　　[Global Network Military Report on May 7] According to a report on the website of the US Army Times on May 4, the US Navy "Seals" commandos who died in Iraq on the 3 rd were members of a rapid reaction force. Their task was to pick up a US military operational advisory group that was attacked by "Islamic State" militants in the Kurdish region of Iraq. At 7: 50 in the morning, after receiving the report of "the troops were attacked", the US military commander ordered the rapid reaction unit where the special forces staff sergeant Charlie Keating was located to join the battle and assist those US military advisers to evacuate. When Keating and his troops arrived in the village, they found that Kurdish armed forces and American military advisers were engaged in fierce melee with the enemy.

　　A national defense official said on the 3rd that at 7: 30 in the morning, about 125 "Islamic State" militants suddenly attacked the town of Taylor Askov.The militants acted in groups, with 20 armored vehicles and several car bombs, trapping more than 10 US military operational advisers. These consultants were on a one-day mission in the local area at that time, meeting with Kurdish a freedom fighter militants who had several operational outposts near the area controlled by the Islamic State.

　　"There were bullets everywhere," said Colonel steve warren, a spokesman for the US Department of Defense in Baghdad. He (Keating) was hit in this gun battle. " Warren said that Keating was shot at 9: 30 am that day, and was taken by helicopter to the US military medical center in nearby Abiel for treatment at 10: 19 am, but died shortly after.

　　Warren said that it is very rare to use the rapid reaction force in Iraq. The battle on the 3rd was the first time in several months that an American army called for emergency operations support. Keating, 31, is the third American soldier killed in Iraq since the US-led Coalition forces began to fight against the "Islamic State". At present, the US military is sending more ground troops to combat the "Islamic State" in Iraq and Syria.

　　The US military operational advisory group entered the town of Taylor Askov at dawn. The town is less than 5 miles (1 mile is about 1.6 kilometers) from the area controlled by the "Islamic State". Warren said that the U.S. military commander had ordered the rapid reaction force to assemble and stand by in advance in case the U.S. military "advice and assistance" team was in danger.

　　The "Islamic State" militants and their convoy of 20 vehicles entered the area without the knowledge of US military consultants and Kurdish armed intelligence personnel. Warren said, "You can’t monitor every inch of land all the time."

　　Warren said: "The enemy was able to gather enough troops in a very secret way, including several car bombs and some bulldozers, and of course their infantry. They were able to cross the local Kurdish armed defense line, cross the front line and advance rapidly to the town of Taylor Askov. There is their goal. "

　　The photos of the battle posted by the "Islamic State" on social media show that its militants drove several American Hummer military vehicles equipped with simple armor and a modified pickup truck equipped with heavy anti-aircraft machine guns. Warren said that there is no evidence that the "Islamic State" militants knew that there were Americans in the town when they launched the attack.

　　Warren said that shortly after the fighting started, American planes arrived over the town of Taylor Askov, including drones, F-15s and F-16s, several B-52s and A-10s. These planes dropped dozens of bombs, destroying all 20 armored vehicles of the "Islamic State" militants, as well as two cars, a bulldozer and three mortars. According to Warren’s estimation, 58 "Islamic State" militants were killed in the air raid.

　　Covid-19 is thought to originate from bats, and it is 96.2% similar to RaTG13 (collected by Shi Zhengli, Wuhan Institute of Virology, Chinese Academy of Sciences, in Yunnan, China in 2013) in nucleotide sequence level. However, it is a kind of novel coronavirus that has not been detected in humans and other animals before, and its appearance has brought many new problems to be solved urgently, including whether other pets, livestock and poultry may be infected by Covid-19 besides humans?

　　On April 8th, local time, the top academic journal Science published the paper "Susceptibility of Ferrets, Cats, Dogs, and Different Domestic Animals to SARS-coronavirus-2" online. The purpose of this study is to find out some questions: Will Covid-19 be transmitted to other animal species, thus becoming a "reservoir" of infection? Covid-19 infection has many clinical manifestations in humans, ranging from mild infection to death, so how is it manifested in other animals? With the development of vaccines and antiviral drugs, which animals can be used to simulate the effects of these drugs or vaccines on humans most accurately?

　　In order to solve these problems, research teams from the State Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and the National High-level Biosafety Laboratory of Animal Disease Prevention and Control evaluated the susceptibility of different model experimental animals, pets and livestock to Covid-19, infected Covid-19 through experiments, observed the clinical manifestations and pathological changes of vaccinated animals and cohabiting animals, and detected the viral load of organs and tissues, the emission of respiratory and intestinal viruses, and the seroconversion of antibodies against Covid-19 in animals.

　　Their research shows that Covid-19 has weak replication ability in dogs, pigs, chickens and ducks, but it can replicate efficiently in ferrets’ upper respiratory tract and cats’ respiratory system and digestive system. Experimental infected cats can spread Covid-19 through the air; Some cats can cause serious illness or even death after infection, and the illness of young cats is obviously more serious than that of older cats.

　　Histopathological observation confirmed that virus infection in cats can cause lung inflammation and intestinal mucosal damage to varying degrees. Immunohistochemical study showed that there were a large number of virus infections in mucosal epithelium and olfactory bulb cells of upper respiratory tract (nasal cavity, maxilla, tonsil), mucous gland epithelial cells of trachea and bronchial mucosa, and intestinal mucosal epithelium.

　　The correspondent of this paper is Chen Hualan, academician of China Academy of Sciences, chief scientist of the innovation team of animal influenza basic and prevention research in Harbin Veterinary Research Institute of China Academy of Agricultural Sciences, Bu Zhigao, director of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and director of the national high-level biosafety laboratory for animal disease prevention and control, and Wu Guizhen, secretary of the Party Committee of Institute of Viral Disease Prevention and Control of China CDC and director of BSL-3 laboratory. Previously, on March 31st, local time, the research team had taken the lead in publishing the research on the preprint platform bioRxiv.

　　It is worth mentioning that the National High-level Biosafety Laboratory for Animal Disease Prevention and Control is one of the existing two P4 laboratories in China, and the other is in Wuhan National Biosafety Laboratory of Chinese Academy of Sciences. All the experiments of Covid-19 infection in this study were carried out in P4 laboratory, which was approved by the Ministry of Agriculture and Rural Affairs of China. Animal research and animal welfare programs were approved by the Animal Experimental Ethics Committee of China Academy of Agricultural Sciences.

