　　Improve the acceptance system of letters and visits. Discipline inspection and supervision organs at all levels should enhance their political awareness, overall awareness and sense of responsibility, and seriously accept reports, complaints and appeals involving party member, party organizations and administrative supervision objects. Problems that harm the vital interests of the masses should be taken seriously, and no prevarication or perfunctory. Responsible persons of discipline inspection and supervision organs at all levels should always read letters from the masses and receive regular visits from the masses. Local discipline inspection and supervision organs should go deep into the grassroots to receive the masses. On the premise of ensuring security and confidentiality, we will gradually promote online reporting and broaden the channels for accepting letters and visits.

　　Improve the letter handling system. Establish and improve the rules and regulations such as receiving registration, sending for examination and approval, transferring to reminders, investigating and closing cases, replying to letters and returning visits, filing and filing, and promote the standardization and proceduralization of letters and visits.

Establish and improve the emergency response mechanism for group visits, clarify the responsibilities of relevant leaders and departments of discipline inspection and supervision organs, and strengthen coordination and cooperation with relevant units and departments through information notification and joint meetings. When there is a major group visit, in accordance with the principle of "who is in charge, who is responsible" and "territorial management", the leaders and staff of relevant regions, departments and units should immediately rush to the scene, actively guide and properly handle it. It is necessary to enhance foresight and formulate work plans for possible problems in mass petitions. Decisive measures should be taken to deal with acts that seriously disrupt the order of letters and visits. For major repeated group visits, it is necessary to analyze the causes, and pay attention to investigate and deal with possible violations of discipline and law by a few party member cadres. Establish a regular investigation system to investigate key visitors, signs of collective visits and unstable factors, and solve them on the spot in time. At the grass-roots level, collective visits that have a great influence and reflect the infringement of group interests can attract representatives of the masses to participate in the investigation after approval.

　　Improve the reporting telephone handling system. Answer the phone call patiently, make records, repeat the important information and circumstances to the reporter for confirmation, and explain or reply to the reporter according to the policy. Report the urgent and important situation to the leaders in time, and take measures to deal with it quickly.

For letters and visits involving group interests and major and complicated issues, the results of the investigation can be fed back to the informants in a certain range through appropriate means. When necessary, the relevant organizations or personnel may be required to be present to explain the situation, and a hearing may be held if conditions permit.

If the accuser or accuser has justified reasons to ask the relevant staff to withdraw, the accepting organ shall make a decision on withdrawal. Gradually establish and improve the reward system, and reward meritorious personnel who report and accuse major violations of discipline and law.

　　Safeguard the legitimate rights of the accused and accused. It is necessary to explore measures and methods to safeguard the rights of the accused and accusers, take seriously the explanations or explanations of the accused and accusers, and attach importance to the reports and accusations of the accused and accusers against the disciplinary violations of the discipline inspection and supervision organs and their staff. The contents of the report that have not been investigated or are under investigation shall not be leaked or spread. After investigation, it is not found that the accused or accuser has disciplinary problems, and when necessary, he can inform the situation within a certain range, clarify the right and wrong, and eliminate the influence. Those who falsely accuse should be punished in strict accordance with discipline and law.

　　Ensure the smooth channels of appeal.

Do not meet the appeal conditions, should inform the complainant. It is necessary to establish a joint meeting system for letters and visits, trials and other departments, strengthen communication and coordination, timely study and deal with outstanding problems in appeal review, and solve difficult and complicated appeal review cases.

　　Four, guide the masses to report letters and visits in an orderly manner according to law.

Advocate the implementation of a two-way commitment system, the accepting organ promises to deal with letters and visits in a timely manner according to law, and the complainant promises to maintain the order of letters and visits. For letters and visits that have been or should be solved through legal channels such as litigation, arbitration and administrative reconsideration according to law, and that should be accepted by other units or departments, the units or departments that accept letters and visits should be informed. For a few who hinder the order of letters and visits, criticism and education should be carried out. In violation of public security regulations, it is necessary to coordinate the public security organs to deal with them according to law.

　　Standardize the petition reporting behavior of party member and the staff of state organs. Party member, the staff of state organs should report and accuse responsibly in accordance with organizational principles and legal procedures, and lodge complaints realistically, and shall not distort or fabricate facts, falsely accuse or frame up.

　　Five, strengthen the management and supervision of letters and visits and staff.

　　Strengthen internal management. Formulate internal centralized management measures for letters and visits, and gradually realize the unified acceptance, transfer and management of letters and visits by the letters and visits reporting department. For the letters and visits diverted to other departments of this organ, the letters and visits reporting department should grasp the handling situation and summarize and analyze it regularly. Establish and improve the handling and management system of letters and visits, and strictly implement the examination and approval procedures for letters and visits that need to be sent or directly investigated. Regular reminders and supervision of letters and visits, reminders and supervision of major and difficult cases should formulate plans and organize their implementation after approval. The results of handling letters and visits reported by lower authorities should be strictly examined, and if necessary, they can be reviewed or directly investigated.

