With my own dim light, gather the vast expanse of stars. The most beautiful appearance of a scientific and technological worker is to integrate his youth, enthusiasm and wisdom into the national development needs, meet the needs of the times and solve the country's urgent problems. On May 30, the Sixth National Science and technology workers' day came. The China Association for science and technology held a symposium on the combination of online and offline. Many representatives of science and technology workers expressed their aspirations of "innovation and self-reliance" and offered suggestions for strengthening the country through science and technology. Zhaoweisheng, executive vice president of Graduate School of Beijing University of Aeronautics and Astronautics: Relying on imported scientific instruments means building pavilions in the air In particular, I would like to put forward suggestions on vigorously promoting the independent control of scientific instruments and realizing the self-reliance and self-improvement of science and technology. China has promulgated the law on scientific and technological progress, which has repeatedly emphasized the independent control of scientific instruments. I have a deep understanding of this. In 2018, due to the failure to purchase imported scientific instruments smoothly, I experienced the darkest moment in my life - the laboratory stagnated for more than half a year, every day there were problems such as the cancellation of orders for imported equipment, the stuck test equipment in the customs of various countries, and the suppliers' exorbitant asking prices, which made me deeply realize that only when scientific instruments are independently controllable, can we truly achieve self-reliance and self-improvement in science and technology. Under this tremendous pressure, we raced against time and finally independently developed the magneto-optical Kerr instrument, which is the most important to us and the most severely jammed. Now we are not only using this instrument, but also supplying other scientific research institutions to help them solve the instrument problems. On the Sixth National Science and technology workers' day, I have an initiative: take the utilization rate of domestic equipment as a core application indicator for applying for national projects. This is because today we rely on imported equipment to build towers in the air, which may collapse at any time. I suggest that the whole society should promote the use of domestic scientific research instruments. Ouyang Ziyuan, academician of the Chinese Academy of Sciences: Innovation is difficult, but Chinese people must have strong confidence Innovation is to stand on the shoulders of giants and find new solutions or solutions to difficult problems, which is very difficult and arduous work. Take my own experience as an example: I first studied geology and wanted to find a mine after graduation, but the University asked me to be an associate doctoral candidate of a Soviet expert. I am a communist and subject to the distribution of the state. However, my Soviet tutor wanted to return to China, so I had to take the associate doctoral examination again and was admitted to the Institute of geology, Chinese Academy of Sciences. At that time, I studied iron ore and copper mine, but the director said, "you can work with me on nuclear geology." But I don't have any foundation and I don't know about atomic nuclei. Two years later, I returned to the Institute of Geology and was immediately arranged to find a place suitable for underground atomic bombing. At that time, I had no idea: "I haven't done this before!" But one leader said, "no one in China has done it. Don't you young people know how to learn while doing it and finish it?" It seems that a stream of heat rushes into my head, and a strong driving force is pushing me. I immediately took 16 people out of the field, experienced difficulties and successfully completed the task. In 1957, the first man-made earth satellite was launched, announcing the arrival of the human space age. I believe this is the common goal of mankind, and China will certainly achieve it. We will build rockets, missiles, spaceships and satellites. But what do you do on the moon? What problems are worth studying? Mars? Nobody did this. "I'll do it!" From the beginning of studying various meteorites, I slowly trained a team and established a laboratory. In the field of lunar exploration, we have made a total of 35 years of basic preparation, and passed 10 years of demonstration. In 2004, the State Council approved China's lunar exploration plan, and I served as the chief scientist. Innovation is very difficult, but we Chinese people must have strong confidence. Even if it takes 50 or 60 years, we must speed up the pace and compete for the first place in innovation to complete this task. Duxiangwan, academician of the Chinese Academy of Engineering: The diversity of values is more important to inherit and carry forward the feelings of home and country On the Sixth National Science and technology workers' day, I would like to talk about my understanding of the spirit of scientists: the feelings of home and country and the responsibility of mission are the soul of the spirit of Chinese scientists I feel. In the 1950s and 1960s, under extremely difficult circumstances, a group of scientific and technological workers, workers and the people's Liberation Army achieved the cause of "two bombs and