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. 1 inch wide rubber bandsfestival wristbands for saleprintable wristbandsblack rubber wristbands
A delegation made up of around 150 young people from a variety of sectors in Hong Kong visits the Palace Museum in Beijing to learn about Chinese history on Friday, the last day of their five-day visit to the mainland. [Photo/China Daily] Vice-Premier Han Zheng encouraged young people from Hong Kong on Friday to enhance their knowledge of the nation and pursue their careers considering both the special administrative region and the nation's development. Han, a member of the country's top political authority, the Standing Committee of the Political Bureau of the 19th Central Committee of the Communist Party of China, also called on the young people to contribute to the long-term prosperity and stability of Hong Kong and realize the Chinese dream of the great rejuvenation of the Chinese nation. Han made the remarks when meeting with a Hong Kong youth delegation in Beijing. The delegation of 150 included a cross section of the SAR's young people. Han said President Xi Jinping cares about youth development and has great expectations for Hong Kong's youth. A nation will prosper only when its young people thrive, Han said. Han also expressed his hope that the city's young people will be patriotic, persistent in realizing their dreams and committed to serving the SAR and the country. The delegation, of youth aged 18-35, was on a trip to Shenzhen, Wuhan and Beijing by high-speed rail this week with a special focus on the nation's booming innovation and technology industries. Delegation head Kenneth Fok Kai-kong called meeting Han of great significance as the young people learned that the country's development has set the stage for them to realize their dreams in a historic opportunity. Fok, who is a Hong Kong member of the National Committee of the Chinese People's Political Consultative Conference, the country's top political advisory body, added that it would make Hong Kong's youth-related work more inspiring. Andy Tsang Hin-lam, a freshman history major at the Chinese University of Hong Kong, said Han's remarks showed that the future of Hong Kong youth is not just limited to Hong Kong. He called on his peers in the special administrative region to broaden their horizons and take part in national development. Tang Chui-lee, a sophomore studying movie and TV production at Hong Kong Design Institute, said she learned that the country has provided great policies and resources, and young people should seize opportunities in a timely and proactive way.
