　　Cctv newsAccording to the website of the Ministry of Agriculture and Rural Affairs on the 21st, in recent years, the Ministry of Agriculture and Rural Affairs has guided all localities to solidly promote the purification and regionalization management of animal diseases, speed up the construction of national animal disease purification fields, epidemic-free communities and epidemic-free areas (hereinafter referred to as "one field and two districts"), promote the improvement of biosafety management level in all links, and make positive progress. Up to now, a total of 605 "one farm and two districts" have been built in China, including 262 national animal disease purification farms, 334 epidemic-free communities and 9 epidemic-free areas.

　　From the distribution area, "one site and two districts" covers 31 provinces in China and Xinjiang Production and Construction Corps, among which the top 10 provinces are Guangxi, Shandong, Henan, Guangdong, Fujian, Shaanxi, Hunan, Jiangxi, Guizhou and Zhejiang, accounting for 55% of the national total. From the perspective of purifying diseases, "one field and two districts" involves 29 major animal diseases, such as African swine fever, highly pathogenic avian influenza, brucellosis, pseudorabies, avian leukemia and pullorum, and major zoonotic diseases and major vertical transmission animal diseases. Among them, African swine fever-free communities have the largest number, accounting for 46%. From the main types, animal disease purification farms are all large-scale livestock and poultry farms, mainly breeding livestock and poultry farms; The epidemic-free areas are mainly large-scale livestock and poultry farms, and some epidemic-free areas include auxiliary production units such as slaughtering, feed processing, harmless treatment and cleaning and disinfection; Non-epidemic areas are led by local governments and are part or all of the geographical areas of the province where they are located.

　　In the next step, the Ministry of Agriculture and Rural Affairs will continue to promote the purification and regional management of animal diseases, constantly improve the support policies and market mechanisms, accelerate the construction and evaluation of "one field and two districts", and continuously improve the biosafety protection level of the whole chain and the regional comprehensive epidemic prevention capacity through typical guidance and demonstration, so as to provide more powerful support for maintaining the production safety of animal husbandry, public health safety and national biosafety.

In recent years, China Mobile Guangdong Company has accelerated the construction of Gigabit broadband, and has built more than 54 million optical ports in the province, with more than 23 million home broadband users, including nearly 5 million Gigabit broadband users, and launched a 2000M ultra-high-speed broadband service.

It is understood that there is a saying in the communication industry that "Gigabit is easy to enter the house, but 100 Mbps is difficult to enter the house", which means that although Gigabit broadband fttp has been realized, the WiFi signal in some areas of the house is weak due to unreasonable router placement, wall blocking signals and other reasons, which affects the online experience, and some users even mistakenly think that there is a problem with broadband quality. In order to solve the "last ten meters" network perception bottleneck of gigabit home, Guangdong Mobile and Huawei jointly launched FTTR all-optical WiFi networking service, which was launched commercially in Shantou in September 2020, and promoted the upgrade of "fttp" to "fiber-to-room". Up to now, more than 150,000 mobile broadband users in the province have used this service.

According to the relevant person in charge of Guangdong Mobile, the all-optical networking adopts the "1-N mode", that is, one optical gateway plus n optical routes, and each room is equipped with an optical route, and each optical route is directly connected with the optical fiber, truly realizing the whole house WiFi without dead ends. With the help of WiFi seamless roaming technology, when users go to different rooms, the network automatically switches without feeling. The peak download rate of 2000M broadband can reach 250MB/s, and a high-definition movie can be downloaded in ten seconds. Multi-terminals can watch 4K/8K ultra-high-definition videos online, play large-scale online games and even VR/AR games at the same time, and there will be no jam.