　　According to the press release issued by official website, Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences, different coronaviruses have been prevalent in mammals and poultry, but most of these coronaviruses are limited to specific species of animals and generally cannot infect humans. Similarly, several common coronaviruses in humans do not infect other animals. However, some coronaviruses from bats, such as SARS and MERS virus, can often infect many animals and humans.

　　At present, Covid-19 is popular among a wide range of people in the world, and the risk of introducing animals in close contact with human beings is increasing. Therefore, it is urgent to study the susceptibility of domestic animals in close contact with human beings to Covid-19, evaluate whether domestic animals are exposed to Covid-19 hazards and become potential intermediate hosts, and provide scientific basis for prevention and control of Covid-19.

　　In addition, in view of the current global epidemic situation of COVID-19, it is very likely that it will evolve into a common infectious disease, and it is urgent to establish a stable and reliable animal infection model to meet the needs of vaccine and drug research and development evaluation.

　　The research team stressed that the monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic. They called for close monitoring and protection of cats in epidemic areas, avoiding their contact with infectious sources and preventing them from becoming possible transmission hosts or storage hosts.

　　In addition, it was previously questioned that cats infected with COVID-19 were caused by large doses under laboratory conditions. However, in addition to this research, on April 3rd, Academician Jin Meilin, professor of the State Key Laboratory of Agricultural Microbiology of Huazhong Agricultural University, director of the Key Laboratory of Veterinary Diagnostic Preparations of the Ministry of Agriculture, director of the Research Center for Emerging Infectious Diseases of Wuhan Institute of Virology, Chinese Academy of Sciences, and researcher Shi Zhengli, director of the Key Laboratory of Highly Pathogenic Biology and Biosafety of Chinese Academy of Sciences, also published a study on the preprint platform bioRxiv. Through the investigation of cat serum, they found that the serum ELISA test of 102 cats collected after the outbreak of COVID-19 in Wuhan showed that the serum from 15 cats (14.7%) was positive for Covid-19 receptor binding domain (RBD).

　　Nadia, a 4-year-old tiger from Bronx Zoo in new york, USA, was recently diagnosed with Covid-19. On April 5, local time, the US Department of Agriculture issued a statement confirming that a tiger in a zoo in new york was diagnosed with Covid-19, and several other lions and tigers also showed symptoms of respiratory diseases. Officials at the Bronx Zoo in new york said that nadia, three other tigers and three African lions had symptoms of dry cough and loss of appetite, but they are expected to recover. Public health officials believe that these animals were infected by an asymptomatic employee.

　　Covid-19 can be replicated in the upper respiratory tract of ferrets for up to 8 days, but it will not cause serious illness or death.

　　Ferrets are often used as animal models of human respiratory viruses. Therefore, the research team first tested ferrets’ sensitivity to Covid-19.

　　Two Covid-19 strains were used in this study: F13-E from Wuhan South China Seafood Market and CTan-H from a patient infected with Covid-19.

　　The research team inoculated 10 5 PFU (Plaque Forming Unit) F13-E or CTan-H into ferrets through nose respectively, and euthanized them on the 4th day after inoculation (P.I.). The turbinate, soft palate, tonsil, trachea, lung, heart, spleen, kidney, pancreas, small intestine, brain and liver of each ferret were collected, and the viral RNA was determined by qPCR and virus titration.

　　Viral RNA：A in ferrets’ organs or tissues: A, F13-E, B, CTAN-H..

　　The results showed that viral RNA and infectious virus were detected in the turbinate, soft palate and tonsil of all four ferrets, but not in other tissues.

　　C, virus titer in organs or tissues of ferrets inoculated with F13-E, D and CTAN-H.

　　The research team believes that these results show that Covid-19 can replicate in the upper respiratory tract of ferrets, but it has not been detected in other tissues.

　　In order to study the replication dynamics of virus in ferrets, the research team intranasally inoculated 6 ferrets with 10^5pfu of F13-E(3) or CTan-H(3), and then placed them in three isolated cages. On the 2nd, 4th, 6th, 8th and 10th day, ferret nasal wash and rectal swab were collected for virus RNA detection and virus titration. At the same time, their body temperature and COVID-19 signs were monitored for two weeks.

　　Viral RNA in the nasal wash of ferrets inoculated with F13-E(E) and CTan-H(F). Viral titers in the nasal wash of ferrets inoculated with F13-E(G) and CTan-H(H).

　　The results showed that viral RNA was found in the nasal wash of all six ferrets on the 2nd, 4th, 6th and 8th day. Viral RNA was also found in some rectal swabs, but the copy number was significantly lower than that of nasal wash. Infectious virus was detected in nasal wash of all ferrets, but none of them was found in rectal swab.

　　One ferret in each group developed fever and loss of appetite on the 10th and 12th days respectively. In order to investigate whether these symptoms are caused by virus replication in the lower respiratory tract, the research team euthanized the two ferrets on the 13th day and collected their organs for virus RNA detection.

　　However, except for the ferret turbinate inoculated with CTan-H, the low copy number was detected, and no viral RNA was detected in any other tissues or organs.

　　Pathological studies showed that two ferrets euthanized on the 13th day had severe lymphoplasmacytic vasculitis and vasculitis, the number of type II alveolar cells, macrophages and neutrophils in alveolar septa and alveolar cavities increased, and the lungs had mild bronchiolitis.

　　The asterisk indicates that the animals were euthanized on the 13th day after inoculation, and the other four animals were euthanized on the 20th day.

　　Covid-19 antibody was detected in all ferrets by ELISA and neutralization test, and the antibody titers of two ferrets euthanized on the 13th day were significantly lower than those euthanized on the 20th day.

　　In order to further study whether Covid-19 was replicated in ferrets’ lungs, the research team inoculated 8 ferrets with 10^5 pfu of CTan-H through trachea, and euthanized 2 animals on the 2nd, 4th, 8th and 14th days, respectively, and detected virus RNA in tissues and organs.

　　Among the two ferrets euthanized on the second day and the two ferrets euthanized on the fourth day, the researchers only detected viral RNA； in the turbinate and soft palate of one of them. Among the two ferrets euthanized on the eighth day, viral RNA； was detected in the soft palate of one ferret and in the turbinate, soft palate, tonsil and trachea of the other ferret. No viral RNA was detected in the two ferrets euthanized on the 14th day.

　　These results indicate that Covid-19 can replicate in the upper respiratory tract of ferrets for up to 8 days without causing serious illness or death.