　　Strengthen supervision and restriction. Establish and improve the collective investigation mechanism of case clues, and the leaders of discipline inspection and supervision organs organize the heads of discipline inspection and supervision offices, letters and visits offices and other departments to jointly study and handle opinions. The complaint reporting department should have a reasonable division of labor, and form a mutual restraint mechanism of acceptance, handling, supervision, audit, closing and filing. Petition reporting staff should be rotated regularly. Gradually establish an external supervision mechanism, attach importance to the masses’ reflection on handling complaints and reports in violation of discipline and law, and severely deal with offenders. The discipline inspection and supervision organs at higher levels should strengthen the supervision and inspection of the handling of letters and visits by subordinate organs according to discipline and law, and correct the existing problems in time.

　　Strict accountability. Establish and improve the main leaders of the discipline inspection and supervision organs to take overall responsibility, and take charge of the leaders, letters and visits, reports and other departments and their staff members. Gradually implement the fault investigation system for reporting letters and visits. For those who lose, conceal or destroy the reporting materials without authorization, who are perfunctory and buck-passing, which leads to repeated letters and visits, collective visits or intensified contradictions, who leak the reporting information of letters and visits, which leads to the investigation and handling of cases being blocked or reported, and the complainant being retaliated, who do not deal with important letters and visits and unexpected events in time and cause serious consequences and adverse effects, and who have other dereliction of duty, they should distinguish their responsibilities and deal with them seriously in accordance with party discipline and discipline. If the case constitutes a crime, it shall be transferred to judicial organs for handling.

　　Discipline inspection and supervision organs at all levels should attach great importance to standardizing the work of letters and visits according to discipline and law, earnestly strengthen leadership, carefully organize and make careful arrangements. According to the actual situation, we should determine the focus of work at different stages and advance it step by step. It is necessary to strengthen investigation and study, grasp the new situation, solve new problems, and ensure that the tasks and requirements of standardizing the work of letters and visits according to discipline and law are implemented.

　　According to the China Meteorological Bureau

　　News of tornado key open laboratory

　　On the afternoon of April 27th.

　　A tornado occurred in Zhong Luotan Town, Baiyun District, Guangzhou.

　　A number of netizens in Baiyun District of Guangzhou said

　　April 27th at about 3 pm.

　　The sky outside the window suddenly turned black.

　　According to @ Guangzhou Weather this afternoon,

　　Judging from the data from meteorological monitoring

　　A tornado is suspected in Baiyun Zhong Luotan.

　　The staff is going to the scene for investigation.

　　Post details later.

　　Tornado is a strong, small-scale air vortex, which is produced by strong convective movement of air under strong unstable weather conditions, and often goes hand in hand with strong convective weather systems such as thunderstorms, hail and heavy rain. As a kind of strong convective weather, tornado can be said to be the most violent weather phenomenon caused by convective storm. Tornadoes are divided into 0-5 enhanced Fujita series, that is, EF0 to EF5, according to their different damage degrees.

　　How to deal with:

　　1. The safest place to avoid a tornado is an underground space or place;

　　2. When encountering a tornado outdoors, you should quickly run in the vertical direction of the moving direction of the tornado and lie on the low-lying ground, ditches, etc., but stay away from trees, telephone poles, billboards, fences, etc. to avoid being smashed, crushed or electrocuted.

　　3. If you are in a car, you should leave in time, because the car itself has no ability to defend against tornadoes. Once the car and people are rolled up by tornadoes at the same time, the harm is even greater.

　　Radar monitoring system shows that

　　The report of the 19th National Congress of the Communist Party of China pointed out that China’s economy has changed from a high-speed growth stage to a high-quality development stage, and it is in the key period of changing the development mode, optimizing the economic structure and transforming the growth momentum. Building a modern economic system is an urgent requirement for crossing the barrier and a strategic goal for China’s development.

　　Development is a constantly changing process. The development environment, development conditions and development concepts will not remain unchanged. The development concept of innovation, coordination, green, openness and sharing is formed on the basis of profoundly summing up the development experience and lessons at home and abroad and analyzing the development trend at home and abroad. It is also put forward in view of the outstanding contradictions and problems in China’s development, which reflects our party’s new understanding of China’s development law. When China’s economy turns to a high-quality development stage, we must thoroughly implement the new development concept, promote the quality change, efficiency change and power change of economic development, and continuously enhance economic innovation and competitiveness.

　　Innovation is the first driving force to turn to high-quality development. Under the new normal of economic development, China’s economy has changed from extensive high-speed growth mainly relying on increasing the consumption of material resources to intensive growth mainly relying on technological progress, improving management and improving the quality of workers. In the process of this transformation, China has become the second largest economy in the world. Due to the huge economic volume and the weakening of the supporting power of high-speed economic development, China’s economic development will inevitably turn to quality reform and benefit from quality. Grasping innovation will seize the "bull’s nose" that affects the overall economic and social development. To establish the concept of innovation and development, we must put innovation at the core of the overall development of the country, constantly promote innovation in theory, system, science and technology, culture and other aspects, and make innovation a strategic support for building a modern economic system.

　　Coordination is the inherent requirement of turning to high-quality development. Coordination is not only a means of development but also a goal of development, and it is also a standard and scale for evaluating development. It is the unity of two-point theory and key theory of development, the unity of balance and imbalance of development, and the unity of development shortcomings and potential. To turn to high-quality development and deepen supply-side structural reform, the focus must be on the real economy, and the coordinated development of the real economy is the premise and foundation for continuously promoting the quality improvement of the supply system. Coordinated economic development should not only solve the difficult problems in the process of structural reform, but also consider consolidating and planting the original advantages; We should not engage in egalitarianism, but also pay more attention to the balanced allocation of resources; It is necessary to fill the shortcomings of the economy towards high-quality development, but also to continuously enhance the development stamina. Solve the problem of unbalanced development in coordinated development and promote the continuous improvement of the quality of the economic system.

