At present, the world economic situation is grim, complicated and changeable. The rise of trade protectionism and the COVID-19 epidemic have brought great impact on the economic and trade of all countries in the world. According to the World Bank’s forecast, the global economy will decline by 5.2% in 2020, which will be the worst year after World War II. According to the forecast of WTO, global merchandise trade will decline by 12.9% at best and 31.9% at worst in 2020.

　　Gradually form a new development pattern with domestic macro-cycle as the main body and domestic and international dual-cycle promoting each other, which is a powerful strategy to promote China’s economy to a key stage of high-quality development under the background of significant changes in the domestic and international environment. This strategy is not simply an expedient measure for the interruption of the current industrial chain supply chain due to the epidemic, but a major strategic deployment for the development of China’s open economy to a higher level. In the face of the impact of the epidemic on the economic environment, only by developing domestic circulation and integrating into international circulation can the internal potential be better brought into play.

　　As the world’s largest exporter, China’s foreign trade has been severely impacted. Since the beginning of this year, the orders of foreign trade export enterprises have dropped sharply, and the resumption of work and production is facing severe challenges. The CPC Central Committee and the State Council made an important decision to "stabilize foreign trade" in time, and launched a series of policy measures to "stabilize foreign trade", among which the General Office of the State Council recently issued the "Implementation Opinions on Supporting Export Products to Domestic Sales". All these policies are aimed at supporting marketable export commodities to explore the domestic market, so that those foreign trade enterprises that actively transform and upgrade can achieve "two incense sticks inside the wall and two incense sticks outside the wall".

　　"Export to domestic sales" is not an initiative to withdraw from the international market, nor is it a return to the economic form and development model of self-circulation, but a timely and effective measure to consider the short-term survival and long-term development of foreign trade enterprises under the sudden incident of COVID-19 epidemic.

　　From a practical point of view, "export to domestic sales" is not only an important measure to stabilize employment and foreign trade in the "six guarantees", but also an important starting point for implementing the "six guarantees" of "ensuring residents’ employment, ensuring market players and ensuring the stability of industrial chain supply chain". According to statistics, there are more than 400,000 foreign trade enterprises in China, which directly and indirectly promote employment of about 180 million people, including more than 80 million migrant workers. Helping foreign trade enterprises is of great significance to stabilize employment, foreign trade, development and poverty alleviation in China. At the same time, "export to domestic sales" is also conducive to China’s ongoing supply-side structural reform and to promoting China’s ongoing consumption transformation and upgrading.

　　In the long run, "export to domestic sales" is conducive to the development and growth of foreign trade enterprises, especially small and medium-sized foreign trade enterprises, improve the competitiveness of foreign trade enterprises in the international market, improve the ability of enterprises to make full use of "two markets and two resources", and promote the mutual development of domestic and international double circulation. At the same time, "export to domestic sales" is also conducive to the adjustment of domestic economic structure and the high-quality development of the domestic economy. Therefore, "export to domestic sales" is not only a short-term response, but also a need for long-term development.

　　Export and domestic sales are basically two completely different models and systems. Export is a system built around order, efficiency and product quality, and enterprises rarely have their own brands. Domestic sales is a system built around consumer demand, supply chain coordination and comprehensive services, and corporate brand effect is very important. It is more difficult for foreign trade enterprises to build a new production, sales, service and accounting system in order to realize "export to domestic sales".

　　For most foreign trade enterprises, it is difficult to "export to domestic sales": first, there is a lack of brands, and most small and medium-sized foreign trade enterprises export by OEM or processing trade without their own brands; Second, lack of marketing, export-oriented enterprises mainly take orders, and basically have no marketing experience; Third, there is a shortage of talents. Most export enterprises have not been tempered in the domestic market and lack talents in market development, market operation and maintenance, and comprehensive services. At the same time, there are great differences between domestic and foreign trade in trading rules, settlement methods and enterprise management, so foreign trade enterprises must make corresponding adjustments. In addition, due to the differences in consumption culture and habits, the technical standards, design concepts and functional styles of export products are determined according to different market conditions. Many foreign trade products are not suitable for direct domestic sales, and foreign trade enterprises need to redesign according to the domestic market demand, and some even need to make necessary transformation of production lines.

　　Although there are many difficulties in "exporting to domestic market", there are also many advantages. First, the in-depth supply-side structural reform in China has provided a good opportunity for "exporting to domestic sales"; Second, the domestic expansion of domestic demand and the upgrading of consumption have provided a broad market for high-quality products that are "exported to domestic sales"; Third, the domestic policy of opening wider to the outside world and optimizing the business environment has provided a basis for sustainable development of "exporting to domestic sales"; Fourth, the guidance and support of governments at all levels provide a strong guarantee for "exporting to domestic sales".

　　"Export to domestic sales" is a long-term systematic project, which requires the cooperation and active guidance of various government departments and the enthusiastic participation and strong support of the whole society. First of all, we should create a good ecological environment for "exporting to domestic sales". All localities and departments should introduce targeted supporting measures according to the actual situation, strengthen policy guidance and business training, and publicize and promote good experiences and practices in a timely manner. Secondly, effectively solve the difficulties encountered by "export-to-domestic" enterprises, and make beneficial exploration for the smooth domestic and international double circulation. All localities and departments should make active efforts to effectively solve the bottleneck problems involved in the transformation of foreign trade enterprises, such as channels, taxation, settlement, etc., create a higher level of international and legal business environment, and open up the path of international and domestic double-cycle mutual development. Third, adhere to the principle of marketization and promote the sustainable development of "exporting to domestic sales". Encourage qualified foreign trade enterprises to carry out "export to domestic sales" in accordance with the principle of marketization, provide a level playing field for domestic foreign trade enterprises to expand the domestic market, and promote the sustainable development of various enterprises under open and transparent market rules. In short, we should design "export to domestic sales" as a long-term strategy, and plan together with the smooth domestic and international double circulation, so as to help foreign trade enterprises embark on the road of transformation and upgrading of "two incense sticks inside the wall and two incense sticks outside the wall".