one satellite". Therefore, we condensed 10 words: "build the cornerstone of national defense and become the backbone of the nation". This backbone is not a person or a few weapons, but a kind of culture and spirit. Among them, the core is the spirit of striving for national rejuvenation. It is this spirit that unites us, becomes the spiritual pillar to overcome various difficulties, and becomes an indestructible spiritual force. In the 21st century with diversified values, this spirit not only needs to be inherited, but also needs to be carried forward. In fact, the young and middle-aged generation, which is becoming the main force in the scientific and technological community, has made innovative achievements and practiced the feelings of a new generation. For example, the meteorological team of Waliguan base, China's atmospheric background reference Observatory, located in Qinghai Province with an altitude of nearly 4000 meters, not only made Chinese contributions to coping with climate change, but also demonstrated the benchmark of scientific spirit with decades of persistence. Today, although we have made great achievements in science and technology, we are still far from the goal of becoming a powerful country through science and technology. To achieve a high level of self-reliance and self-improvement in science and technology, it is necessary to cultivate a number of world-class scientific and technological talents, so that China's scientific and technological level can truly lead the world, achieve the historic goal of becoming a powerful country through science and technology, and make greater contributions to the progress of human civilization. Luyanhui, deputy director of Institute of plant protection, Chinese Academy of Agricultural Sciences: Aggressiveness and motivation come from farmland and cotton farmers I am mainly engaged in cotton pest control research. The older generation of scientists in the team braved difficulties and pursued truth. Since the 1950s, they have been rooted in the rural areas of North China for more than 60 years, and have successively overcome core technologies such as chemical prevention and control of cotton pests and comprehensive management of cotton bollworms, providing important scientific and technological support for ensuring the safety of cotton planting in different periods in China. They explained what is the spirit of scientists, and answered with practice who agricultural research is for. Their earnest teachings have enabled me to establish the scientific spirit of overcoming difficulties and scaling new heights from the beginning of my research career, and have also enabled me to establish the original mission of focusing on major national needs, breaking the bottleneck of Industrial Science and technology, and supporting the sustainable development of agriculture. In the 21st century, with the strategic adjustment of cotton planting layout, Xinjiang has gradually become the main battlefield of China's cotton industry. The vast number of scientific and technological workers should write their papers on the land of the motherland and apply their scientific and technological achievements to the great cause of modernization. I left the superior Beijing Laboratory, led my team and students to the north and south of Tianshan Mountain, successfully broke through the bottleneck of green pest control technology in Xinjiang, and effectively assisted the green and high-quality development of cotton in Xinjiang. Over the past 12 years, I have become familiar with Xinjiang from unfamiliar to familiar. Although I have experienced many difficulties and challenges, when I face the vast farmland and hardworking cotton farmers, I naturally have responsibilities and responsibilities, strong and tenacious, as well as a steady stream of aggressiveness and motivation. Lihongbo, deputy chief engineer of the first Research Institute of China Aerospace Science and Technology Corporation: Set a high standard and be strict with yourself As an aerospace engineer, in the aerospace field, we should explore the vast universe, develop the aerospace industry and build a aerospace power. As a scientific and technological worker, on the scientific research front, we should build a world power in science and technology. Scientific achievements are inseparable from spiritual support. In the aerospace field, we have inherited the spirit of "two bombs and one satellite" and the spirit of manned space flight. Our generation of aerospace youth also grew up under the inspiration of this mission. Scientific and technological innovation has now become the main battlefield of international strategic game. As scientific and technological workers in the new era, we need to shoulder the important task entrusted by the times and strive to achieve high-level scientific and technological self-reliance. This not only needs to practice the spirit of scientists, but also needs us to carefully cultivate and strive to maintain the spirit of scientists. Having the opportunity to shoulder the responsibilities entrusted by the times, I deeply feel that the mission is glorious and the responsibility is great. I will be strict with myself with high standards, carry forward the spirit of scientists, cultivate a good style of study, strive for innovation and self-reliance. Inherit, carry forward and spread the spirit of scientists, and strive to build a strong country with science and technology. (Xinhua News Agency)