　　Green is the proper meaning of turning to high-quality development. Meeting the people’s growing needs for a better life is the starting point and the end result of development. Green development is the proper meaning for China’s economy to turn to a high-quality development stage, a necessary condition for sustainable development and an important embodiment of people’s pursuit of a better life. Green development is to solve the problem of harmonious coexistence between man and nature. Man is born of nature, and there is a symbiotic relationship between man and nature. Human development activities must respect, conform to and protect nature. To develop for the people, we must do a good job in the top-level design of ecological civilization construction which is related to the sustainable development of the Chinese nation. High-quality development is the development of saving resources and protecting the environment. Supported by green development mode and lifestyle, it takes the high-quality road of production development, ecological prosperity and good ecology.

　　Openness is the only way to turn to high-quality development. With the continuous improvement of comprehensive national strength, China is increasingly approaching the center of the world stage. To achieve high-quality economic development, China must adhere to the construction of a new open economic system, which requires establishing the concept of open development, making full use of advanced scientific and technological achievements and beneficial management experience created by human society, conforming to the trend of China’s deep integration into the world economy, pursuing an open strategy of mutual benefit and win-win, adhering to the coordination of internal and external needs, balancing import and export, paying equal attention to "bringing in" and "going out", attracting investment and attracting technology and wisdom, developing a higher-level open economy, and actively participating in global economic governance and public goods supply.

　　Sharing is the essential requirement for turning to high-quality development. Improving people’s livelihood and well-being is the fundamental purpose of development. In practicing the concept of shared development, it has rich connotations to realize the transition of China’s economy to a high-quality development stage. First, high-quality development should be shared by all people. High-quality development is the development shared by all, and it is not shared by a few people or some people. Second, high-quality development is comprehensive sharing. High-quality economic development will inevitably bring about political, cultural, social, ecological and other aspects of development and change, and high-quality economic development will share the achievements of national economic, political, cultural, social and ecological civilization. Third, high-quality development is co-construction and sharing. High-quality economic development requires the joint efforts of all people, and joint construction can only be shared, and the process of joint construction is also a process of sharing. Fourth, high-quality development is gradual sharing. The development of everything is a gradual process, and the sharing in high-quality development will also have a process from low to high, from unbalanced to balanced. Even if the quality of China’s economic development reaches a high level, it will be different.

　　Development is the basis and key to solve all problems in our country. High-quality development is a key link in building a modern economic system. We must unswervingly implement the development concept of innovation, coordination, green, openness and sharing, stimulate the creativity and development vitality of the whole society, solve the development problem of insufficient imbalance, push China’s economy from high-speed growth to high-quality development, and continuously expand China’s economic strength and comprehensive national strength to meet the people’s growing needs for a better life.

　　Recently, the 25th "May 4th Medal for Chinese Youth" was announced. As outstanding representatives of contemporary youth, 34 medal winners and 20 advanced collectives have integrated their personal ideals and pursuits into the development of the cause of the party and the country, played the song of youth in the new era, and concentrated on showing the spirit of young people in the new era who listen to the party’s command and are determined to struggle, inspiring the broad masses of young people to be "the country’s greatest", making brave contributions and celebrating the party’s centennial with outstanding achievements.

　　In the new era, young people in China should draw spiritual strength from the example, shoulder the historical mission, strengthen their confidence in progress, be ambitious, be virtuous, become great talents and shoulder great responsibilities, and strive to become a new person of the times who can shoulder the heavy responsibility of national rejuvenation, so that youth can bloom brilliantly in the unremitting struggle for the motherland, the nation, the people and mankind.

　　Keep faith in the rudder and firm the course of life.Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has made friends with the vast number of young people many times, expressed his confidence, paid attention to the growth of young people, gave encouragement and hope to young people, and emphasized that "the buttons of life should be buckled from the beginning". If the younger generation has ideals, skills and responsibilities, the country will have a future and the nation will have hope. In the new era, young people should be ambitious, firmly believe in Marxism, adhere to Socialism with Chinese characteristics’s belief, uphold the confidence of the Chinese nation in the great rejuvenation of the Chinese dream, listen to the party’s words, feel the party’s feelings, follow the party, closely link the ideal of life with the destiny of the country, live up to the expectations of the party, the people and the nation, realize their personal values on the road of pursuing dreams, and achieve sunshine in their hearts, distance in their eyes and strength at their feet. Young party member should firmly establish the development thought of "people-centered", always learn from revolutionary martyrs and sages, keep up with the loyalty of "always following the Party", keep up with the firmness of "beheading doesn’t matter", keep up with the concept of "people first", properly solve the outstanding problems reflected by the masses in time, and achieve "what the people need and what they will do". We should actively practice the socialist core values, be virtuous, observe public morality and be strict with private morality, and closely combine correct moral cognition, conscious moral cultivation and positive moral practice.Consciously resist money worship, hedonism, extreme individualism and other wrong ideas, and pursue a higher, more realm and more tasteful life on the road of rejuvenating the country.