　　On the evening of August 2, local time, Abderahman Chiani, leader of the military coup in Niger and chairman of the National Committee for the Defence of the Motherland, said in a televised speech that the Committee would not accept all sanctions from the Economic Community of West African States (ECOWAS), would not restore President Bazoum to his post under regional and international pressure, and would not yield to threats from any side.

△ Durahman Chiani

　　Chiani also said in his televised speech that there was no security threat in the French, Niger, and there was "no objective reason" for the French to evacuate overseas Chinese.

　　According to local media reports on the 2nd, since July 29th, Chiani has issued a number of decrees in his capacity as Chairman of the State Committee for the Defence of the Motherland and Head of State, including the appointment of eight military officers as the chief executives of eight regions respectively, and the announcement of the appointment of the Secretary-General of the ministerial government, the Director of the State Committee for the Defence of the Motherland and the Chief of the Office of the Head of State.

　　On July 26th, some soldiers of Niger Presidential Guard detained Bazoum. Late that night, the military representatives of the coup announced the establishment of the National Committee for Defending the Motherland, relieved President Bazoum of his functions and powers, and the military regime took over state affairs. Chiani announced his appointment as the chairman of Niger’s National Committee for the Defence of the Motherland on the 28th. (Headquarters reporter He Beiping)

　　Science and Technology Daily, Beijing, March 16 (Reporter Liu Xia) New Zealand scientists published a paper in the latest issue of PLoS One, saying that a new study they conducted found that since 2005, plastic pollution in the global ocean has reached an "unprecedented level". At present, about 170 trillion pieces of plastic are floating in the ocean, with an estimated total weight of 2.3 million tons. If it is not controlled, the speed of plastics entering the ocean may be several times faster in the next few decades.

　　Researchers collected plastic samples from more than 11,000 sites around the world, focusing on the situation during the 40 years from 1979 to 2019. The results show that the trend of plastics entering the ocean before 1990 was not obvious, and it fluctuated between 1990 and 2005, and then it increased sharply.

　　Lisa Edeler of the University of Auckland, who is in charge of the latest research, pointed out that there are many sources of plastic pollution in the ocean: fishing nets, buoys, discarded clothes, car tires and disposable plastics, which will eventually decompose into microplastics. In addition, at present, only a small part of plastic is properly recycled, and many plastics will eventually be landfilled. If the landfill is not properly managed, plastic waste will enter the environment and eventually flow to the ocean.

　　Edeler explained that from 1990 to 2005, the amount of plastic waste in the ocean declined in some cases, partly because there were some effective policies to control pollution, including the International Convention for the Prevention of Pollution from Ships, which came into effect in 1988, which was a legally binding agreement among 154 countries, aiming at stopping the discharge of plastic by the navy, fishing and shipping fleets.

　　She appealed that with the increasing production of plastics, countries need to formulate a new treaty, not only to reduce the production and use of plastics, but also to better manage how to dispose of plastics.

According to foreign media reports, on January 23, US time, the 20-year-old "Little King of Pop Music" and Canadian pop singer Justin • Justin Bieber was arrested in the coastal city of Miami for "holding an invalid driving license", "drunk driving" and "resisting arrest". Before his arrest this week, Bieber was exposed to spending $75,000 in a strip club.

Miami police’s inspection report confirmed that Justin Bieber was charged with drunk driving, drug abuse and speeding, and faced six months in prison.Then Bieber’s video appeared at the bail hearing and was finally released on bail for $2,500. Bieber admitted to the police that he was drinking and taking drugs that night. When asked about the source of the prescription drug, he said it was given by his mother. According to TMZ, a well-known gossip media, Bieber refused to obey the police inspection after his arrest and swore at the police.His friend Ryan Butler Twitter: Bieber called and cried and told him that he was going to disappoint his fans this time.

Bieber drunk driving test report　

Bieber was arrested by Miami police for drunk driving and drug abuse.

Raymond &bull, an official of Miami Beach Police Department; Martinez told reporters on the 23rd that at about 4 am on the 23rd, a Miami beach official saw Bieber driving a yellow Lamborghini and a red Ferrari racing car in a residential area near Miami beach. These cars were seriously speeding, driving at a speed of 55 to 60 miles per hour, while the speed limit in this area was 30 miles per hour.

A person familiar with the matter told foreign media that Bieber had drunk in a local bar and drove away, and he was racing with a friend. In order to satisfy Bieber’s desire for racing, Bieber’s team even blocked some streets. It is reported that Bieber was driving a yellow Lamborghini and his friend was driving a red Lamborghini. At present, the police have also arrested Bieber’s friend. At that time, Bieber was not only alone in the car, but also a female model as a car companion.

On the same day, 20-year-old Bieber was sent to prison for failing an alcohol test. After arriving at Miami-Dade County Prison, Justin was taken head photos and fingerprints there. Justin’s video later appeared at the bail hearing, and the bail was $2,500. Martinez said that in the inquiry record, Justin • Bieber admitted drinking, smoking marijuana and taking some prescription drugs.

It is said that Justin, who was stopped by the police, did not cooperate at first, and repeatedly asked the police why they stopped him. The arrest report described Bieber as "red in the face, bloodshot in the eyes and full of alcohol."

Bieber appeared in court to accept the charges and hired Roy Black as his representative. In the end, Bieber was released on bail for $2,500, including $1,000 for drunk driving, $1,000 for resisting arrest and $500 for expired driver’s license. Bieber admitted to the police that he had been drinking and taking drugs that night. After getting bail, Bieber sat on the roof and waved to the fans who had been waiting for him.