"With the support of ultra-high-speed broadband, new applications such as cloud computers and cloud games will develop rapidly." The relevant person in charge said that the cloud computer has no hardware such as CPU, memory and hard disk. Compared with purchasing a physical computer, the cost is lower, and users can access the data stored in the cloud and use various applications by accessing the network. Cloud games put operations, rendering, storage and other links in the cloud server, and the game screen is transmitted to the local screen in real time. With the ultra-high-speed broadband guarantee, large-scale games can be played smoothly with low-configuration terminals.

In addition, the 2000M+FTTR all-optical WiFi networking supports the parallel access of more than 200 smart devices, which not only meets the Internet demand of computers, tablets and mobile phones, but also provides sufficient space for the increasing access of smart home appliances, smart security, smart pension and other devices in the digital home scene.

It is reported that Guangdong Mobile is making efforts to build a professional team of intelligent engineers to provide users with convenient and efficient networking services. For users who choose FTTR all-optical WiFi networking, engineers come to the door to tailor the solution according to the actual situation, such as laying invisible optical fibers to the room, and will make every effort to install and repair the same day.

While vigorously promoting the upgrade of home broadband, Guangdong Mobile has also launched Zhenzhi e enterprise networking service for small and medium-sized enterprises to support thousands of businesses to improve quality and efficiency. FTTR-B networking services include professional engineers’ door-to-door, networking scheme design, personalized application customization, WiFi coverage optimization, intranet rectification and optimization, integrated wiring construction, equipment installation and debugging, network inspection and operation, worry-free after-sales and other whole-process integrated services, covering an area of 3,000 square meters, providing applications such as Gigabit broadband, Gigabit WiFi and cloud computers for small and medium-sized enterprises, and deeply meeting the needs of corporate office and cloud access.

　　"The COVID-19 epidemic can be called a pandemic in terms of characteristics." On March 11th, local time, at a regular press conference held in Geneva, Switzerland, Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, announced this judgment, which attracted global attention.

　　WHO defines pandemic as "the widespread spread of a new disease around the world". At the end of January, WHO declared the COVID-19 epidemic as a "public health emergency of international concern", and now it has been declared as a global pandemic, which means that the global spread of the virus has not been curbed, and the severity and difficulty of response have increased.

　　The alarm bell has sounded, and the global anti-epidemic has reached a critical moment. In a speech, UN Secretary-General Guterres said that this announcement by WHO is a "clarion call for global action". In the face of the epidemic, it is urgent for all countries to join hands to fight.

　　What is a pandemic?

　　In 2010, the WHO website gave a simple definition of pandemic, that is, a new disease spread around the world. Among them, influenza pandemic refers to the spread of influenza virus around the world, and most people have no immunity to the virus.

　　Prevalence, infectivity and trans-regionality — — According to the standards currently adopted by WHO, a pandemic must meet these three conditions. The pandemics recognized by WHO or recognized by history mainly include the Black Death in 14th century, smallpox at the end of 19th century, and Spanish influenza in 1918. The latest pandemic recognized by WHO was the outbreak of influenza A (H1N1) from the United States and Mexico in 2009, which affected 214 countries and regions around the world for 16 months, infected at least 60 million people and caused 18,500 deaths.

　　Pandemic is not a strict definition, but a vague concept; The main consideration in defining a pandemic is not the virulence and mortality of the virus, but the scope of the virus. WHO originally divided the influenza warning level into six levels, of which five to six levels were human-to-human transmission worldwide, and the highest level was influenza pandemic, which indicated that an influenza virus broke out at the community level in at least one country outside the origin of the epidemic and posed a global spread threat.

　　In an interview with the media in late February, Jasarevic, a spokesperson for WHO, said that at present, WHO no longer uses six-level classification to evaluate infectious diseases such as influenza, but has changed to four stages: intermittent phase, alert phase, pandemic phase and transition phase.

　　In that case, why did WHO still declare COVID-19 as the first "pandemic" coronavirus infectious disease?