　　At the end of the paper, the research team also mentioned that, comparatively speaking, Covid-19 is different from other influenza viruses that can replicate in the upper respiratory tract and lower respiratory tract of ferrets, and even human SARS-CoV. Covid-19 is only replicated in ferrets’ nasal bones, soft palate and tonsils. It can also replicate in the digestive tract, but even if the virus is inoculated in the trachea, the virus is still not detected in the lungs of ferrets.

　　Cats are highly susceptible to "cat-to-cat transmission": the monitoring of cat Covid-19 should be regarded as an auxiliary means of epidemic prevention and control.

　　It is worth noting that cats and dogs are in close contact with humans, so the research team thinks that besides laboratory animals like ferrets, it is very important to know the susceptibility of domestic animals that often live with humans to COVID-19 for the control of Covid-19.

　　The research team first studied the replication of Covid-19 in cats. Five 8-month-old subadult domestic cats (inbred lines) were intranasally inoculated with 10^5pfu of CTan-H, and two of them were scheduled to be euthanized on the sixth day to evaluate the virus replication in their organs. Three cats were put in separate cages in the isolator. In order to monitor the spread of respiratory droplets, an uninfected cat was placed in a cage adjacent to each cat vaccinated with the virus.

　　Because 8-month-old cats are aggressive, it is difficult to carry out routine nasal cleaning on them. In order to avoid possible harm, the research team collected the feces of these cats and checked the viral RNA in their organs after euthanasia.

　　Virus RNA was detected in the nasal bone, soft palate and tonsils of two sub-adult domestic cats euthanized on the 6th day, and virus RNA was also detected in the trachea of one cat and the small intestine of the other cat. However, no viral RNA was detected in any lung samples of these two cats.

　　Infectious viruses were detected in the nasal bones, soft palate, tonsils and trachea of these cats, but no infectious viruses were found in the small intestine with positive viral RNA.

　　The spread of Covid-19 among cats.

　　In the study of virus transmission, RNA virus was detected in the feces of two vaccinated cats on the third day, and RNA virus was detected in the feces of all three vaccinated cats on the fifth day. Among the three cats at risk of virus exposure, viral RNA was detected in the feces of one cat on the third day.

　　Virus-infected cats with positive feces were euthanized on the 11th day. Virus RNA was detected in the soft palate and tonsils of the infected cats and in the nasal bones, soft palate, tonsils and trachea of the exposed cats, indicating that respiratory droplets spread between cats.

　　On the 12th day, the research team euthanized the remaining cats. Viral RNA was detected in the tonsils of one virus-infected cat and the nasal bone, soft palate, tonsils and trachea of another virus-infected cat, but it was not detected in any organ or tissue of the two virus-exposed cats.

　　Through ELISA and neutralization test, Covid-19 antibody was detected in all three cats inoculated with virus and one cat exposed to virus.

　　Covid-19 replicates efficiently in respiratory system and digestive system of infected cats, causing pathological damage and inflammatory reaction. Histopathological and immunohistochemical study on cats that died or were euthanized three days after virus infection. (a) The arrangement of nasal mucosa epithelium is disordered, cilia fall off (arrow), and lymphocytes in lamina propria infiltrate (arrow). (b) The tonsil epithelial cells are degenerated and necrotic, and the surface of mucosal epithelium (asterisk) is covered with cell fragments and neutrophils (arrow). (c) Epithelial degeneration and necrosis of tracheal mucosa (arrow), with mucus (asterisk) mixed with a large number of cell fragments on the surface. (d) Epithelial necrosis of tracheal mucous glands and infiltration of lymphocytes (arrow). (e) Normal lung tissue structure of uninfected cats. (f) Aggregation of inflammatory cells in pulmonary blood vessels and coagulation of fibrin (arrow). (g) A large number of macrophages and lymphocytes infiltrated in alveoli, that is, alveolar septa. (h) Infiltration and proliferation of alveoli and alveolar septitis. (i) Some cells in the epithelium of small intestine are degenerated and necrotic, and lymphocytes in the lamina propria are moderately infiltrated (arrow). (j) A large number of epithelial cells of turbinate mucosa were positive for virus antigen (brown). (k) A large number of exfoliated cells in tonsil mucosa epithelium and mucosa surface were positive for virus antigen (brown). (l) A large number of virus antigens were positive (brown) in serous cells of tracheal mucous glands. (m) A large number of small intestinal mucosal epithelial cells were positive for virus antigen (brown). Ruler line A, I = 100 μ m, B-H, J-L = 200 μ m, M = 500 μ m

　　The research team also repeated the above-mentioned replication and transmission research in sub-adult cats in young cats (70-100 days). Histopathological studies on the samples of young cats who died or were euthanized on the third day after being inoculated with the virus showed that the nasal cavity and tracheal mucosa epithelium and lungs of the two cats had a lot of damage.

　　These results indicate that Covid-19 can be effectively replicated in cats, and young cats are more susceptible to infection. More importantly, the virus can spread from cat to cat through respiratory droplets.

　　Next, the research team also studied the replication and spread of Covid-19 in dogs, and the results showed that dogs were less sensitive to Covid-19. Similar studies also show that pigs, chickens and ducks are not sensitive to Covid-19.

　　Overall, the research team found that ferrets and cats are highly sensitive to Covid-19, dogs are less sensitive, and domestic animals including pigs, chickens and ducks are not sensitive to the virus.

　　In addition, it is reported that Covid-19 uses angiotensin-converting enzyme 2 (ACE2) as its receptor to enter cells, and ACE2 is mainly expressed in type II lung cells and serous epithelial cells of ferrets’ tracheal-bronchial submucosal glands. Therefore, the research team believes that the potential mechanism to prevent Covid-19 from replicating in ferrets’ lower respiratory tract remains to be studied.

　　The results of this study show that ferrets can be used as animal models for vaccine and drug evaluation in Covid-19. Dogs, pigs, chickens and ducks are not susceptible to Covid-19, which has important guiding significance for the traceability of virus hosts; More importantly, cats are highly susceptible to Covid-19.

　　The research team called for close monitoring and protection of cats in epidemic areas to avoid contact with infectious sources and prevent them from becoming possible transmission hosts or storage hosts. The monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic.

　　[Global Times special correspondent in the United States Zhang Sisi Global Times special correspondent Wang Cong] "Whether Assange can be free is widely regarded as a judgment of the Australian government’s influence on the Biden administration in the United States." The Associated Press reported on July 30th that since the Labor government came to power last year, Australia has been trying to persuade the United States to terminate the prosecution of Assange, the founder of Wikileaks. However, in the recent annual meeting between US Secretary of State Blinken and Australian Foreign Minister Huang Yingxian, Blinken said that Assange was accused of committing a "very serious criminal act".