　　Raise the sail of struggle and start the journey of breaking the waves.The beauty of youth is the beauty of struggle. Comrade Li Dazhao warmly praised: "The dictionary of youth is nothing ‘ Difficulties ’ The word; The youth’s oral, no ‘ Obstacle ’ The language. " "Struggle is the brightest background of youth", whether it is the heroic sons and daughters who fought bloody battles during the revolutionary war, the intellectual youth in the era of "going to the countryside", the dream chaser who took advantage of the east wind of reform and opening up to start a business in the sea, or the young people in the new era who shoulder the great responsibility of national rejuvenation, all of them interpret that "youth is brilliant by tempering, and life is sublimated by struggle". No one’s youth is easy. There are flowers and mud in spring. Contemporary young people should be determined to work hard, keep their newborn calves strong and brave, stand up when the motherland and people need it most, do the most meaningful things in the best years, be brave to go to the grassroots with difficult conditions, the front line of national construction, and the forefront of project research, undergo exercise, increase their talents, seek up and down, forge ahead, and be young. We must dare to be pioneers, not to be passers-by, to be spectators, to be superior but not pampered, to be frustrated but not short-sighted, to make prosperity and adversity become the wealth of life rather than the burden of life, to temper our true skills in the raging fire and wind, to outline the magnificent capital youth with diligent struggle, to pave the way for national rejuvenation and contribute to the construction of the motherland.Run the relay race to realize the great rejuvenation of the Chinese nation and write a wonderful chapter that can stand the test of history and the people.

　　Paddle persistent oars and sail to the other side of the dream.Years are not old, youth is immortal; Life is at the right time, and the heavy responsibility lies on the shoulders. The young people of that era blew the horn of the times of "patriotism, progress, democracy and science" and opened a bright future for China in the pursuit of Marxist truth. The spiritual wealth precipitated by the May 4th Movement has inspired generations of young people, from the youth and sweat spilled in the reclamation of the Great Northern Wilderness and Gongqingcheng, to the strong voice of the times of "uniting and rejuvenating China" at the beginning of the reform and opening up, and to the China Aerospace Research Team, which is only over 30 years old on average but can lead the world. The vast number of young people have always been the fresh troops and commandos in China’s revolution, construction and reform, and the sons of the motherland and people have always been beating in the chests of generations of young people. The golden period of contemporary youth’s life coincides with the process of realizing the "Chinese dream", and they are the "powerful generation" who have fulfilled their long-cherished wish by themselves. They should always walk in the same direction with the development of the party and the country, actively participate in the great practice of Socialism with Chinese characteristics in the new era, make first-line contributions to scientific and technological innovation, rural revitalization, social construction and other important fields, and bravely be pioneers, pioneers and devotees in the forefront of the times. "Youth has achieved nothing in vain, and there is no sorrow in the white head." Young people in the new era have broad vision, strong adaptability and communication skills. In the face of the information age and multiculturalism, they must always be determined and carry forward. "Nail-nailing spirit ",never give up, persist in moving forward, enhance the ability of continuous learning, enhance the awareness of continuous innovation, set up actions that dare to practice, and strive to grow into a trendsetter who pushes forward the times and a relay who shoulders the heavy responsibility of the times, and continuously inject strong youthful energy into social development and national progress.

The so-called "Semi-annual Report on Hong Kong" published by the British government makes irresponsible remarks and comments on Hong Kong affairs, trying to show its influence on Hong Kong affairs, which can only be futile and will only arouse the resentment of China people.

　　　　　　 Poisoning by former Russian spies triggered a diplomatic storm between Britain and Russia

　　　　　　 The poisoning of former Russian double agents in Salisbury, England, continues to ferment, and the relationship between Russia and Britain has taken a turn for the worse. The two governments have been arguing with each other for days, and both sides have been very tough and their words have become increasingly fierce. On the 15th, the British Defence Secretary bluntly asked Russia to "go away and shut up", while on the 16th, the Russian Foreign Minister responded to the British Defence Secretary, calling his remarks "uneducated".

Russian Foreign Minister Lavrov (data map)

　　　　　　 On the 15th, the British Defence Secretary said that the poisoning incident of former Russian double agents in Britain was "undoubtedly" caused by Russia. For Williamson’s accusation, Russian Foreign Minister Lavrov made an unceremonious rebuttal in Astana on the 16th.

　　　　　　 Lavrov: "Such a handsome and lovely young man may also hope to leave something in history by his hot remarks. British Prime Minister Theresa May said that Russia ‘ Very likely ’ He is famous for taking full responsibility in the poisoning incident, so he (the British Defense Minister) wants to rely on Russia ‘ Go away and shut up ’ Be famous. I don’t understand, maybe it’s because he is uneducated. "

　　　　　　 In addition, British Foreign Secretary Johnson No.16 directly pointed the finger at Russian President Vladimir Putin. Johnson said that they believed that Putin was the behind-the-scenes indicator of the poisoning incident. Once Johnson’s remarks were announced, the Russian side immediately responded. Peskov, press secretary of the Russian President, said that the accusation made by the British Foreign Secretary against the Russian President was shocking and unforgivable, which violated diplomatic rules. He also said that Russia will soon announce countermeasures against Britain.