After Bieber was released on bail,

Spent $75,000 to watch a strip show before the incident.

Justin • Bieber became famous when he was young. Since he became popular, he has been in constant trouble, from climbing stairs at midnight to smoking marijuana and drinking alcohol, and he has made headlines in foreign media gossip every once in a while.

Justin • Bieber came to Miami to have fun this week. Earlier this week, Bieber was caught spending money at the "King of Diamonds Strip Club" in Miami, throwing $75,000 into the highest-level box and invited four favorite strippers to perform for himself.

In addition to the suspicion of drunk driving, Bieber’s plane was escorted by the police without permission after landing at O ‘Pallocca Airport in Florida this week, and the O ‘Pallocca local police station has also begun to investigate this.

In 2013, Justin • Bieber was accused of doodling on the wall of his hotel in Brazil and Australia.

In February 2013, Justin • Bieber joked with former US Secretary of State Hillary Clinton. He took a selfie and passed it on to Hillary Clinton. The "amazing move" was bombarded.

In July 2013, a video of Bieber insulting former US President Bill Clinton was exposed by the US website TMZ10. In the picture, Bieber urinates in the mop pool of a restaurant kitchen, then sprays water on a photo of Clinton and shouts "Fuck Bill Clinton". In this regard, Bieber has apologized.

On the evening of January 10, 2014, Justin threw 20 eggs at his neighbor’s apartment in Los Angeles. The neighbor was unbearable to harass the police and reported to the police that the estimated maintenance cost was $20,000, which was a felony in the local area.

Last week, the police searched Justin’s residence in Los Angeles, and a friend in his residence was arrested on suspicion of possessing drugs.

Justin • Bieber was born in Canada on March 1, 1994. He has shown great musical talent since he was a child and is regarded as the little prince of music in the world pop music scene. In 2011, Bieber was named the richest young man in Hollywood by People magazine, and was also the best-selling male artist in 2011.

From AlphaGo’s battle with Ke Jie to OpenAI’s bloody abuse of Dota2 semi-professional players, AI once again stepped onto the stage of history. Since 2012, thanks to the increase in data volume and the substantial increase in computing power due to the emergence of deep learning, artificial intelligence has begun to explode.

However, there are reports that IBM’s medical department has laid off a large number of employees, with a scale of 50%-70%; Then there was news from STAT, an American medical media. STAT got a document from Andrew Norden, then the deputy chief health officer of IBM Watson Health. The report showed that doctors who were using Watson for Oncology(Watson strong criticisms, pointing out that Watson often made inaccurate medical advice, which made IBM Watson fall into the biggest crisis of trust in history. Recently, some media surveys have pointed out that many medical imaging AI products are lying in the hospital "eating ash".

Behind the medical AI carnival is the embarrassment that new technologies frequently encounter the application of landing scenes. Is medical AI a conceptual obscenity or just a capital game? If the technical scene can be realized, then what characteristics of products can be truly accepted by hospitals and avoid the fate of "eating ash"?

At present, the development trend of artificial intelligence is unstoppable. From abroad to China, from capital giants to technology giants, the smart medical industry has been actively deployed. Medical imaging AI is highly favored by capital and is considered to be the first to be commercialized, which is expected to achieve overtaking in corners.

At present, many companies have developed products to assist doctors in different departments, which are accelerating the commercial layout. However, after the carnival from 2017 to the first half of 2018, medical AI companies did not seem to hand over a beautiful answer sheet. It is reported that there are as many as 10 medical AI companies cooperating with the Imaging Department of Run Run Run Shaw Hospital in Zhejiang.

Chai Xiangfei, CEO of Huiyi Huiying, believes that AI medical entrepreneurship is still in its infancy as a whole, and there is still much room for improvement in terms of underlying technology, product creativity and product experience. At present, there are several reasons why medical AI products lie in the hospital and "eat ash":

First, everyone has relatively high expectations for medical AI. At present, the speed requirement of AI medical care and the slow change of the medical industry are the biggest contradictions, and the overall research and development cycle is long. Medical care is a traditional industry, which has many characteristics of the original industry. For example, it may take 10 to 15 years for new drugs to be developed and commercialized, and 5 to 10 years for devices to be developed.

Second, at present, most of the products are actually tried in hospitals, and the usability and friendliness remain to be investigated, and at present, AI’s participation in clinical practice is too shallow and too little. AI company should not only design products with doctors as the center, but also integrate products into doctors’ work scenes, and also conform to doctors’ usage habits to help doctors improve diagnosis efficiency and accuracy; In addition, it is necessary to design products with patients as the center, and truly serving patients and improving their medical experience are the end points of product design, and creating easy-to-use and friendly medical AI products is the key to success. Huiyi Huiying cooperates with well-known medical equipment suppliers at home and abroad, such as GE, Philips, Qixi Medical and Medtronic, and develops customized applications for the application of medical equipment such as imaging equipment and high-value consumables, so that artificial intelligence can empower traditional medical care. For example, Huiyi Huiying provides intelligent report interpretation services to patients on the basis of existing business digital films, which has been welcomed by hospitals and patients in many aspects.

AI technology can master different professional knowledge through data training, and many business fields can benefit. The artificial intelligence medical image is to use the method of image recognition to judge the picture. There may be several kinds of data in medicine, mainly image data and pathological data, and many of them can be solved by image recognition.

Lung nodule screening is an area that most AI imaging companies focus on at present. Although AI can help to find out nodules, AI can’t give a conclusion on further benign and malignant judgment and report opinions. Moreover, the products on the market at present are mostly concentrated on pulmonary nodules, and the homogenization is serious. A top-three hospital may install more than 10 AI companies’ products at the same time, but only one or two are often used. Because there is no feedback from doctors to optimize the products of other companies, the product iteration is slow, and there is a situation of lying in the hospital "eating ash".