　　The Associated Press reported that Blinken said during the talks that Assange was "suspected to be related to one of the most serious confidential information leaks in American history", and he understood Australia’s concerns and views on this matter, but urged Australia "as a friend, we should understand the concerns of the United States". Blinken also said that Assange’s "alleged acts may cause very serious harm to US national security" or even "life-threatening". Huang Yingxian responded that Australia has "made it clear publicly for many times" and that Assange’s case has been delayed for too long. Australia hopes that the United States can withdraw these allegations and settle the case as soon as possible.

　　In addition, the Australian Sydney Morning Herald quoted Huang Yingxian as saying that the United States had "inconsistent" attitudes towards Assange and Chelsea Manning, another protagonist of the "confidential document leak case" and a former American army intelligence analyst. Manning was arrested for leaking about 700,000 confidential military and diplomatic documents to Wikileaks and was sentenced to 35 years in prison in 2013. However, in January 2017, former US President Barack Obama commuted Manning’s sentence before leaving office, which led to her release in May of that year.

　　Assange has been detained in the high-security Belmarsh prison in south London since he was arrested by the British government from the Ecuadorian embassy in London in April 2019. In June, 2022, the British Home Secretary, Pruitty Patel, approved the request of the United States to extradite Assange. In July of the same year, Assange appealed the extradition order to the British High Court. According to the relevant laws of the United States, once Assange is extradited to the United States, he will be charged with espionage and improper use of computers in the United States, and he will face a maximum of 175 years in prison.

　　According to the Sydney Morning Herald, Blinken’s statement is the "sharpest and most detailed" comment made by Biden administration officials on Assange. Blinken’s remarks mean a "rare public disagreement" between the United States and Australia, and highlight that "the Albanese government faces an arduous task in persuading Biden’s government to stop pursuing Assange". The Guardian reported that Blinken’s defense of the American accusation against Assange would be regarded as "a heavy blow to the efforts of the international community to rescue Assange".

　　Assange, 52, was born in Australia and founded the Wikileaks website in 2006. In 2010, Wikileaks exposed a large number of American diplomatic cables and confidential documents of the US military during the Afghanistan War and the Iraq War, and exposed the war crimes of the US military. In 2019, after Assange was arrested in Britain, the United States immediately requested the extradition of Assange. Australian Prime Minister Albanese has repeatedly urged the US government to terminate the lawsuit against Assange. In May this year, Albanese said that he had expressed the Australian government’s position to the American and British governments that there was no benefit in continuing to imprison Assange.

　　"Assange’s supporters reacted angrily to Blinken’s remarks." "Australia is the closest ally of the United States, and Blinken needs to understand the overwhelming view of the Australian people, that is, it is fed up with Assange’s endless imprisonment," said Barnes, legal adviser of the Australian Assange supporters organization, according to the Sydney Morning Herald. Assange must be released immediately and be reunited with his family. "

　　Xinhua News Agency, Tehran, September 21st: Talk about "America can’t be trusted" in the eyes of Iranians.

　　Xinhua News Agency reporter Gao Wencheng

　　Iranian President Leahy made it clear in an interview with the American media a few days ago: "We can’t trust the United States." This sentence is not only his personal opinion, but also the consensus of Iranian society. From a government spokesman to an ordinary librarian, Iranian society now widely believes that — — "the United States cannot be trusted."

　　The formation of this social consensus is closely related to the United States’ treachery and arrogance on the comprehensive agreement on the Iranian nuclear issue. In July 2015, after 10 years of arduous negotiations, Iran reached the the Iranian nuclear deal with the United States, Britain, France, Russia, China and Germany. However, in 2018, despite the opposition of the international community, the United States unilaterally withdrew from the Iranian nuclear deal and once again held high the sanctions stick to "exert extreme pressure" on Iran.

This is the scene of the new round of political director-level meeting of the Joint Committee of the Iranian Nuclear Comprehensive Agreement, which was filmed in Vienna, Austria on June 12, 2021. Xinhua News Agency (Photo courtesy of the EU delegation in Vienna)

　　The United States’ wanton breach of contract and indiscriminate sanctions have caused great harm to Iran’s development. After the Iranian nuclear deal was reached, the United States lifted sanctions against Iraq, and Iran’s daily average oil export once reached 2.5 million barrels, with a record economic growth rate of 13.6%. However, after the United States unilaterally broke the contract and re-imposed sanctions, Iran’s oil exports once plummeted to only 100,000 barrels per day, and the economy shrank sharply year after year.

　　Affected by US sanctions, the Iranian currency Rial has depreciated sharply in just a few years. Before the sanctions were restarted, more than 30,000 rials could be exchanged for 1 US dollar, but now it takes 30 Wan Li rials to exchange for 1 US dollar. The import and production costs of Iranian goods have increased significantly, and the shortage of materials has led to soaring prices and difficult people’s livelihood. Since 2018, the overall price in Iran has increased by about 85%, and food prices have doubled. Many Iranian families can’t make ends meet, and their lives are very tight. During the Chinese New Year, many Iranian children can’t put on new clothes, and many housewives have to think about buying a piece of meat for half a day.

　　The pain of people’s livelihood has caused Iranians to pay close attention to the Iranian nuclear talks and look forward to the early lifting of sanctions. However, the indirect negotiations between Iran and the United States on the Iranian nuclear deal’s resumption of performance have been going on for nearly a year and a half, with ups and downs in the middle, and no results have been achieved so far. The current U.S. government said one thing and did another. Although it verbally expressed its willingness to return to the Iranian nuclear deal, it inherited the previous government’s policy of "extreme pressure" on Iraq, and even during the negotiations, it continued to raise the threat tone and increase the sanctions against Iraq.

　　The current American government’s words and deeds are different, which has deepened the Iranian society’s cognition that "the United States cannot be trusted." Leahy said that if Americans want to reach an agreement, "why should they impose new sanctions on Iran during the negotiation?" Because the United States reneges on its word and has a bad track record, Iran is now very cautious in negotiations. The Iranian side has repeatedly asked the US to make a guarantee that it will not violate the contract again. Mohammad Marandi, consultant of the Iranian negotiating team, made it clear that Iran believes that corresponding provisions should be set, and if the United States breaches the contract again, it must pay the price.