　　Margaret Harris, a spokeswoman for WHO, once said, "If the epidemic trend in novel coronavirus meets the standards of previous pandemics, WHO may use ‘ in communication; Pandemic ’ The word ",and the current epidemic situation has met the epidemiological conditions that constitute a global pandemic. At the same time, Tedros Adhanom Ghebreyesus also gave the judgment basis at the regular press conference on March 11th: first, based on the current spread speed, scale and severity of the virus; second, there are still countries that have not paid enough attention to and failed to prevent and control the major epidemic.

　　The global epidemic situation is worrying. In the past two weeks, the number of confirmed cases in COVID-19 outside China has increased by 13 times, and the number of affected countries and regions has increased by 2 times; At present, there are more than 125,000 confirmed cases and more than 5,000 deaths in more than 120 countries and regions. In the next few weeks, it is expected that the number of confirmed cases, deaths and the number of affected countries and regions will further increase.

　　In addition to the epidemic itself, the current lack of prevention and control in some countries has made the international community more worried. Tedros Adhanom Ghebreyesus said on March 10th that the number of confirmed cases in COVID-19 in China has obviously decreased recently, the situation of China epidemic has been reversed, and the virus is retreating. WHO has repeatedly called on the international community to make full use of the "window of opportunity" won by China to curb the spread of the virus as soon as possible, but some countries have not grasped this window well.

　　The pandemic sounded the alarm.

　　According to WHO’s daily epidemic report, as of 10: 00 central European time (17: 00 Beijing time) on March 12, the number of confirmed cases in COVID-19 outside China increased by 6,703 compared with the previous day, reaching 44,067; The number of deaths increased by 310 compared with the previous day, reaching 1440.

　　The global epidemic situation is grim, and the alarm is "loud and clear". The cumulative number of confirmed cases in European countries exceeded 30,000, and confirmed cases occurred in 27 countries of the European Union, among which the number of Italian infected people exceeded 15,000, and the cumulative number of deaths exceeded 1,000. Italian Prime Minister Conte announced on the evening of March 9, local time: starting from March 10, Italy will implement a nationwide city closure ban, and asked all commercial activities in Italy to stop except pharmacies and supermarkets that supply daily necessities. The number of infected people in France, Spain and Germany has also risen rapidly. As of March 12, the total number of confirmed cases in the three countries has exceeded 8,000.

　　"No EU country has responded to the Commission’s appeal. This does not bode well for European unity. " On March 10th, Mauricio Massari, Italian ambassador to the EU, published a signed article criticizing the EU and its member States for their slow assistance. "The Covid-19 crisis is not just a matter for a certain country, it is a ‘ European crisis ’ 。”

　　After it was revealed by the media last week that German customs intercepted a batch of masks in Switzerland, Germany once again seized a batch of gloves that should have been shipped to Switzerland this week. The situation that the EU member states are fighting each other will undoubtedly increase the difficulty of fighting the epidemic. On the evening of March 10th, local time, the heads of state of EU member states held a video conference to reflect on the current situation of ineffective response to the epidemic and discuss the next steps, and identified four urgent tasks, including limiting the spread of the virus and ensuring the supply of medical equipment, and set up an investment fund with a total amount of 25 billion euros to fight the epidemic.

　　In the United States, located on the other side of the Atlantic, the epidemic situation is also not optimistic. On March 12th, the three major stock indexes of new york stock market plunged at the opening of the day, with a drop of more than 7%. The plunge caused the US stock market to trigger the fuse mechanism again and suspend trading for 15 minutes. The soaring number of confirmed cases and the "avalanche" in the capital market are disintegrating the previous optimism in the United States.

　　On March 11, US President Trump delivered a national speech, announcing the US-Europe travel ban and canceling the campaign to be held in Colorado and Nevada. At the same time, the panic and dissatisfaction in American society are growing day by day, and the criticism of the government’s inaction in dealing with the epidemic is one after another. Robert redfield, director of the US Centers for Disease Control and Prevention, said at a congressional hearing on March 10th that some parts of the United States have missed the window of opportunity to contain the epidemic. When asked by Congressman Harley Rhoda that "some people in the United States may have died of flu on the surface, but in fact they may have died in COVID-19", redfield confirmed the above situation for the first time.

