time, consumers in China also have high requirements for riding space, so the introduction of Hyundai Greer will become an outstanding player in this market segment, and its rich configuration and power combination can also provide users with personalized needs. If you have a high car purchase budget, Greer is definitely a 7-seater SUV worth recommending. (Compile/car home Xingyu)

Former Chairman of China Association for Science and Technology: Qian Xuesen

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.

Environmental protection fashion can’t play high and cold, and everyone loves to wear it to be sustainable.

When "sustainability" and "environmental protection" become one of the hottest topics in the world today, the fashion industry can’t stay out of it. Although environmental protection is a proposition that all mankind should actively respond to, whether to buy and wear environmentally-friendly fashion is purely a personal choice. What kind of environmentally friendly fashion can please most people?

"Useless" implementation of cotton and linen coarse clothes

        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".

H&M’s limited series of environmental conscious actions in the new season
Zhou Xun is dressed in H&M2015 spring environmental conscious action limited series.

        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.

MUJI MUJI has promoted organic cotton to various product lines.

Covering an area of 100,000 mu, the largest photovoltaic sand control project in China was successfully connected to the grid.

  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.

People first, unity is strength, flood control and disaster relief visit Meteorological behavior in the middle and lower reaches of the Yangtze River in heavy rain.

  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. (Li Ao)

Video: The flood control situation in the Yangtze River Basin is grim, and meteorological departments around the country have launched emergency response and fully responded.

  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.

Is it better to eat rice or noodles Listen to an expert give you a stroke.

  Whether to eat rice or noodles is always a controversial topic. Let’s divide into several questions and take a quick look.

  Question 1

  Compared with the staple food made of white flour, which one has higher calories?

  As far as the calorie of food is concerned, it is not what food is made of, but what it is made of, how much water it contains, how much dry food it has, and whether it is added with oil and sugar. The reason why pasta is generally higher in calories is because of the above two reasons.

  A lot of pasta needs oil, even both oil and sugar. Most of those foods with stuffing have fat and thin meat stuffing and enough fat. Therefore, compared with rice, these pasta dishes have higher calories, which is understandable.

  Those pasta without oil and sugar depend on the moisture content. The moisture content of ordinary white rice is usually between 62% and 65%. Except for soft noodles, pasta will probably be lower than this value. For example, the moisture content of steamed bread is about 45%-50%, and the staple bread is even lower, only about 40%. As for dry staple foods such as naan, steamed buns and dry pancakes, the moisture content is even lower.

  Because the water content is low, eating a little more will increase the calories. Comparatively speaking, rice has more water content, less dry goods and lower calories. If you cook porridge again, it will contain more water and have lower calories in each bite.

  Therefore, compared with the same dishes, when eating rice or porridge, the quantity is better controlled, and the risk of excessive calories is slightly smaller.

  Question 2

  Compared with the staple food made of white rice and white flour, which one has higher blood sugar response?

  In terms of blood sugar reaction, white rice and white flour food are generally high, depending on the cooking method.

  Compared with white steamed bread and white bread, the glycemic index (GI) of rice is slightly lower, but not much lower. White steamed bread and white bread are 88, and white rice is 83. Whole wheat steamed bread and whole wheat bread will raise blood sugar more slowly.

  For those pasta with added fat, although the digestion speed is slow and the blood sugar rises later and lower after a meal, the food with high fat has an adverse effect on the insulin sensitivity of the next meal. Therefore, it is not a good choice for people who need to control blood sugar, and it is not a good choice for people who need to lose weight.

  Among pasta, pasta and macaroni have the lowest blood sugar reaction, and ordinary dried noodles are lower than steamed bread. Generally speaking, the higher the content of protein in flour for noodle making, the more chewy the cooked taste, and the lower the postprandial blood glucose response.

  Similarly, rice also has different processing accuracy and processing methods. If you eat germ rice, rice with some brown rice, etc., then under the premise of the same cooking method, the GI value is lower than that of polished white rice. There are also some boxed ready-to-eat rice processed in advance, and the GI value is lower than that of freshly cooked rice at that time.

  Of course, the GI value of these rice is lower than that of steamed bread and bread. Therefore, from the perspective of blood sugar stability, ordinary rice has a slight advantage.