　　Iranian society believes that "the United States cannot be trusted" is a silhouette of the increasing bankruptcy of American national credibility in the international arena. A number of polls show that the global influence of the United States is generally declining. In order to safeguard hegemonic self-interest, the United States has repeatedly broken the contract and "retired from the group" and provoked conflicts and confrontations. Although the United States often pretends to be so-called "democracy" and "human rights", it is hard to hide the evil consequences of its perverse actions on other countries and even the whole international community.

　　　　For today’s smart vendors, it is hard to imagine what is more important than diversified development. A few years ago, the mobile phone was still just a device for talking to us, but with the popularity of intelligent platforms, the mobile phone has changed from a communication device to a multi-functional intelligent terminal. Nowadays, in order to get rid of the homogenization of Android platform, Android manufacturers spare no effort to develop more potential of mobile phones. At this time, we will find that those manufacturers who can integrate the technologies of multiple product lines highlight more advantages than those who simply make mobile phones.

　　　　When CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and L39h (hereinafter referred to as Sony L39h) became the first product under the concept of One Sony. Just like the words in Kazuo Hirai’s mouth after the release of several DCDV devices in Berlin, "The next product can present the best part of Sony to you at one time."

G lens Sony Xperia comprehensive evaluation

　　　　In terms of configuration, Sony L39h has adopted today’s flagship configuration without any accident. After the slow pace of last year, Sony’s flagship product has finally accelerated its pace in hardware this year, and has always maintained the strongest configuration at the same level as flagship models of other international brands. Like the Sony L36h released at the beginning of this year, Sony L39h uses a 1080p display screen. However, due to the overall improvement in photographing this time, the photosensitive element has also increased to 1/2.3 inch, so the overall thickness and length and width of the fuselage have increased to some extent in Bisogni L36h. The fuselage circumference of this model is 144× 74× 8.5mm, which will be thicker in the hand than that of Bisogni L36h, but relatively, it feels more comfortable because the frame adopts a brand-new flat cutting angle.

Sony’s first image flagship 5-inch 1080p Sony L39h

　　　　Sony L39h is equipped with 2.2GHz MSM8274 Opteron 800 quad-core processor and GPU Adreno 330 image processor, and its outstanding performance is beyond doubt. At the same time, Sony L39h has also continued Sony’s waterproof and dustproof features, reaching IP55/58 level. This means that the phone has a built-in dustproof and waterproof design, that is, all ports and covers are closed, and the phone can be dustproof and can be placed in the deepest 1.5 meters of clean water for up to 30 minutes. Of course, taking photos is the biggest improvement of Sony L39h this time, and we will show it in detail later.

　　　　Regarding the screen that most users pay attention to, the performance of the IPS screen in China made us feel amazing, but this amazing performance did not continue to the Sony L39h used in our evaluation. In other words, Sony L39h, like Sony XL39h, brings users a more vivid and clear visual experience through TRILUMINOS mobile display technology and X-Reality fast image processing engine, but this is only when we watch the screen from the front. When we look at the screen of Sony L39h from the side, the visual effect is still the same as Sony L36h. This really makes us regret. I wonder if the retail version is the same as the prototype used in the evaluation.

　　　　Every year, the flagship product has maintained a high degree of consistency in appearance. In the previous interview, Mr. Morinuma, the designer of Sony L39h, explained that this is first to maintain the continuity and consistency of the design language. But also, each product will be fine-tuned in design and introduce a brand-new design based on the actual experience of users. This time, Sony L39h, like Sony L36h, has adopted a plane-like fuselage line, the camera has no protrusion, and the front and rear sides are also protected by double-sided glass, which gives people a high-end and exquisite impression visually.

Keys are still built into the screen.

　　　　The screen size of Sony L39h is consistent with that of Sony L36h, which means that the change in the length of the fuselage mainly comes from the extension of the upper and lower ends of the screen. The place above the SONY English logo near the frame that looks like a groove is both the receiver and the breathing light. When charging or resting, the lights here will light up. In addition, the front camera located next to the logo has not changed, and it is still 2 million pixels, which is enough for self-timer and can also record 1080p video. At the bottom of the screen, we obviously feel that the "chin" Bisogni L36h of Sony L39h is getting longer, but the Android buttons are still built in the screen. Many netizens wondered why Sony didn’t put the Android button on this slightly longer chin. Although we didn’t get an official explanation, after actual operation, we found that with the growth of smart size, it is actually very difficult for us to hold the Android button on the chin of a mobile phone with a size of 5 inches or more. In other words, actually putting the buttons on the screen is more user-friendly in our actual operation, and it will be better if Sony can let users choose to hide or display these three buttons by sliding up and down in the future.

MicroSIM card slot on the right side and power button and volume button.

The bottom of the right side is provided with a hanging hole and a camera shutter.

　　　　Sony L39h adopts a complete seamless design, and uses aluminum frame to make the mobile phone more durable. At the same time, it also uses this frame as an antenna through brand-new technology, which solves the disadvantage of poor call signal of metal body. Sony L39h still designed the main card slots and buttons on both sides of the fuselage, and attached dust plugs, thus maintaining a high degree of visual integration with the frame without affecting the appearance. On the right side, there is still the microSIM card slot, power button and volume button, and at the bottom, Sony L39h has added a photo shutter button, which is also convenient for users to take photos through the physical shutter button when they can’t touch the screen underwater.

The microSD card slot and data interface on the left side of the fuselage support MHL data transmission.

Metal contact for connecting magnetic attraction waterproof charging base

　　　　The design of the left card slot of Sony L39h is somewhat different from that of Sony L36h. The positions of the microSD card slot and the data interface are upside down, with the microSD card slot at the top and the data interface supporting the transmission of microUSB and MHL at the bottom. Sony L39h also has an official standard waterproof charging base, and the metal contact below the data interface is used when connecting with this base.

　　　　Another subtle change of L39h fuselage lies in the design of earphone hole, which is located at the top of the fuselage, but it is not equipped with dust plug like Sony L36h. Of course, users don’t have to worry about water coming into this earphone hole. Nowadays, the application of waterproof nano-coating technology is not uncommon. Personally, I think Sony chose to equip the interfaces on both sides of the frame with dust plugs, mainly for aesthetic considerations. In practical use, especially for people who listen to music on their mobile phones every day, the dust plug in the earphone hole is indeed redundant, and this design is just right.

The earphone hole at the top is not equipped with dust plug this time.

The bottom is almost a speaker, so it won’t block when you hold it.