　　The epidemic situation in the Middle East continues to spread. More than 10,000 cases have been diagnosed in Iran, the "hardest hit area", and many political figures have been recruited one after another, including two vice presidents. On March 11th, the epidemic situation in Qatar, which faces Iran across the sea, took a turn for the worse, announcing a sudden increase of 238 confirmed cases in a single day, increasing the number of confirmed cases from more than 20 to 263, making it the country with the largest number of confirmed cases in the Middle East except Iran. The number of new cases in South Korea and Japan began to decline, and the prevention and control measures have achieved initial results, but they have not been completely contained. According to the report of the Central Epidemic Prevention Countermeasures Headquarters of South Korea, as of 0: 00 local time on March 13th, South Korea has added 110 confirmed cases in the past 24 hours, with a total of 7979 confirmed cases. As of 10: 30 local time on March 13th, the number of confirmed cases in COVID-19 in Japan has increased to 690, and there are 697 confirmed cases on the cruise ship "Diamond Princess" docked in Yokohama, Japan.

　　This time, COVID-19 is the first coronavirus infectious disease known as pandemic in history. In 1965, British scientist Terry discovered coronavirus in the experiment of 20,000 volunteers voluntarily catching cold, and this virus is the chief culprit of a series of infectious diseases such as influenza. At present, seven kinds of pathogenic coronaviruses have been found in human beings, including SARS in 2003, which was transmitted to humans by the atypical pneumonia virus carried by bats through the intermediate host civet cats; In 2012, the Middle East Respiratory Syndrome (MERS) coronavirus was hosted by camels, and it was brought back to South Korea by a Korean after the outbreak in the Middle East, causing large-scale spread. At the end of 2019, the coronavirus once again came to the fore.

　　However, while the world is concentrating on fighting the COVID-19 epidemic, some countries are still neglecting to respond, and even busy "throwing the pot" to blame, attacking and discrediting, failing to make effective use of precious window time, which is also one of the reasons why the global epidemic has become more severe. Faced with the virus threat full of unknowns and changes, Tedros Adhanom Ghebreyesus has repeatedly stressed that all countries "need facts, not fears", "need science, not rumors" and "need unity, not stigma".

　　How does the world respond?

　　"People have never paid so much attention to a word (pandemic). Let me give you some more important and feasible words: prevention, preparedness, public health, political leadership, and most importantly, people. " WHO said that calling this epidemic a pandemic will not change what WHO is doing or what countries should do.

　　WHO summarizes the overall strategy that countries must adopt to prevent infection, save lives and minimize the impact into four main points: preparation, response at any time, detection, protection and treatment, reduction of transmission, and innovation and learning. According to the "Prevention and Response to Pandemic Influenza" previously published by WHO, if the epidemic enters the pandemic stage, WHO and governments should take a series of countermeasures, including strengthening cooperation between national health institutions and international organizations, sharing information, providing humanitarian assistance to countries with insufficient medical resources, accelerating vaccine research and development and approval of antiviral drugs, taking measures to reduce or suspend activities that cause public gathering, and issuing travel warnings.

　　Describing COVID-19 epidemic with pandemic does not mean that the epidemic is out of control. On the contrary, thanks to strict and proven measures taken by some countries, including China, WHO says that countries can not only change the course of COVID-19 pandemic, but it will be the first controllable pandemic in history.

　　"This epidemic has made us deeply realize that the world is a whole, and countries depend on each other and only sweep ‘ Snow in front of your house ’ It won’t work. " Professor Jin Canrong, deputy dean of the School of International Studies at Renmin University of China, said in an interview that the international community must jointly prevent and control the epidemic, strengthen mutual assistance and cooperation in scientific research, epidemic monitoring, information sharing and medical assistance, and build a community of destiny to fight the epidemic.