There are many public data of pulmonary nodules, and many data sets can be downloaded directly, so a large number of companies have developed pulmonary nodule screening products in the past two years. However, for a wider range of diseases, the research and development of AI products is difficult. It is difficult to obtain data of new diseases, and high-quality data needs experts to cooperate and label, so the research and development cycle of the whole disease AI product is long. In addition, it is not enough to identify images in medical scenes alone, and the clinical value of disease screening and auxiliary diagnosis is limited. To become an indispensable tool for doctors’ daily use, they must be involved in clinical decision-making, and doctors need AI products that can cover all medical processes.

Therefore, products that go deep into more diseases and participate in more medical processes may be supported and affirmed by more hospitals and doctors, which may be the most important competitive advantage of AI imaging companies in the future. At this point, Huiyi Huiying found a new way, reached cooperation with Tsinghua University, Peking University, Stanford University and intel, and set up a joint laboratory of artificial intelligence, hoping to cut in with image data, let AI run through the whole process of imaging department, and realize a closed-loop service from screening to diagnosis to treatment and prognosis.

In 2018, Huiyi Huiying released three commonly used mapping products for screening scenes, such as CT lung nodule detection, chest DR detection and fracture detection. Its training model not only has image information, but also adds many patients’ clinical information, test information and follow-up information. Its AI products can not only locate and label lesions, but also participate in tumor staging and classification, and can provide support for doctors’ treatment decisions.

In April 2019, Huiyi Huiying and 301 Hospital released AORTIST3.0, an artificial intelligence platform for aortic dissection, which well combined the development of new disease models with the whole process coverage of single disease. Through verification, the accuracy of AORTIST3.0 far exceeds that of conventional manual measurement, and it also provides the prognosis prediction results of aortic dilatation and composite endpoint events. The performance of AORTIST3.0 can basically reach the level of accurate judgment and prediction like 301 Hospital, which can reduce the five-year recovery of 40% to 15%, and can go deeper into the medical scene and decision-making process.

Chai Xiangfei said that medical AI has entered the second half, and AI has moved from the 1.0 era to the 2.0 era. The reason for this change is. "In the past 1-2 years, we have focused on improving the diagnostic efficiency for doctors. Today, we find that the real core of medical services is patients. It is very important to take patients as the center and open up the service chain from patients to doctors to hospitals."

At present, Huiyi Huiying is committed to building an online image center, connecting patients, hospitals and doctors, providing a digital, mobile and intelligent image closed-loop service system for the three, and trying to build a platform that can continuously incubate innovative medical services and develop in depth, trying to participate in medical treatment and prognosis follow-up links. At the same time, the most troublesome profit dilemma in the industry was broken by Huiyi Huiying’s full-chain service business model. deus ex jumped out of the curse of burning money. It is reported that Huiyi Huiying has a beautiful income report card and has been regarded as a quasi-unicorn and unicorn by the industry.

The medical field in China faces two difficult problems, one is the lack of medical resources, and the other is the unbalanced distribution of medical resources. According to the data of China Health and Family Planning Statistical Yearbook, among all medical institutions in China, there are 28,261 urban hospitals, and the number of primary medical institutions reaches 927,147, which is 32 times that of urban hospitals.

Statistics on the number of various medical institutions in China in 2016

According to a misdiagnosis data of China Medical Association, the total misdiagnosis rate of clinical medicine in China is 27.8%, among which the average misdiagnosis rate of malignant tumor is 40%, and these misdiagnosis mainly occur in primary medical institutions. The total number of misdiagnosed patients in China exceeds 5,700 every year, which is four times that of the United States.

Guo Na, co-founder and COO of Huiyi Huiying, said: The scarcity and scarcity of high-quality medical resources is a fundamental contradiction. What primary hospitals really lack is diagnostic ability, which is a scarce resource. As an inevitable starting point for graded diagnosis and treatment, artificial intelligence can enable grassroots people to enjoy homogeneous resources and services.

In this regard, Huiyi Huiying has cooperated strategically with China Telecom, China Unicom, Alibaba Cloud, Jiuzhoutong, excellent companies and teams in medical care, IT, cloud computing, big data, artificial intelligence and other dimensions, integrating various resources and its own solid technical foundation, hoping to provide a whole set of services for primary hospitals by taking the medical association as the carrier. Taking the Third Affiliated Hospital of Zhengzhou University as an example, Huiyi Huiying, based on cloud computing, big data and artificial intelligence technology, built a set of intelligent imaging center for the Women and Children’s Union Medical Association, which realized the sharing of medical imaging information and diagnostic information in the medical association, promoted the integration and sharing of medical imaging resources and imaging medical resources, and all women and children’s medical institutions in the medical association could realize the uploading and centralized management of image data, as well as the sharing and reading of image information and diagnostic reports, and finally realized the sinking of high-quality medical resources.

The Third Affiliated Hospital of Zhengzhou University is not a case. It is reported that there are dozens of cases of such medical association imaging center. Guo Na said that in order to further promote the application and popularization of medical AI in primary medical institutions and greatly improve their diagnosis and treatment capabilities, Huiyi Huiying will launch the AI-empowered graded diagnosis and treatment public welfare 100 projects recently, and first provide 100 primary hospitals with free screening services for pulmonary nodules for one year. At present, Huiyi Huiying’s lung nodule screening products can quickly locate and label the lesions, and the automatic recognition accuracy of CT lung nodules exceeds 90%, which helps doctors improve the diagnostic efficiency and reduce the rate of missed diagnosis and misdiagnosis.