　　CCTV News:According to Weibo, Traffic Management Bureau of @ Ministry of Public Security, this year’s Mid-Autumn National Day holiday lasts for eight days, and the first day of the holiday coincides with the Mid-Autumn Festival. The whole country has ushered in a peak of concentrated travel, and people have returned home to visit relatives and have increased their medium-and long-distance travel. The traffic flow in areas with high vehicle density such as Pearl River Delta, Yangtze River Delta, Beijing-Tianjin-Hebei, Chengdu-Chongqing and other popular tourist cities has increased significantly. From the traffic flow of 500 important nodes of 71 expressways monitored by the Traffic Management Bureau of the Ministry of Public Security, from 18: 00 on September 28th to 18: 00 on September 29th, the traffic flow increased by 53.87% from the previous day, 37.38% from last year and 13.83% from 2021.

　　Public security traffic control departments at all levels in the country, in combination with the characteristics of people’s travel during holidays and the changes of traffic flow, plan and deploy in advance, strengthen command and dispatch, start high-level services, throw personnel and equipment to the front line to the maximum extent, concentrate police forces to strictly control key vehicles such as "two passengers and one danger" and "shifting from business to non-business" buses, heavy trucks and vans, and strictly investigate drunk driving, speeding, overcrowding, illegal manned, driving in violation of the prescribed lanes, and occupying emergency. As of 18: 00, the traffic of national expressways and national and provincial trunk highways has gradually returned to normal, and some road sections are still slow, and no road traffic accidents with more than 5 deaths have been reported.

　　It is estimated that on the 30th, the whole country will still be at the peak of traffic travel, especially as the medium and long-distance self-driving traffic gradually reaches the destination, and the traffic will continue to run at the peak around some popular scenic spots in river-crossing passages and provincial boundary passages. According to the forecast of the Central Meteorological Observatory, there will be moderate to heavy rain in eastern Sichuan, Chongqing, northern Guizhou, southwestern Shaanxi, most of Hubei and central Henan tomorrow, and there will be heavy rain in the local area. There are foggy weather in eastern Henan, southern Shandong, northern Jiangsu and northern Anhui.

　　The Traffic Management Bureau of the Ministry of Public Security reminds drivers and holiday travelers that they should know the weather and road conditions along the way in advance when driving. When driving in rainy days and passing through roads in mountainous areas and scenic spots, they should pay attention to reducing the speed and increasing the distance between vehicles, so as not to be too strong. In case of dense fog, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights to keep a safe distance. When vehicles slow down and queue up, they should pass in order, without congestion or occupying emergency lanes. There are more self-driving trips and more gatherings of friends during holidays. Don’t drive under the influence of alcohol, fatigue, speeding or distraction. Fasten your seat belt all the way, whether you are driving by car or in the front row or back row.

Lei Ruibo performs scientific research tasks in the polar regions (ChinaPhoto courtesy of Polar Research Center)

CCTV News:The icebergs in the Antarctic are majestic and magnificent, and there is a faint blue light under the white coat, which is breathtaking; The arctic ocean is frozen for thousands of miles, and the fog lock is boundless. They quietly wait for someone to cross and explore the past and future here.

It was not until 1970s and 1980s that sea ice research formed a relatively mature research system in the world, and there were less than 100 scholars engaged in sea ice physics research. In China, there are about 10 teams engaged in polar sea ice research for a long time, and Lei Ruibo, a post-80s researcher, is one of them.

As a loyal observer and researcher of polar sea ice, he has participated in the 22nd Antarctic expedition in China to carry out the wintering mission, participated in six scientific expeditions to the Arctic in China, one expedition to the Yellow River Station in the Arctic, one expedition to the ice around the Baltic Sea Lake, and served as the assistant to the chief scientist of the Arctic scientific expedition in China twice.

When he first went to the South Pole at the age of 24, Lei Ruibo never thought that this piece of ice and snow would make him devote more than ten years of research enthusiasm; At the age of 37, he served as the chief scientist assistant and captain of the ninth Arctic scientific expedition in China. He has faded from his youth 13 years ago, leaving behind the perseverance and composure of a polar expedition worker.

A coincidence, the southern guy became attached to the ice and snow.

"It is difficult for southerners to understand the snow and ice in the north, and it is difficult for northerners to understand the rain in the south." Lei Ruibo was born in a rural family in Qingyuan, Guangdong Province. He was admitted to Hohai University as an undergraduate in 2000 and entered Dalian University of Technology as a postgraduate in 2004. From the southern end of the motherland to the north, let this southern boy know what is called climate difference for the first time.

By chance when he was in graduate school in 2005, he was fortunate to be the first member of Dalian University of Technology to participate in the Chinese Antarctic expedition to carry out the wintering mission and undertake the sea ice observation mission. The trip to the Antarctic made him attached to the ice and snow, and the first turning point appeared in his life direction.

"Observing in Antarctica is a hard and lonely job, and it often depends on self-study," Lei Ruibo said. Before going to Antarctica, Professor Li Zhijun carefully guided the preparation of on-site implementation plan and taught observation experience. However, the on-site situation is changing rapidly, which requires constant exploration and practice. Due to long-term field exposure, the orange-red winter clothes he wore obviously faded and the burrs were thrown up.

