HQ-9 air-defense missile is one of the air-defense missiles developed by researchers at China Aerospace Science and Industry Corp's Second Academy. FAN SONG/FOR CHINA DAILY China has become a world leader in air-defense technologies thanks to the hard work and dedication of researchers at China Aerospace Science and Industry Corp's Second Academy, the country's major developer of air-defense weapons systems. Researchers from the academy's Zhang Yiqun Laboratory have been playing a vital role in the development of China's new air-defense missile system by designing its control systems - the brain of any missile. Compared with previous generations of air-defense missiles, the new-generation missile system will have a wider range of targets and be much more technologically sophisticated, taking China into the ranks of just a handful of nations capable of designing and producing such a system. The cutting-edge missile's control systems need to be extremely efficient and accurate, said Wang Mengyi, deputy head of the Second Academy's General Design Department and former leader of the laboratory. Metaphorically put, the mission of these control systems is to guide a needle to fly 1,000 kilometers to pierce the eye of another needle, he said. For researchers from Zhang Yiqun Laboratory, their mission is to turn this seemingly impossible task into reality. Wang said control systems are mainly tasked with working out a missile's best trajectory and making sure it can hit its target. The successful development of China's new air-defense missile system would be unachievable if researchers at the laboratory had failed to design world-class control systems, he said, noting that they adopted new design methods that have reduced design time tremendously and improved missile performance. Wang Xiaodong, a laboratory researcher, said members of the laboratory spent numerous days and nights improving the accuracy of control systems and optimizing the algorithms that are central to them. For example, we worked 10 consecutive days and slept little each day to detect and resolve one extremely rare abnormality because all of us are aware that our nation's air-defense networks can only be reliable if we are meticulous and responsible toward our work, he said. The laboratory, named after Zhang Yiqun, a top researcher at the academy and former head of the laboratory, has been granted 11 National Science and Technology Advancement Awards and 28 National Defense Science and Technology Progress Awards due to its extensive contribution to China's air-defense networks. It has also registered more than 130 defense technology patents. In the laboratory, members of the Communist Party of China play a vanguard, exemplary role, leaders of the laboratory said. They always take the lead in innovating, carry out their assignments carefully, with scrupulous attention to detail, and also display an inspirational level of diligence and devotion toward their work. fabric wristbands ukpersonalized silicone braceletsbatman wristbandsilicone fidget spinner
China and India, both large economies developing at a fast pace, should enhance their cooperation and dialogue to promote their ties and better contribute to the global economy, scholars from both countries said at a weekend forum. Chinese and Indian academicians gathered at the Second China-India Think Tank Forum on Saturday and Sunday in Beijing to discuss "strategic cooperation and developmental partnership". The forum, sponsored by the Chinese Academy of Social Sciences and India's Ministry of External Affairs, covered issues of strategic communication, trade and investment, people-to-people exchanges and science and technology. At its opening ceremony, CASS President Wang Weiguang said China and India are "two important forces in the world's process of multipolarization" and their think tanks should participate in strengthening their bilateral cooperation. China-India cooperation benefits not only the two countries, but also Asia and the world, Wang said. India's delegation consisted of 17 experts and scholars from 11 Indian think tanks and institutions, said Nalin Surie, delegation head and director general of the Indian Council of World Affairs. The two countries "are expected to play a much greater role in international affairs", said Surie, who is also a former Indian ambassador to China. "We have a variety of reasons to cooperate and collaborate, rather than entering into needless competition or rivalry," he said. The two countries should ensure that differences between them do not become disputes, he said, but are converted into opportunities for greater cooperation. China and India established the forum in 2015, and it was first held in December the following year in New Delhi. The two countries will alternate as host of the annual event. Indian Ambassador to China Vijay Gokhale said, "The genesis of this platform lies in our shared belief in the need for greater and more sustained dialogue among our scholars and academics." The ambassador called for "sustained and in-depth dialogue" at the governmental as well as societal levels in order to sustain ties between the two countries. China and India are the world's two most populous countries and are regarded as important players in the global economy. Hu Shisheng, director of the Institute of South and Southeast Asian and Oceania Studies under the China Institutes of Contemporary International Relations, said on the sidelines of the forum that the two countries should focus on cooperation in development. They "have many similar aspects in their national conditions", and communication on developmental issues will help build a more solid foundation for the bilateral ties, Hu said. [email protected]