Talking about starting from lung nodule screening, Guo Na said that this is based on the current national conditions and future strategic goals. On the one hand, lung cancer can be said to be the first killer of cancer in China. According to the 2013 Annual Report on Cancer Registration in China issued by the National Cancer Registry, there are about 600,000 new cases of lung cancer every year. Lung cancer accounts for 20.48% of all malignant tumors in the city and 27.05% of the mortality. It accounts for 18.05% of the incidence and 22.42% of the mortality of rural malignant tumors, and the incidence and mortality are on the rise. Pulmonary nodule screening can help primary hospitals to provide primary screening services.

On the other hand, the country is vigorously promoting the policy of graded diagnosis and treatment. The medical image cloud platform provided by Huiyi Huiying can provide a good cloud platform support for medical associations and graded diagnosis and treatment, help primary medical institutions and urban hospitals to share data and doctors’ resources, and truly realize "primary examination and superior diagnosis", which can be said to be in response to the call of national graded diagnosis and treatment.

As Chai Xiangfei said, "In the context of insufficient overall medical production capacity, the application of medical artificial intelligence to the grassroots is not only just needed at present, but also the environment is relatively mature. First, using artificial intelligence to help doctors improve the efficiency of diagnosis and liberate doctors from inefficient repetitive work; The second is to help grassroots doctors improve their diagnostic level and reduce the misdiagnosis rate at the grassroots level. Although this road is difficult to walk, we can’t quit because it is difficult. Someone has to do it, and it is valuable to do it. It is worthless not to do it. "

At present, Huiyi Huiying intelligent imaging products have entered more than 1000 hospitals and are widely used in hundreds of medical institutions. It can be said that AI+ primary medical institutions are an excellent pair of "CP", which has achieved a win-win situation for AI medical enterprises, primary medical institutions and primary patients, and has also greatly promoted the development of China’s AI medical industry.

Since the outbreak of COVID-19, Huiyi Huiying has devoted herself to product development, upgrading and implementation. Based on the overall framework of Huiyi Huiying intelligent imaging solution, the algorithm and platform were upgraded for COVID-19 epidemic, and the "Trinity" COVID-19 AI solution was launched, which was helpful for clinical work by effectively combining intelligent auxiliary screening, intelligent remote consultation and digital intelligent film to empower COVID-19 epidemic prevention and control. It has provided scientific and technological assistance to many designated hospitals and shelter hospitals in Beijing, Shanxi, Henan and other places, as well as in the center of Hubei epidemic area. The solution has achieved good feedback in clinical application. The landing application results of Huiyi Huiying COVID-19 AI solution have been reported and affirmed by the top domestic and international media, and also highly praised by the three users in the hospital.

Recently, in the face of the global COVID-19 epidemic, Huiyi Huiying developed and upgraded the artificial intelligence aided diagnosis system in COVID-19 for the rapid COVID-19 epidemic. At present, Huawei has been promoted in Germany, Russia, Thailand, South Africa, Malaysia and other 40+ countries, and has cooperated with 200+ hospitals to provide support for global epidemic prevention and control.

　　[PConline evaluation]Among the newly released Intel and AMD processors, the author Xiao Bian found that the models with K or X suffixes are often more popular among consumers on major e-commerce platforms, but in fact Xiao Bian believes that the processor models without suffix are not as high as those with suffixes, and their performance is not as strong as theirs, but in fact they also have outstanding models. Today, let’s follow Xiaobian to learn about the charm of i7-8700, i5-8600, Ryzen 7 2700 and Ryzen 5 2600.

　　I7-8700 is the second flagship model of the 8th generation Core home platform. Compared with i7-8700K, both specifications are 6 cores and 12 threads, but the frequency setting of i7-8700 is much more conservative, with the basic frequency of 3.2GHz and the maximum turbo frequency of 6 cores of 4.3GHz. The highest core frequency of a single core is 4.6GHz, while the three frequencies of i7-8700K are 3.7GHz, 4.3GHz and 4.7GHz respectively. Thanks to the lower frequency setting, the thermal design power consumption of i7-8700 is only 65W, which is very low. So is it actually a small expert in energy saving and emission reduction? We will have related tests next.

　　The i5-8600 is the second highest rated i5 of the 8th generation Core. It is designed with 6 cores and 6 threads. Compared with the older brother i5-8600K, its basic frequency is 0.5GHz lower, only 3.1GHz, while the highest core frequency and the highest core frequency are 4.1GHz and 4.3GHz, which are consistent with the i5-8600K. Therefore, its thermal design power consumption is only 65W. Compared with i7-8700, its frequency design is more conservative, and it is believed that the power consumption will be further reduced.

　　AMD released the second-generation Ruilong in April this year, but only two processors in the second-generation Ruilong have no suffixes. One is this Ryzen 7 2700, which is also the second flagship model of the second generation Ruilong. Ryzen 7 2700 has a fundamental frequency of 3.2GHz, and the highest acceleration frequency of a single core can reach 4.1GHz, with a wide span. At the same time, its TDP is only 65W, which is very surprising for an 8-core and 16-thread processor. Another surprise is that, unlike the flagship model Ryzen 7 2700X, this processor has only 200 poor reviews on the JD.COM platform. What caused consumers to abandon it? Is it performance or price? Don’t worry, xiaobian will take you to explore the answer in the actual measurement later.

　　Ryzen 5 2600 is another processor without suffix in the second generation Ruilong, and it is also a low-power processor with TDP of only 65W. Ryzen 5 2600 is designed for 6 cores and 12 threads, and is built by Grofonde’s 12nm process. The fundamental frequency is 3.4GHz, and the highest acceleration frequency can reach 3.9GHz.