At the beginning of 2007, Lei Ruibo returned to China after completing the wintering sea ice observation mission, and at the same time brought back the complete ice cycle observation data he obtained in the East Pole, which was also the first quantitative and continuous sea ice observation data obtained by China in this area.

In 2009, Lei Ruibo entered the postdoctoral workstation in polar research institute of china and engaged in sea ice research. He joined polar research institute of china in 2012 and officially became a "professional player" in polar sea ice research.

Stick to the vast and mysterious polar regions,bench to sit ten years cold

Polar region is a mysterious and little known region, and there is no ready-made cognition for reference. As a polar researcher, only by sticking to the scene can we have the opportunity to decipher this complex mechanism of change.

By combining the observation data of the ice bottom position under the ice and the snow thickness on the ice surface, researchers can accurately measure the change of ice thickness of sea ice, thus understanding the impact of global warming on sea ice. Because the ice thickness can not be accurately measured by satellite remote sensing and other means, the ice thickness has become the key to solve the climate system change.

"The bitterness of wintering is unforgettable." Lei Ruibo recalled. Injured in the wild, almost lost two fingers; It is difficult for a husband and a son to get together with their families and leave them more. Do you want to stick to it? For a long time, Lei Ruibo wavered. At the beginning of 2008, after missing two opportunities to reunite with his family during the Spring Festival, he finally got the opportunity to return to Guangdong for the Spring Festival from Dalian. Unexpectedly, rare rain, snow and freezing weather occurred that year, and traffic and power transmission were interrupted … … Seeing the plight of passengers tossing and turning all the way, Lei Ruibo secretly made up his mind to devote himself to sea ice research and fight disasters.

In 2008, after taking part in China’s third scientific expedition to the Arctic, the expedition members changed from batch to batch, and Lei Ruibo never left the Arctic. After six scientific expeditions to the Arctic, the data quality obtained by Lei Ruibo and the team has been greatly improved, and some of them are even ahead of the international level.

"The bench will be cold for ten years, and the article will not be empty." Using the polar observation data accumulated for many years and the advanced ocean numerical model, Lei Ruibo focused on scientific issues such as the mechanism of rapid reduction of Arctic sea ice and its impact on the weather change process in China, the impact of the reduction of Arctic sea ice on the export of fresh water from the Arctic Ocean to the Atlantic Ocean, and the impact of the latter on the ocean circulation. The results were published in many internationally renowned journals.

On September 26th, 2018, China’s ninth Arctic expedition team successfully returned to Shanghai. (Source: vision china)

In 2018, 37-year-old Lei Ruibo served as chief scientist assistant and captain of the sea ice team of the ninth Arctic scientific expedition in China. The expedition experienced a rare storm and snow, and even experienced unexpected situations such as dense fog and ice surface rupture. At the long-term ice station of the ninth Arctic scientific expedition in China, when both the A and B prototypes of the unattended observation system announced the success of data reception, the implicit Lei Ruibo shook hands and hugged his teammates one by one.

Academic service to the country, filling the gap in polar research

"Academics can also serve the country." Engaged in polar sea ice observation and research for ten years, Lei Ruibo has made outstanding achievements in the research and development and application of sea ice observation technology, the thermal and dynamic mechanism of sea ice and the long-term change mechanism of Arctic sea ice, and has gained a certain reputation among international peers.

"Polar investigation is highly dependent on the scientific and technological support platform. There are many gaps in the field of polar research, waiting to be filled." Just as Lei Ruibo asked himself, he grasped the international research trends, combined with national needs, and sprinted to the international level.

At present, the biggest difficulty in polar sea ice observation and research in China is that there is no ready-made equipment available and it depends on foreign countries. Lei Ruibo led the team to cooperate with foreign universities and research institutes, introduce digestion, absorption and innovation, and overcome the core investigation equipment blocked by technology; They cooperated with five scientific research institutions, including Taiyuan University of Technology, and developed the manned sea ice observation and technology completely from foreign countries to the independent research and development of unattended observation equipment and the successful application of domestic integrated automatic observation equipment. More importantly, the data obtained by these key devices can support some research directions to achieve breakthrough results.

Lei Ruibo attaches great importance to the research and development of observation technology, and cooperates with Taiyuan University of Technology to develop temperature chain buoys and material balance buoys, which are widely used in China’s Arctic exploration. As the chief engineer of the national key research and development project "unattended sea ice observation system", he led the team to tackle key technical problems, successfully developed two sets of prototypes and successfully applied them. The system plans to participate in the international MOSAiC inspection plan next year, which will greatly enhance China’s international reputation in this field.

Scientific research institutes and universities are the main bodies of scientific and technological innovation, and only by cooperating can they exert their greatest strength. Lei Ruibo’s team, together with the National Marine Environmental Forecasting Center and other cooperative units, carried out scientific investigation and research on sea-air-ice in the Arctic, which gained valuable data and experience for China to carry out scientific research in the Arctic and made positive contributions to enhancing China’s polar discourse power.

Look at the most beautiful and boundless scenery and experience the most difficult loneliness. On the road of polar scientific research, it is not only his love for the polar region, but also the five-star red flag flying in the snow that supports Lei Ruibo to stick to the square of sea ice research.