  Question 3

  Is there any rice food with a higher blood sugar response than white rice?

  Among white rice foods, there are indeed some foods with higher blood sugar response than bread and steamed bread, that is, white rice porridge and glutinous rice food.

  White rice porridge cooked with refined white rice is very easy to digest because it is boiled to powder, so its blood sugar response is higher than that of white rice.

  However, these foods are similar to rice. Although the blood sugar peak is steep, it is not easy to cause hypoglycemia. What is more powerful is glutinous rice food. After eating them, not only did their blood sugar rise sharply, but according to the same amount of carbon and water, their postprandial blood sugar was easy to drop below the normal level.

  So, what if you add oil to glutinous rice food? Blood sugar will rise a little later, but the peak of blood sugar in the later period is big and lasts for a long time. Of course, this kind of food is added with fat and has more calories than white rice, which is not suitable for people who need to lose weight.

  Therefore, for unhealthy people who have already suffered from cardiovascular diseases or diabetes, glutinous rice foods such as fried cakes, glutinous rice balls and zongzi, as well as refined white rice foods such as rice rolls and preserved egg porridge, need to be controlled even more, because their GI values are really too high, even higher than ordinary white rice.

  Therefore, from the perspective of controlling blood sugar, glutinous rice food is the worst, worse than white bread and steamed bread.

  Question 4

  How to match rice food and pasta with whole grains?

  Rice can be incorporated into countless kinds of whole grains and legumes to make miscellaneous grains rice. Half white rice and half other miscellaneous grains (most of which need to be soaked in advance) actually taste very fragrant. It is also very simple and convenient to add some diced sweet potatoes, Chinese yam slices and taro seeds when steaming rice.

  Flour can also be added with about 20% of miscellaneous grains powder to make steamed bread, cakes, pancakes, bread and so on. However, when the addition amount exceeds 20%, the taste of pasta will become worse because gluten is seriously diluted. A small amount of mixed bean powder can be added to the noodles, which makes the taste smoother. You can also add oat flour, buckwheat flour, corn flour, etc., but the toughness of the noodles is reduced, and the cooking method is different. Home-made technology is difficult, and the overall popularity is not high.

  Therefore, from the convenience of adding whole-grain miscellaneous beans and potatoes, rice has a slight advantage.

  Question 5

  Are there enough dishes to accompany the staple food?

  Although the postprandial blood sugar response of white rice is higher than that of noodles, jiaozi and Melaleuca Cake, many people find that eating rice has better blood sugar control effect than eating these pasta, and it is also less likely to gain weight. Why is this?

  To a large extent, this is because of different eating methods and different contents.

  In addition to the low nutritional value of white rice, there are advantages in food collocation when eating rice. We seldom just eat a bowl of rice, but we have meat, fish, eggs, bean products, and vegetables, and usually there are more dishes than rice. This makes it easier to obtain relatively balanced nutrition.

  When eating noodles, there is a big bowl of noodles, and there are only a few dishes and marinades. Therefore, from the perspective of fully cooperating with various dishes, rice is still slightly dominant.

  Question 6

  Which vitamin is more, rice or pasta? Which is safer?

  Comparing rice with white flour one-to-one, protein and B vitamins in white flour are slightly higher. However, the disadvantages of rice are not so obvious after matching dishes. Rice with a large number of dishes, compared with noodles and cakes with few dishes, nutrition will win.

  From the safety point of view, rice food rarely has allergic problems, while some people eat flour with the risk of "chronic gluten allergy". For these allergic people, wheat gluten will damage the intestinal mucosal barrier, which may lead to chronic allergies to other foods. Severe wheat gluten allergy may even lead to "celiac disease". Such patients can lead a normal life only if they are completely away from all foods containing flour.

  Generally speaking, rice food and pasta have their own advantages and disadvantages. Whether it is white rice or white flour food, eating more is not conducive to preventing diabetes and cardiovascular and cerebrovascular diseases, nor to losing weight. Appropriate inclusion of whole grains is a better choice. For people who need to lose weight and prevent chronic diseases, reducing the oil and salt in the staple food, including some whole-grain miscellaneous beans and more vegetarian dishes are the key points to eat the staple food healthily.