　　　　Another change comes from the position of the Sony L39h speaker. Sony L36h designed the speaker at the lower right side of the fuselage, which is the position of the Sony L39h camera shutter button. In actual use, if we hold the mobile phone in one hand with the right hand, the speaker will be easily blocked, and the movement of the hand will directly cause the sound of the speaker to be loud and small. This time, the speaker is designed at the bottom, which is a good solution to this problem. This change is still very intimate.

The back is still a whole glass design.

Main camera marked with G and 1/2.3 inch sensor

XPERIA capital logo at the bottom of the back

　　　　The back of Sony L39h’s fuselage is still full of glass, and the explosion-proof membrane is also pressed for protection when it leaves the factory. This design is really beautiful, but it is also easy to be contaminated with fingerprints. Relatively speaking, white is the color with the least fingerprints among the three colors of black, white and purple. Sony’s English logo is located in the center of the fuselage. Above is the mark of NFC position, and below is the word XPERIA in all capitals. This time, it seems to emphasize the advantages of taking pictures. It is rare for Sony to mark the G word of G lens next to the camera, as well as the camera pixel size of 1/2.3 inch sensor and 20.7 million pixels. It can be seen that Sony is indeed full of confidence in taking pictures of this product.

　　　　L39h is equipped with Android 4.2 jelly bean system, but it does use a slightly different UI from Sony L36h upgraded to Android 4.2. Of course, the difference between the two is not very huge. At least as far as the main interface and the unlocking interface are concerned, we have not found any difference in the operation mode. At most, the buttons that enter the application interface are designed differently.

　
Sony L39h Home Screen and Unlocking Interface

　
The theme of Sony L39h (left) has changed a lot from Sony L36h.

　　Like the Sony L36h, the Sony L39h can change the theme and add widgets and applications to the home screen by pressing and holding the home screen. By contrast, we can see that the theme of Sony L39h has changed obviously. At the same time, when we do this operation, the presentation form of the thumbnail of the upper home screen is also different, from white translucent to black translucent, which is more visually recognizable.

　
The menu style of Sony L39h (left) application interface is also different from Sony L36h.

　
Sony L39h (left) drop-down notification bar can display more shortcut buttons.

　　　　In the application interface and drop-down notification bar, Sony L39h has also changed. In the past, we need to click the button in the interface to call out the menu of unloading and sorting, but in Sony L39h, we just slide the screen to the far left and call out the corresponding menu. When we drop down the notification bar, we can see that the shortcut operation buttons of Sony L39h have been expanded from one row to two rows, but we still don’t support setting the buttons independently.

　
Sony L39h (left) changed to X-Reality for mobile.

　　　　The change of display interface is also obvious. One of the highlights of Sony L36h is that you can manually adjust the white balance settings, but in Sony L39h, the white balance option has been cancelled. But in contrast, in Sony L39h, the original Bravia Engine 2 was replaced by the latest X-Reality for mobile, and a new backlight optimization mode was added. X-Reality for mobile can make the picture presented to us clearer and more vivid, which can be regarded as another upgrade of Bravia.

　　　　In terms of function, there is not much innovation in this L39h, which continues the characteristics of Sony L36h and the middle school, such as sketch function. On the whole, Sony L36h put all the emphasis on taking pictures. Let’s take a look at how the new camera flagship of this Android platform performs.

Sony L39h, the biggest change is taking pictures.

　　　　Sony L39h has three key words in taking pictures, namely, 1/2.3-inch large Exmor RS layered image sensor, Sony G lens, and mobile BIONZ image processor. So how does Sony explain these three keywords?

　　　　The main camera of Sony L39h has been achieved, and the 1/2.3-inch Exmor RS laminated sensor can capture more scene light and make full use of the powerful function of camera lens to shoot ultra-high resolution images. The sensor has higher sensitivity, which can reduce noise, ensure smooth and clear images, and completely reproduce all wonderful details with higher fidelity. Sony G lens is a unique feature of Sony used in cameras, which has extremely high in-focus imaging quality. In addition to sharpness, it also has excellent light gathering ability. The F2.0 large aperture 27mm wide-angle lens adopted by Sony L39h can perform better in low light and capture more light.

　　　　In addition, in order to get better detail reproduction effect, Sony L39h also uses the powerful algorithm of Sony mobile BIONZ image processor to make the shooting picture more vivid and realistic. Ultra-high pixel resolution, automatic exposure and automatic white balance ensure the accurate presentation of the colors captured by Sony G lens-while achieving brightness balance, the colors are enhanced and reproduced with rich texture layers and layers, and the effect is the same as that seen by the naked eye. The combination of 1/2.3 inch 20.7 megapixel mobile Exmor RS layered sensor and mobile BIONZ image processor can also eliminate noise.

　　　　Finally, a new breakthrough of Sony L39h lies in the zoom of 3x clear image. When shooting at a long distance, the high-resolution sensor and the mobile BIONZ image processor can provide users with an optical zoom of 81mm, bringing the picture closer, and the details are still clear. Of course, as our text shows, it is limited to zoom 0 distortion within 3 times.

Sony L39h camera basic function

Sony L39h camera interface

In advanced automatic mode, the current scene mode will be displayed in the lower right corner ("soft capture" in the picture).

Long press shutter continuous shooting needs to be set in advanced automatic mode.

　　　　In fact, the basic camera function of Sony L39h is not much different from that of the past. However, it should be noted that there were various scene modes for us to choose from in Sony in the past. However, in Sony L39h, users can’t manually select the scene mode, but can only automatically identify the most suitable scene mode at present through the "advanced automatic" mode. In addition, the function of continuous shooting requires us to open the option of long-press the shutter button continuous shooting in the setting menu of "Advanced Auto" mode. Frankly speaking, the setting of these small options is actually more complicated than before.

　　　　After reading the basic functions, let’s take a look at the featured functions in L39h. Obviously, the time shift function of Timeshift Burst, the information acquisition function of Info-eye and the shooting function of AR augmented reality are the three most interesting camera functions in Sony L39h. How to play these functions?

Info-eye function in Sony L39h

　　　　The function of Info-eye is very interesting, and we can use it as a new way to get information. Info-eye can shoot landmark buildings, characters, red wine, business cards and other formulated objects. As long as we shoot through the camera viewfinder, we can immediately see the relevant information obtained by networking.

Timeshift Burst function, the user can capture it without fail.