　　From the chart, we can see the detailed specifications of the four processors to be evaluated today. The models on Intel side generally have higher frequency and built-in nuclear display, while those on AMD side are cheaper and open to overclocking.

　　Next, let’s take a look at the changes of these four processors compared with the previous generation.

　　Due to the change of market competition, the 8th generation Core no longer squeezes toothpaste as before. From the table, we can simply see that the 8th generation Core has improved a lot compared with the previous generation. In the face of Ruilong’s multi-core offensive, first of all, the specifications of the 8 th generation i7 and i5 are compared with the previous generation.There are two more coresAlthough there are more cores, using the updated 14nm++ process can make more cores.The frequencies of i7-8700 and i5-8600 are slightly higher than the previous generation.At the same time, the thermal design power consumption of the processor is still maintained at 65W. In addition, the three-level cache of CPU has been increased a lot to adapt to more cores. In terms of nuclear display, i7-8700 and i5-8600 use HD630 vest nuclear display UHD630, which only improves the frequency by 0.05GHz, which is better than nothing, and the memory support is also upgraded from 2400MHz to 2666MHz.

　　Although the specifications and performance have been improved so much, the starting price of i7-8700 and i5-8600 is not much higher than that of i7-7700 and i5-7600, and now the actual price is only 200~300 yuan, so there is no price increase.The 8th generation of Core is the most conscientious generation in recent years.. A detailed technical analysis on the 8th generation Core canClick here to view past articles.

　　Unlike Intel’s 8th generation Core, which was hastily launched to cope with Ruilong, the 2nd generation Ruilong is obviously the product of AMD’s plan to iterate over the 1st generation Ruilong. The product uses GF’s 12nm process to make up for the shortcomings of the 1st generation Ruilong, but the TDP is still 65W. At the same time, the smarter Precision Boost 2 acceleration technology and XFR2 dynamic spread spectrum technology are used, which can make the core of the processor run at a higher frequency as much as possible, so that the processor is still excellent in applications with poor multi-core optimization.

　　In addition to the low frequency, another area criticized by the first generation Ryzen processor is the memory delay, so the focus of AMD optimization on Zen+ architecture is the cache and memory system. L1 cache delay is reduced by 13%, L2 cache delay is reduced by 34%, L3 cache delay is reduced by 16%, and memory cache delay is also reduced by 11%. At the same time, the frequency supported by the memory controller is improved, reaching 2933MHz.

　　These targeted improvements have greatly improved the second generation Ruilong compared with the first generation Ruilong and made it more mature in more applications. Want to know the detailed technical analysis of the second generation Ruilong canClick here to view past articles..

　　After comparing the improvement of these four processors compared with the previous generation, let’s enter the actual measurement link.

　　As usual, go to the test platform first.

　　In order to make the test results more objective, in addition to the motherboard and processor,We are consistent with other accessories, and the motherboard also uses ROG HERO series motherboards from ASUS, and all of them use the latest BIOS..

AMD platform

　
Willamette

　　In terms of memory, because the highest frequency that the two platforms officially claim to support is different, the memory frequency of the two platforms is not the same.It is 2933MHz on AMD platform and 2666MHz on Intel platform.

　　Memory We use the flame gun memory optimized by Zhiqi for Ryzen. When X.M.P is turned on, it can easily reach the frequency of 3200MHz, and the adaptability of the memory is also very good.

　　When testing, the motherboard BIOS is set to the full default optimal state, and then the memory frequency is changed, and other options remain unchanged.

　　Let’s first test the theoretical performance of the processor. The following tests can detect the processor in different ways.manyThreaded computing performance and single-threaded computing performance.

　　Fritz Chess Benchmark is called chess software in Chinese. You can know your processor’s computing performance by measuring the number of chess steps calculated by the processor per second.

　　WPrime is a software that tests the computing power of computers by calculating prime numbers, and has been widely used in the performance testing of processors all over the world.

　　CPU-Z is a well-known CPU detection software, and it is the most used software to detect CPU. Its own Benchmark can accurately judge the multi-core performance and single-core performance of CPU.The version of CPU-Z adopted this time is 1.85..

　　3Dmark is a software specially designed for measuring the performance of graphics cards by futuremark Company, and it has released 3Dmark99, 3Dmark2001, 3Dmark2003, 3Dmark2005, 3Dmark2006, 3Dmark vantage, 3Dmark 11 and The new 3DMark. Now, 3Dmark is not only a software to measure the performance of graphics cards, but has gradually turned into a software to measure the performance of the whole machine. 3DMark’s test physical score can be basically calculated.Actual game performance of CPU.

　　Summary of CPU theory test:The results of this evaluation are also consistent with the previous evaluation results of Ryzen and Core para-processors. Ryzen is superior in multi-thread testing because of the higher specification of para-processors, and Core processor is stronger in single-thread testing because of its higher frequency.

　　Breakdown, in the comparison between Ryzen 7 2700 and i7-8700, i7-8700 won the chess operation and CPU-Z single-thread test, while Ryzen 7 2700 gained the advantage in the other three tests, and there was not much difference between them in the test, which can be described as a tie, diamond cut diamond.

　　In the comparison between Ryzen 5 2600 and i5-8600, because Ryzen 5 2600 has six more threads than i5-8600, four of the five theoretical tests have won, and most of them have a big lead.

　　Now that the theoretical performance of the processors is known, what is the working efficiency of these four processors in practical application? Next, Xiao Bian will test the performance of the processor in practical application with the software that everyone will use in life.

　　CineBench R15 is a convincing test system for CPU and graphics card. The Cinema 4D special effects software engine developed for film and television industry is used to test a 3D scene picture with high precision, which can support up to 256 logic cores. In addition, the new version also strengthens the investigation of shaders, anti-aliasing, shadows, lighting and reflection blur, and the detection of CPU performance is more accurate.

