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. bat fidget spinnerpersonalised wristbands24hourwristbandshow to make rubber braceletscustom rubber wristbandsprinted wristbands
They'll cover the National Congress from fresh angles A total of 1,818 overseas journalists, including correspondents from the Hong Kong and Macao special administrative regions and Taiwan, have registered to cover the upcoming 19th National Congress of the Communist Party of China. That is 6.7 percent more than those who covered the 18th CPC National Congress five years ago, Hu Xiaohan, director of the congress's press center, said at a media reception attended by more than 500 overseas journalists on Monday. Hu said the foreign journalists come from 134 countries, about 20 percent more than in 2012. For the first time, the press center opened an official WeChat account, which provides online information for journalists about the agendas, notices and other items of interest. The center first developed a registration system for media applications, accepting those from foreign media and from Hong Kong, Macao and Taiwan. Everybody is waiting for what the congress is to come out with, said Kajubi Mukajanga, executive secretary of the Media Council of Tanzania. He attended a forum on the Belt and Road Initiative with media organizations from several countries earlier in the day. He said he will focus on China's stability, economic growth and poverty alleviation efforts at the congress. Many journalists are looking at China's endeavors in areas like poverty relief. Mukajanga said China's poverty alleviation is a truly alternative way of doing things. Bipul Pokhrel, vice-president of the Federation of Nepali Journalists, said media can work with the government to enhance poverty alleviation. Media can support the government. It's possible to create change for good. That's a great message from China to us, he said. Aly Diouf, a journalist from Senegal, said he is impressed with anti-desertification steps being taken in the Inner Mongolia autonomous region. At every step, there are efforts - the national, provincial, municipal and district levels. Things are being done to enable people to leave poverty and live with dignity, Diouf said. The congress allows us, as African journalists, to experience China in our own way. We Africans see there are positive things here in the Chinese (system).