　　　　Timeshift Burst’s time shifting function is actually to help users capture the best photos through ultra-high-speed continuous shooting. When the shutter is pressed, the Timeshift Burst time shift function will completely record 61 images in one second before and after the shutter. After taking pictures, we just need to dial the photos in the turntable and choose the best one to save.

Seven AR Augmented Reality Scenes

　
"Diving" and "Masquerade Ball" Scenes

　　　　The fun photo function of AR augmented reality is very suitable for users with children at home, or for multi-party to enliven the atmosphere. Sony L39h provides us with seven interesting AR scenes. When the face is recognized, Sony L39h will automatically add funny accessories such as hats and glasses to the face, and the addition of these AR animations is also very intelligent. When there is a plane in the picture, these animations will be placed on the plane, and there will be no unscientific pictures such as corals floating in the air or mushrooms appearing overhead.

Sony L39h still comes with 9 kinds of filters.

　　　　In the Sony L39h, nine kinds of camera filters used in Sony are retained, so users can take photos of various small and fresh literary styles directly through the camera in their mobile phones according to their own needs.

　　　　　After introducing the innovation of L39h camera technology and the breakthrough of camera function, we should also take a look at the photo proofs of Sony L39h. Because Sony L39h is a product that has made a big breakthrough in taking pictures, we also chose the flagship Sony L36h at the beginning of this year for comparison. Although there is a big difference in the number of pixels between the two, it is really unfair to compare them, but it is also part of Sony L39h’s photo improvement. We will present the proofs in outdoor, indoor, macro and low light, and the AR proofs of Sony L39h will also be attached.

Sony L39h outdoor proofs (backlight)

Sony L36h outdoor proofs (under the sun)

　　　　The outdoor proofs in the daytime are divided into two situations, one is that there is enough light in the sun, and the other is that the shade is relatively backlit. Sony L39h’s color in the sample under the shade of the tree is more realistic than Bisogni L36h’s, and the degree of protection is higher. However, in a sunny environment, perhaps due to the large amount of light entering Sony L39h, the overall color tone is a little whiter than Sony L36h, but at the same time, the details of trees in the distance are richer.

Sony L39h/ Sony L36h indoor proofs

　　　　We took a lot of indoor proofs, and chose the shopping mall as an environment with complicated light for comparison. We can clearly see that Sony L39h’s ability to aggregate light is much better than that of Bisogni L36h. At the same time, Sony L36h appeared obvious color cast when shooting indoors, while Sony L39h restored the real color in place and controlled the noise well.

　　　　Next, we will challenge the low light and macro of L39h and the effect of AR photography. In low light, we chose indoor and outdoor situations. Strictly speaking, the two macro photos were also taken in low light environment.

Sony L36h Weak Light Proof (Indoor)

　　　　Sony L39h did a good job in the part of taking pictures in low light. First of all, while improving the brightness, the color is more natural, and there is no loss of some details. The picture of the building was taken at sunset in the evening, and both Sony L39h and Sony L36h automatically improved the overall brightness of the picture. However, we can find that the billboard in the Sony L36h sample has obvious details missing, and the building itself also appears white and the contrast is not strong enough. When shooting at night after the sky is completely dark, although the performance of Sony L36h is still satisfactory, it is obvious that there is a certain gap in saturation compared with Sony L39h, and the color of the picture is not vivid enough. In the last indoor low-light shooting session, the proofs of the two devices have obvious differences in fineness. Because Sony L36h will smear seriously in order to reduce noise when shooting in dark light, the overall picture gives us a little fuzzy feeling.

Sony L39h macro proofs

　　　　In macro aspect, both Sony L39h and the previous Sony L36h have a good performance, and the blur of the background is in place. The only difference between them is that they are both shooting outdoors in the evening, but the brightness of Sony L39h is higher.

Sony L39h AR model proofs

　
Sony L39h AR model proofs

　　　　Finally, let’s look at the photo proofs in AR augmented reality mode. Because the dinosaurs or other animations in the picture are constantly moving, the photos taken by everyone must be different. AR animation is very smart to attach to the ground or desktop, and when taking a portrait in AR mode, hats, glasses, etc. will be added to the corresponding positions and will move with the movement of the portrait. However, if we cover a part of the face with our hands, or shoot the side face, these AR elements will not appear on our face.

　　　　Generally speaking, the camera performance of Sony L39h has been greatly improved compared with Sony L36h, but in the process of actual use, we also found some shortcomings. Sony L39h’s imaging speed is a little slower, so it is easy to take a photo because of hand shaking, which will be more obvious when shooting in low light. In addition, it is AR mode, and the effect of shooting through the main camera in low light environment is not very ideal. We hope that Sony can optimize this in the future.

　　　　Next, let’s look at the multimedia performance of L39h. First of all, in terms of video, it is definitely no problem for Xiaolong 800 to play 1080p video, but some formats that Sony comes with cannot be played, and we need to play them through soft decoding of third-party players.

Sony L39h Full HD Effect

Sound effects can also be turned on in the

　　　　Sony L39h, like Sony L36h and Sony L36H we evaluated before, plays mpg with the help of a third-party player. But overall, the mobile phone plays 1080p video quite smoothly, which also provides a solid hardware foundation for Xiaolong 800. Sony L39h’s video player can also set sound effects to bring a better viewing experience.

　
Various visual effects in the audio player can be set.

　
Only when playing music can it be fixed in the unlocking interface.

　　　　In terms of audio, Sony L39h can play the audio files in m4a, ogg, wav and mp3 formats we tested, but the ape format can only be played with the help of a third-party player. The music player is not much different from the recently upgraded Sony L36h, and just like the Sony L36h, the music player can only be displayed on the unlocking interface when playing music, which means that we can’t directly access the music player from the unlocking interface at ordinary times, but need to unlock it first and then click to enter, which is somewhat inconvenient.

　
Sony L39h Fast Web Browsing Experience

Playing online web videos is quite smooth.

　　　　Perhaps because it is not the final retail version, the application of Sony L39h we evaluated is not very complete. Just for exampleWhen we want to test the online experience, we find that there is no preset in the mobile phone, so we will test it in Sony Select.Sony L39h’s performance in loading web pages, zooming and playing videos is very smooth, which makes it difficult for us to pick out any shortcomings. With enough hardware in place to support it, Sony L39h’s performance is taken for granted.