"Although science has no national boundaries, scientists have their own motherland." Lei Ruibo said that the achievements made in the field of polar scientific research are like athletes winning prizes in international competitions. At that moment, the athlete represented the motherland, and he closely linked his destiny with the motherland. (Text/Lu Tao, Liu Kefeng)

Recently, East China, North China, Northeast China and other places have continuously suffered from heavy rainfall, causing floods and geological disasters, causing heavy casualties and property losses in many places. Under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the relevant localities and departments responded and dealt with it at the first time, comprehensively compacted their political responsibilities, and implemented various flood control measures with practical actions. At present, flood control, emergency rescue and disaster relief work are carried out in an orderly manner to fully protect people’s lives and property.

On July 28th, the National Flood Control and Drought Relief Headquarters launched a three-level emergency response to Beijing, Tianjin and Hebei, and three working groups sent by the National Flood Control Office have been sent to the three provinces and cities to help guide the flood control and disaster relief work. The National Disaster Prevention, Mitigation and Relief Committee launched the national four-level emergency response to disaster relief. The National Development and Reform Commission urgently arranged for the central budget to invest 50 million yuan to support Hebei’s emergency recovery after the rainstorm and flood disaster.

On the 28th, the Beijing Flood Control Headquarters launched the city’s first-level emergency response to flood control. The school stopped all offline teaching activities and field teaching activities, closed all scenic spots, parks and forest farms, and evacuated threatened tourists. Tianjin Planning and Natural Resources Bureau and Tianjin Meteorological Bureau jointly issued meteorological risk warning of geological disasters.

Relevant rescuers have arrived at the scene to search and rescue the missing persons.

　　[PConline evaluation]Now, it has been one month since Intel released the third generation Core i5/i7, and the replacement process of the old and new handover seems smooth. Intel Core i5 3450, as a new younger brother in the i5 series, is used to replace the original Core i5 2300/2320/2400 market. Recently, however, AMD quietly lowered the price of the flagship model processor FX-8150 to 1300 yuan, and the Core i5 3450 was attacked head-on. In the face of strong enemies, can Core i5 3450 cope?

● Market positioning of ●Intel Core i5 3450

　　Intel Core i5 3450 belongs to the third-generation Core i5 series. According to Intel’s plan, it is used to replace the second-generation Core i5 2300/2320/2400. The price is in the early thousand yuan, and it mainly focuses on the thousand-yuan market.

Core i5 3450 focuses on the thousand-yuan market.

　　The main difference between Intel Core i5 3450 and Core i5 3570K is that the former can’t overclock, except for the difference in frequency. However, with P67/Z68/Z75/Z77, four additional octaves can still be obtained.

● competitors of ●Intel Core i5 3450?

　　Before Ivy Bridge was released, Intel Core i5 had no competitors at the price of 1,000 yuan. But recently, AMD’s eight nuclear bulldozer has gone through several price dives and reached the price of 1,300 yuan, directly competing with Intel Core i5 3450. Who wins and who loses? We will reveal it in this PK.

AMD FX-8150 directly impacts Intel Core i5 3450.

● Analysis of ●Core i5 3450 specification

　　Core i5 3450 adopts 22nm process and is designed based on Ivy Bridge architecture. It is native with four cores and four threads, and the default frequency is 3.1GHz, which can be turbo-charged to 3.5Ghz, with 6MB of three-level cache. The core graphics card is integrated with HD2500, the default frequency is 650-1150MHz, 6MB L3 cache is shared with CPU, and the thermal power consumption of TDP is designed to be 77W.

Intel Core i5 3450　　picture　　series　　evaluating　　forum　　quote　　Net purchase price

　　For more detailed specifications, we can refer to the following table, and compare Core i5 2300, Core i5 3450, Core i5 2500K and Core i5 3570K together:

　　It can be seen that the frequency of Core i5 3450 and Core i5 2300 is 0.3GHz higher than that of Core i5 2300, and the core frequency amplitude is also a complete four octaves (Corei5 2300 has only three octaves). In contrast, the specification of Core i5 3450 is closer to that of Core i5 2500K. However, because it doesn’t support hyper-threading technology, the whole series of Core i5 is four cores and four threads. Facing the impact of the competitor FX-8150 with four modules and eight threads, does i5-3450 have a chance of winning? Next, let’s start testing.

2. Introduction of evaluation platform and method description

　　Some time ago, we have tested the performance of the core graphics card of Core i5 3450, so this paper only tests the CPU part, and will not repeat it. If you want to know this information, you can clickhereRefer to the previous evaluation articles.

　　The object of this evaluation is Core i5 3450, which is used to replace Core i5 2300/Core i5 2400 series; We add Core i5 2300, Core i5 2500K, Core i5 3570K and FX-8150 for comparison. The evaluation items include theoretical multithreading performance test, common software test, professional application test, game test, power consumption test and overclocking test.

　　In the mid-to high-end market, there is also E3-1230 V2, which has been popular recently, but strictly speaking, it does not belong to the desktop platform products under normal channels, so we will not compare it here. For the performance of E3-1230 V2, you can click.hereLearn more.

3.5、Game performance evaluation

　　In the game testing part, we selected StarCraft II: Wings of Freedom, Grand Theft Auto 4: Chapter of Freedom City and resident evil 5 for testing. Although they are not the latest games, they put high demands on the CPU, and the test results can better reflect the game performance gap between the CPUs.

● DX9 game StarCraft II:

Resident evil 5 test scores.