　　WinRAR is one of the most commonly used compression software. You all know how high it requires the performance of the CPU. The stronger the performance of the CPU, the faster it is pressed and the shorter it takes.

　　Let’s compress a 2.66GB file and see how much time they take.

　　X264 FHD Benchmark can effectively test the floating-point operation performance of CPU and the actual file-changing ability of multimedia audio and video.

　　The testing significance of POV-Ray is similar to that of CineBench R15, and it also represents the 3D rendering performance of CPU. The more pixels rendered per second, the stronger the performance.

　　Video export, like WinRAR above, consumes huge CPU resources, and friends who specialize in video have extremely strong demand for this performance. We will let them export the same video, with the same video parameters and total recording time. There will be two export formats, one is the H.264 format which is more commonly used and should be the most widely used, and the other is the H.265 format which is more efficient in updating compression but has less application scope.

　　Summary of professional software testing:Generally speaking, in the professional application software test, the four processors have their own advantages and disadvantages in the comparison, which is equally divided.

　　To break it down, let’s first look at the comparison between i7-8700 and Ryzen 7 2700. When using CPU for 3D rendering, Ryzen processor will have a greater advantage because there are more cores and threads. Although i7-8700 is stronger in single-core rendering, no one actually uses only one core for rendering, so this project is of little significance. In the aspect of audio and video transcoding, there is not much difference between them when exporting video to H264 code, and i7-8700 is slightly stronger, but i7-8700 has an overwhelming advantage when exporting H.265 code, because in the latest version of X265 decoder, Intel’s native AVX 256-bit instructions are fully optimized, while Ryzen series processors do not have the native AVX 256 instruction set. It must be split into two 128-bit instructions for execution, so the efficiency is much lower. We can see that even the i5-8600 hangs Ryzen 7 2700 in this test. In other tests, there is not much difference between the two.

　　In the comparison between i5-8600 and Ryzen 5 2600, it presents another situation, which is the same as the theoretical test result, because Ryzen 5 2600 has twice as many threads as i5-8600, and it has the upper hand in most application tests, except the H.265 transcoding mentioned above.

　　Therefore, when you buy a processor, you should look at what you will often use in your daily use. If it is 3D rendering, it is wise to choose Ryzen processor. If you often need video transcoding, i7-8700 is obviously a better choice.

　　Of course, the CPU test is inseparable from the game performance. Tomb Raider 10, Wizard 3: wild hunt, Whole Territory Blockade and Ghost Action: Wilderness are selected for the project, all of which have 1080P resolution and the highest special effects. The colorful iGame1080 Flame God of War is selected for the graphics card to ensure that the graphics card will not become a test bottleneck at 1080p resolution.

　　Summary of CPU game performance test;We can clearly see that the optimization of multi-threading in 3A masterpieces is still not very good. The performance of i7-8700 and i5-8600 is not much different, and so are Ryzen 7 2700 and Ryzen 5 2600.

　　Therefore, with higher frequency and stronger ipc, the 8th generation Core won the game performance test, but the gap between the four processors is very small.

　　Since it is impossible to test the power consumption of a certain hardware separately, the following are all the power consumption of the whole machine, which are three application scenarios. The game is fully loaded with the peak power consumption of the whole machine in the process of Tomb Raider 10》Benchmark, while the CPU is fully loaded with Prime95 running FPU baking machine test and the graphics card is empty.

　　In order to ensure the stable operation of the whole machine, we use the MVP P850 power supply of Hangjia, which has passed the 80PLUS white gold medal certification and is located at the top of the power pyramid.

　　We can see that the power consumption of Core is obviously higher than that of Ruilong. After all, the frequency of Core is also higher. Intel will officially set the maximum core frequency and the maximum core frequency of a single core, from which we can know that the full core frequency of i7-8700 is 4.3GHz and that of i5-8600 is 4.1GHz when the CPU is fully loaded.

I5-8600 baking machine

　　The same is true in the actual baking machine, but we can still see some problems. Why is the power consumption of Ryzen 5 2600 higher than that of Ryzen 7 2700? This is actually related to the processor frequency. So what’s the frequency of baking machine in Ryzen processor?

Ryzen 7 2700 baking machine

Ryzen 5 2600 baking machine

　　We can clearly see that the full-core frequency of Ryzen 7 2700 roaster is 3.425GHz, while that of Ryzen 5 2600 roaster is 3.675GHz, which is 0.25GHz higher than that of Ryzen 5 2600, so it is not surprising that the power consumption is relatively high. Therefore, we can draw two conclusions. One is that the accelerated frequency policy of Ryzen 7 2700 will be more conservative than that of Ryzen 5 2600. The other is that for the second generation Ryzen processor, the increase of frequency is more likely to cause the increase of power consumption than the increase of core.

　　In the choice of radiator, in order not to reduce the frequency of the processor, we use the relatively high-end air-cooled overclocking three Donghai hegemony. The radiator is a 6-heat pipe dual-fan radiator, and theoretically four processors with TDP of only 65W should be enough. Let’s take a look at the temperature performance of the four processors under this radiator. The room temperature was 25 degrees Celsius during the test.

　　With the same radiator, the Ryzen 7 2700 with the most cores but the lowest frequency has the best performance. No wonder Acer has stuffed the Ryzen 7 2700 into the notebook, and the excellent temperature performance of Ryzen 7 2700 and Ryzen 5 2600 is also very suitable for DIYer to buy them to assemble high-performance ITX hosts. Let’s take a look at Intel again. Although the thermal design power consumption of the i5-8600 and the i7-8700 is 65W, it can be seen that the temperature difference between them is quite obvious. The performance of the i5-8600 is still normal, while the i7-8700 has a core-wide maximum frequency of 4.3GHz consistent with the i7-8700K, and the temperature reaches a relatively high of 87.Therefore, users who choose i7-8700 should pay attention not to neglect the purchase of radiator just because its thermal design power consumption is only 65W..