　　　　Hardware configuration is not the biggest publicity highlight of L39h this time, but in any case, for most users, hardware is always one of the first factors to consider when choosing a product. Sony L39h is equipped with a 1080p display screen, and has chosen the top Opteron 800 processor in Qualcomm at 2.2GHz, supplemented by 2GB RAM and 16GB body storage space, of which the space available for users has reached 11GB. Following the first release of this world’s earliest release, Sony L39h is also the second intelligence equipped with the Opteron 800 processor in Sony products.

Sony L39h with Opteron 800 processor

　　　　Xiaolong 800 processor is equipped with brand-new quad-core Krait 400 CPU, Adreno 330 GPU, Hexagon V5 DSP and the latest 4G LTE Cat 4 modem. Based on Snapdragon S4 Pro processor, the performance is improved by up to 75%, and the process technology is further upgraded to 28 nm HPm technology node. In the multimedia field, Opteron 800 series processors can shoot, play and display UltraHD video.

Xiaolong 800 SoC architecture (picture from Qualcomm)

　　　　In addition to the advantages of performance and speed, Xiaolong 800 processor also has excellent battery life. You can run multiple applications at the same time, surf the Internet quickly, and play videos smoothly, which are all intuitively reflected in our previous evaluation. In addition, the Snapdragon 800 series MSM8274 quad-core processor with 2.2GHz frequency adopted by Sony L39h is an asynchronous processor, and each core supplies power independently. The battery power will be accurately allocated according to the user’s use needs, thus achieving the effect of saving electricity. In addition, with the STAMINA power-saving mode in Sony L39h, the worry-free use of the whole day under normal intensity is not a problem.

The graphics performance of Adreno 330 is 50% higher than that of Adreno 320 (picture from Sony)

　　　　On the GPU side, the graphics performance of the new generation Adreno 330 is 50% higher than that of the previous generation Adreno 320, which allows users to enjoy the freshest 3D games with the best visual effects. The extremely fast performance of web browsing also comes from the performance improvement of Adreno 330.

　
Device information detected by Antutu version 4.0

　
AnTuTu’s total score is 30444.

　
Rank/comparison in AnTuTu Sony L36h

　　　　AnTuTu Runfen recently released the latest version of V4.0, in addition to the previous four test items of CPU, RAM, GPU and IO, this time it also added the user experience rating item. AnTuTu said that "in the traditional test, the performance limit of hardware will be emphasized, but the highest score of the test can not fully reflect the operating efficiency of the system", and AnTuTu thought that "multitasking ability is a very important indicator. The processing efficiency of multi-core and multi-task will directly affect the fluency of the whole system. " Therefore, AnTuTu V4.0 adds MultiTask Multithread Performance Test, and quantifies the optimization degree of UI/ROM through Dalvik. At the same time, AnTuTu V4.0 also provides 3D performance test in ES 3.0 environment, so the AnTuTu running score in this version is not comparable to that in the previous evaluation, and we can only compare it through the popular model rankings given by AnTuTu for the time being. Obviously, Sony L39h, which runs at 30444, does have the superiority of the flagship model. Compared with Sony L36h, the score is improved obviously.

Sony L39h has made a breakthrough, but there is also room for improvement.

Summary:

　　　　As a flagship product, Sony L39h is very attractive in hardware configuration and appearance. The strong performance of Xiaolong 800 and the integrated application of camera technology make this product have its own unique personality. At the same time, considering that this is the first product under the concept of One Sony, Sony L39h has also become a Sony flagship model with unique significance.

Advantages:

　　　　The application of Sony photography technology improves the imaging quality;

　　　　Aluminum seamless integrated frame ensures beautiful appearance and good call quality;

　　　　Xiaolong 800 processor, excellent performance;

　　　　IP55/58 waterproof and dustproof.

Insufficient:

　　　　If you use IPS screen, you will have a better visual effect;

　　　　If the imaging speed can be improved, the camera experience will be more perfect.

The advantages and disadvantages of the browser are considered by the display speed of various data, including graphics, etc. The test items included are very complicated. Through the test of 3d, bitops, math, string and other items, a total score is obtained, and the score is recorded in milliseconds (ms). The lower the final value, the shorter the time, which proves that the performance of the browser is better.

Sony L39h Sunspider test result is 859.1ms

　　　　Vellamo

　　　　Vellamo is a benchmark application developed by Qualcomm (similar to Neocore), which allows you to test the performance and stability of the browser, including Java script performance, rendering, networking and user interface. The result of this tool also includes several sub-items, but we only take the total score. The higher the score, the higher the optimization degree of the mobile phone to the browser and the better the web browsing experience.

　
Vellamo test results (HTML5/METAL)

　　　　Vellamo, as a mobile web ruler tool, has now been expanded to include two main modules. HTML5 module can be used to evaluate the performance of mobile web browser, while Metal module can measure the performance of CPU subsystem of mobile processor. The test suite is easy to click and use, and it is managed by modules. Vellamo can evaluate many aspects such as scrolling and zooming, 3D graphics, video performance, memory reading and writing, bandwidth peak performance and so on.

HTML5 test-

　　　　Fishbowl (set to 10 fish) FishIE Tank (set to 50 fish)

　　　　The device’s HTML5 performance is tested by a picture full of fish in the webpage, in which the number of fish can be set. During the test, the fish are swimming constantly. In the case of the same number of fish in different devices, the faster the swimming speed, the stronger the HTML5 performance, and the corresponding fps value will be given in the page. Similarly, the higher the fps value, the better.

When 10 fish, the Fishbowl test result is 60fps.

With 50 fish, the FishIE Tank test result is 51fps.

　　　　HTML5 is the next major revision of html, and it is still in the development stage. Its main benefit is to strengthen the performance of Web pages and provide better search engine optimization. The Web APP developed based on HTML5 has shorter startup time and faster networking speed, especially for mobile users, which has better picture speed and more exquisite web animation effect.

When Sony CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and Sony Xperia Z1 L39h became the first product under the concept of One Sony.

At present, Covid-19 and the flu virus are different viruses, and there is no cross protection between them, so you must get the flu when you hit COVID-19.

　　Even if you are vaccinated with influenza vaccine or Covid-19 vaccine, you should stick to personal protection, and at the same time actively exercise and enhance your immune function.

　　Jiang Rongmeng, Vice President of beijing ditan hospital, Chief Physician of Infectious Diseases:It doesn’t mean that you won’t be infected after vaccination, so we should stick to these non-pharmaceutical and non-vaccine measures in our daily life, such as wearing masks, avoiding places where people gather, doing hand hygiene well, and not washing your hands and touching your eyes and nose, which is very important for us to prevent these respiratory virus infections.