　　Test summary:Compared with two generations of Core i5 2300, Core i5 3450 in the game test still keeps ahead. It can be seen that Ivy Bridge has indeed made progress compared with Sandy Bridge, but in the face of scores of hundreds of frames, the gap of 10 frames is actually not obvious. FX-8150′ s test in these two rounds is more tragic, because at this stage, the game has limited optimization of multi-core, and the test is actually the performance of single core.

3.6 Platform power consumption test

　　Because the individual power consumption of CPU can’t be accurately measured in general environment, we test the power consumption of the whole platform in the power consumption test part. By investigating the power consumption gap of each platform, the power consumption gap of each CPU is indirectly reflected. We chose the famous baking machine software Prime 95, and adopted the Large mode to make the CPU and memory work at full load, while the graphics card was not at full load, and then recorded the readings on the power consumption meter.

Test of baking machine with Prime 95

Comparative evaluation of platform power consumption — — Standby (The graphics card is in standby state.)

Comparative evaluation of platform power consumption — — Fully loaded (The graphics card is in standby state.)

　　Because of the Turbo function, the power consumption of the four Core i5 products in standby state is basically the same, and the difference between them is mainly reflected in the full load state. It can be seen that the full-load power consumption of Core i5 3450 is about 10 watts lower than that of Core i5 2300. As for competitors, the power consumption brought by FX-8150 with four modules and eight cores is still very large.

3.7. Free lunch! Overclocking Test of Extra Quadruple Frequency of Core i5 3450

　　As mentioned earlier, Core i5/i7 (non-K series) with P67, Z68, Z75 and Z77 motherboards (other models are not available) can be overclocked in a small range, with an amplitude of 4 octaves. So weDirectly increase the frequency of Core i5 3450 by four times in the BIOS, set it successfully and enter the system directly. At this time, the frequency is 3.5-3.9GHz (single core turbo frequency is 3.9GHz, quad core turbo frequency is 3.7GHz):

BIOS setting method

　　The above is the motherboard used in this test — — Screenshot of BIOS settings of ASUS Saber tooth Z77, the setting path is "Advanced Processor Settings CPU Power Management", in which a default value of CPU ratio is 35 (the highest turbo frequency of i5 3450), and we set it to 39, which successfully booted up and entered the system. Let’s take a look at how much performance improvement is brought by these four extra frequency doubling.

　
3DMark Vantage test: improved by 14%

3DMark 11 test: increased by 11%

Fritz Chess test: increased by 12%

WPrime test: increased by 11%

　　Summary:After four times of frequency doubling, the average performance of Core i5 3450 is improved by 12%, which is higher than Core i5 3570K at the default frequency, and the system runs very stably. We believe that this CPU still has a lot of room for overclocking. Later, we tried to increase the frequency by five times and set the CPU ratio to 40. As a result, it will be reset after each setting. It seems that Intel’s restrictions on overclocking are still very strict, so we can only choose the "K" series model if we want to overclock.

4. Summary of PConline Evaluation Room

　　Some time ago, we have tested the performance of the core graphics card of Core i5 3450, so this paper only tests the CPU part, and will not repeat it. If you want to know this information, you can clickhereRefer to the previous evaluation articles.

CPU performance ranking, based on the CPU score of 3DMark Vantage
(For reference only, it does not represent the comprehensive performance of CPU)

●CPU performance replaces Core i5 2300 without pressure, which is similar to FX-8150 and i5 2500K at the default frequency.

　　We convert the scores of each sub-item in the previous CPU performance test into percentages based on i5 2300, and then take the average value to get the following figure:

CPU performance comparison

　　The performance of Intel Core i5 3450 is 14% higher than that of Core i5 2300. Apart from the architectural advantages, the increase of core frequency is also one of the reasons for this difference, because Core i5 3450 was originally planned to replace two series of Core i5 2300/2400. Even so, the Core i5 3450 will not impact the products of the previous level, and its performance is basically the same as that of the Core i5 2500K at the default frequency. Look at the competitor FX-8150 again, and the comprehensive performance gap between them is almost negligible.

● Power consumption control is still eye-catching

Power consumption comparison

　　The power consumption of Core i5 3450 based on 22nm process is well controlled. Although the turbo frequency is 0.4GHz higher than that of Core i5 2300, the overall power consumption is still great. This aspect has always been the strength of Intel Core series, far ahead of competitors.

　　In terms of price:Same as FX-8150.

　　The original task of Intel Core i5 3450 is to replace the Core i5 2300/2400 series. Compared with the previous generation, the CPU performance is improved by about 10%, and it will not impact the previous product, so it is not a big problem to successfully take over the market. On the other hand, AMD’s FX-8150 has suddenly cut its price to 1300 yuan recently, which has a great impact on the i5 market.From the test results, the two have their own advantages and disadvantages, but Core i5 is far from the opponent in power consumption control.

2. User groups

　　Mid-to-high-end gamers and users who have certain requirements for performance.

Step 3 buy suggestions

　　If you focus on games and multimedia entertainment, Intel Core i5 3450 is a good choice, because at present, the game is not optimized for multi-core performance, and the four-core four-thread and Ivy Bridge architecture are enough to cope with it. Intel’s advantages in architecture and power control are still obvious; If you want to overclock, you can consider FX-8150. The price reduction of the eight-core bulldozer has been within a reasonable range.