　　In this regard, China has put it into action. At 22: 31 local time on March 12th (at 5: 31 Beijing time on the 13th), a 9-member expert group formed by the National Health and Wellness Commission and the China Red Cross flew from Shanghai to fiumicino Airport in Rome with 31 tons of medical supplies, after more than 10 hours’ flight, to support the prevention and control of the epidemic in COVID-19. This is the third team of medical experts sent by China after supporting Iran and Iraq.

　　After the outbreak, China released information openly and transparently, took the initiative to share the virus gene sequence with other countries in time, and gained valuable time for the international community to fight the epidemic through strong prevention and control measures; When the epidemic situation showed a positive trend and the prevention and control measures achieved good results, China sent anti-epidemic expert groups to Iran, Iraq and Italy, and provided anti-epidemic materials such as masks, medicines and protective clothing to Japan and South Korea. The government of China has also donated 20 million US dollars to the World Health Organization to export much-needed medical materials and equipment to some countries, and local governments and non-governmental organizations have also lent a helping hand to other countries.

　　Countries take corresponding prevention and control measures according to their national conditions, and the "China experience" can help countries to take less detours. Bruce Aylward, the foreign leader of the China-WHO joint expert inspection team in COVID-19, said that China is currently the country with the most experience and achievements in dealing with the COVID-19 epidemic in the world; China’s anti-epidemic methods can be replicated. With China’s experience, other countries don’t have to start from scratch.

　　On March 12th, the National Health and Wellness Commission and the World Health Organization jointly held an international briefing on sharing the experience of preventing and treating China in COVID-19 by multi-site video link. Ma Xiaowei, director of National Health Commission, shared China’s anti-epidemic experience from eight aspects, saying that "China’s prevention and control strategies, methods, technologies, standards and cases have stood the actual test and are willing to share them with the international community to help maintain global health and safety". On the same day, in the First Affiliated Hospital of Guangzhou Medical University, Academician Zhong Nanshan and the intensive care team of the hospital had a multi-party video connection with experts from Harvard Medical School and intensive care in the United States to discuss cooperation on clinical research in COVID-19.

　　Eighty-five years ago, Hans Zinser, an American epidemiologist, warned in his classic book Mice, Lices and History: A New History of Human Destiny that no matter how safe and orderly modern civilized life seems, bacteria, protozoa and viruses always lurk in the shadows. As long as people let their guard down, they will attack.

　　There are 800 million viruses in every square meter of space on the earth. Whether in the past, present or future, it is the common goal of all mankind to recognize and defeat viruses. At present, the "patient zero" in COVID-19 has not been found, and there are still many unknowns about the origin, spread and evolution of Covid-19, which need to be answered by researchers from all over the world.

　　"The virus has no borders, and the unity and cooperation shown by people, medical personnel and researchers in various countries in the face of the epidemic shows that the concept of a community of human destiny has been deeply rooted in the hearts of the people." Pierre piccard, a professor at the University of Paris VIII, said.

　　Under the epidemic situation, all countries share the same fate, and only by watching and helping each other can we overcome the difficulties together. As the Supreme Leader General Secretary pointed out in his reply to Bill Gates: "I have always said that human beings are a community of destiny. Unity and cooperation are the most powerful weapons to overcome epidemics that affect the safety of people in all countries. "

　　With the mass production of the 7-speed DSG gearbox equipped with LuK dry dual clutch, the DSG gearbox has entered a new stage, and the dual clutch of the dual clutch transmission DSG took five years from wet to dry.

