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. medical bracelets ukbracelet maker onlineslap wristbandsbatman wristbandhow to make rubber braceletscustom rubber band bracelets

[Photo/VCG] The situation in the South China Sea has stabilized and will remain stable as long as countries outside the region refrain from making troubles, State Councilor and Foreign Minister Wang Yi said on Tuesday. China and member countries of the Association of Southeast Asian Nations will speed up consultation on the Code of Conduct in the South China Sea on the basis of comprehensive and effective implementation of the Declaration on the Conduct of Parties in the South China Sea, Wang said during a meeting with ASEAN Secretary-General Lim Jock Hoi. China believes that a new round of senior officials meetings, which will be held in China at the end of this month, will achieve new progress, Wang said. He emphasized that as long as outside forces stop making waves, consultations on the COC will push forward smoothly. The state councilor noted that China and ASEAN will work out the China-ASEAN Strategic Partnership Vision 2030 to make medium-and long-term plan for future cooperation. That 2018 is China-ASEAN Innovation Year will provide new driving forces for bilateral relations and their respective development, Wang said. China and ASEAN will also strengthen the synergy between the Belt and Road Initiative and ASEAN's development plan like the Master Plan on ASEAN Connectivity 2025 to explore new areas for bilateral cooperation, he added. This year marks the 15th anniversary of the establishment of the China-ASEAN strategic partnership. In 2003, China became the first country to join the Treaty of Amity and Cooperation in Southeast Asia and establish a strategic partnership with ASEAN. It was also the first country, in 2002, to sign a free trade agreement with ASEAN and has led other major countries to pay more attention to and accelerate their relations with ASEAN, according to Wang. The ASEAN secretary-general said that China is the most dynamic strategic partner of ASEAN, and the ASEAN Secretariat will play a positive role in deepening the cooperation between both sides in areas like politics, economy and people-to-people exchanges. According to the Commerce Ministry, bilateral trade volume between China and ASEAN reached $514.8 billion last year. China is ASEAN's largest trade partner and ASEAN is China's third-largest trade partner.