　　Based on the above performance tests, including 16 tests of theoretical performance, professional application performance and game performance, we can get the following comprehensive performance ranking chart.

　　I7-8700 won the battle between the second generation Ruilong and the eighth generation Core flagship with a slight advantage, while Ryzen 5 2600 helped the second generation Ruilong regain a city. Of course, our tests in this paper are all carried out at the default frequency, while Ryzen series processors are all frequency-unlocked. In the previous first test of the second generation Ruilong, we have tested that the overclocking ceiling of the second generation Ruilong is between 4.2 and 4.3 GHz, and the performance of Ryzen processor after overclocking is also acceptable.Click here to view past articles..

　　This is the ranking of the four processors in this paper in our new version of PConline CPU ladder diagram. The above picture is a brand-new interactive CPU ladder diagram released by PConline, which includes linked e-commerce price, related original articles, parameter comparison, ranking comparison and performance comparison. Users who need it will collect it soon, and there will be ladder diagrams such as graphics cards and notebook processors released one after another in the future.

　　The PC side canClick here to jump.

　　On the mobile side.Click here to jump.

　　Let’s summarize the situation at Intel first. Because i7-8700 has the same full-core turbo performance as i7-8700K, the performance difference between them at the default frequency will not be very big. Moreover, due to the rising specifications of the 8th generation i7, the heat and power consumption are relatively high. In other words, the cost of overclocking i7-8700K on the radiator, power supply and motherboard will be relatively high. For consumers who are not very keen on the ultimate performance, i7-8700 that can be used with B360 motherboard is undoubtedly a better choice.

　　As for the i5-8600, because of its high pricing, its performance will not be very outstanding compared with Ryzen 5 2600 or its younger brother i5-8500/8400, and its power consumption is also high, and its temperature is high. Xiaobian thinks that the purchase value of this processor is relatively low.

　　On the AMD side, we can see from the above evaluation that Ryzen 7 2700, the sub-flagship, actually has its own advantages in comparison with the 8th generation Core sub-flagship i7-8700, so why is its sales volume so low? This can only blame its big brother Ryzen 7 2700X. Ryzen 7 2700X has stronger performance, and a new belief RGB ghost radiator is presented, but it is only 200 yuan more expensive than Ryzen 7 2700, and most consumers will choose the flagship Ryzen 7 2700X with higher standards. Nevertheless, we can still see an outstanding advantage of Ryzen 7 2700, that is, excellent temperature and power consumption performance, which will be particularly prominent in notebooks or when building ITX hosts. We can expect more manufacturers to directly put this processor into notebooks in the future. However, there are only a few consumers with this demand. We can also foresee that if AMD does not further adjust the price of Ryzen 7 2700, the audience of Ryzen 7 2700 will be very small for a long time to come, and the sales volume will not change much.

The radiators of Ryzen 7 2700 and Ryzen 5 2600 are different, and the materials are better.

　　As for the Ryzen 5 2600, it has gained the upper hand compared with the i5-8600, and it also has certain advantages in temperature and power consumption. More importantly, the Ryzen 5 2600X, which is 200 yuan more expensive than it, does not give away the temptation to believe in the RGB ghost radiator, so this processor has a fair sales volume. When it comes to overclocking, Ryzen 5 2600 can easily exceed 4,0GHz, but whether it can exceed 4,2GHz depends on the face. Although it is 200 yuan cheaper than Ryzen 5 2600X, the highest acceleration frequency of Ryzen 5 2600X single core can reach 4.2GHz. If the temperature and power consumption are not too high, Xiao Bian still recommends everyone to buy Ryzen 5 2600X.

　　In the choice of Ruilong and Core processors, it is necessary to choose according to the needs of the readers. For example, it is more wise for netizens who often use 3D renderers who are very concerned about the temperature of power consumption or to use Ryzen 7 2700 or Ryzen 5 2600 naturally, but for consumers who often need video transcoding, especially H.265 format transcoding, it is more efficient to use i7-8700. Of course, what we discuss in this paper is based on the price of JD.COM’s self-operated platform on July 13th. If the original price of i7-8700 is three or four hundred more expensive than that of Ryzen 7 2700X, its purchase value will be greatly reduced.

These days, citizens should find that the "health code" in our city has recently added the function of scanning code. Recently, according to the requirements of the municipal epidemic prevention and control headquarters, the code scanning operation of "health codes" in key places and key units was carried out throughout the city to further improve the accuracy of epidemic prevention and control, strengthen the traceability and monitoring of the epidemic, and better protect the lives and health of the broad masses of the people. After adding the code scanning function, aiming at the main problems that citizens may encounter in their daily use, the Municipal Big Data Center released the practical 30 questions and 30 answers of Tianjin "health code" yesterday to help citizens successfully unveil the mysterious "veil" of Tianjin "health code".

Citizen bright code+scan code: there are four ways to choose from.

1. How to scan Tianjin "health code"? Is there any change from the previous channel of bright code?

A: There is no change. You can continue to use it according to the original bright code channel. At present, Tianjin’s "health code" has four channels, such as "Jinxin Office" APP, "Jinxin Office" WeChat applet, "Jinxin Office" Alipay applet and Alipay homepage Tianjin "health code", and any one of them can be displayed normally. After opening the bright code page, you will find that there is a veil on the QR code while displaying the code color and COVID-19 vaccination logo "Jindun". Click the prompt "Please scan the venue code" on the veil, and use the camera to scan the "venue code" posted in the upcoming venue.