　　The latest 7-speed DSG gearbox is instructive for the future development of automobile dual clutch system, which brings convenience, movement and comfortable driving experience. Since Volkswagen put into the market in 2003, the six-speed DSG dual-clutch automatic transmission has opened a new era of transmission, which is inseparable from the vigorous investment of Volkswagen in new technology and the vigorous expansion of parts manufacturers in the field of new technology. Standing behind Volkswagen’s first-generation DSG is Borg Warner, who is providing wet dual clutches for Volkswagen DSG, and who will stand behind the second-generation DSG?

　　In the spring of this year, Volkswagen released a 7-speed DSG gearbox. Except for adding a gear, the biggest difference with the 6-speed DSG is that it adopts a dry dual clutch. This time, which component manufacturer provided the core component-dry dual clutch for the public? That is LuK Company, headquartered in Buehl, Baden, Germany. As an expert in clutch and gearbox system in the industry, it has developed this latest dry dual clutch through close cooperation with Volkswagen. In terms of fuel economy, it is better than the gearbox equipped with wet double clutch, and compared with the traditional manual gearbox, it can save fuel consumption by about 6%.

Wet dual clutch produced by Borgwarner

　　The birth of double clutch makes the phenomenon of power interruption and passengers "nodding" when shifting gears become history. As the heart of DSG gearbox, the working principle of LuK dry dual clutch is simple: LuK’s dual clutch consists of two clutches. One of the clutches is connected with the odd gear input shaft of the gearbox: 1st gear, 3rd gear, 5th gear and 7th gear; The other clutch controls the input shaft of even gears: 2nd gear, 4th gear, 6th gear and reverse gear. For example, when the vehicle is driving in 2nd gear, 3rd gear is already in gear (only the 3rd gear clutch is not engaged). Therefore, the whole shift process can be carried out quickly, smoothly and without torque interruption. The shift is completed by electro-hydraulic control mechanism, and the driver can hardly feel the instantaneous shift and the opening and closing of a single clutch.

　　The 6-speed DSG’s multi-plate dual clutch runs in the cooling oil tank in a "wet" way, while the LuK’s dual clutch has a dry structure. The torque transmission of wet dual clutch is realized by wet clutch friction plate immersed in oil, while the torque transmission of dry clutch is realized by friction plate on clutch driven plate. Because of saving the high efficiency of torque transmission of related hydraulic system and dry clutch itself, dry system greatly improves fuel economy. The same 1.9 TDI(105 PS/ 77 kW) engine with 7-speed DSG gearbox can save more than 10% fuel compared with 6-speed wet dual clutch transmission.

　　The design of "dry" double clutch has brought many benefits, the most important of which is to significantly improve the efficiency of the gearbox system. In addition, the new generation DSG gearbox eliminates the suction filter, oil cooler and high-pressure oil pipe in the gearbox housing. Like the ordinary manual gearbox, gearbox oil is only used for lubrication and cooling of gearbox gears and bearings. Therefore, the 7-speed DSG transmission oil only needs 1.7 liters of transmission oil, while the 6-speed DSG transmission oil needs 6.5 liters. Although "dry" dual clutch has many benefits, it is limited in torque transmission. The new generation DSG gearbox is suitable for all "small" engines with maximum torque less than 250 Nm.

　　Generally speaking, the dimension of dry double clutch is slightly larger than that of wet double clutch. This is determined by the layout of the double clutch and the friction material selected. Because the external dimensions of the dry dual clutch of the 7-speed DSG gearbox are slightly larger, the rest parts should be designed to be more compact, so that it can be equipped on Polo-class small cars.

　　Since 2004, LuK has started close cooperation with Volkswagen in the development of DSG damping parts. The torsional vibration absorber in this DSG technology gearbox-dual-mass flywheel is also LuK’s product. LuK’s double clutch has been shipped to Volkswagen’s transmission factory in Kassel, Germany since the beginning of 2008. LuK’s factory in Buehl has been fully prepared for mass production (about Schaeffler Group: the German-headquartered Schaeffler Group has three famous brands: INA, LuK and FAG, and is a leading manufacturer in the global automobile industry and rolling bearing industry).
