China needs to prioritize the tackling of solid waste pollution and strengthen supervision over implementation of related law, the country's top legislature said on Tuesday. The Standing Committee of the National People's Congress conducted inspections this year on the enforcement of the law on solid waste pollution for the first time since 2005, when the revised law took effect. The inspections were finished by the end of August. Inspection teams headed by top national legislators including Zhang Dejiang, chairman of the NPC Standing Committee, visited 10 areas including Tianjin, Shanxi and Jiangsu provinces. Legislators and leaders of the ministries involved discussed the results at a meeting on Tuesday. Zhang acknowledged achievements in preventing and tackling solid waste nationwide in recent years. The teams also found problems that cause environmental and health risks, he said. Problems arise from the large quantity of solid waste, from industrial and agricultural sources, inspections showed. "Solid waste controls should be given priority, along with other pollution reduction efforts," Zhang said, because it is closely linked with air, water and soil pollution. The national legislative body will urge governments to enforce the law, he said, since the inspections' results suggest that governments need to improve their procedures to make the prevention efforts work efficiently and scientifically. Shanxi, one of the inspected provinces, has strengthened controls in reducing solid waste by building more plants to process industrial waste, helping the province, China's coal heartland, improve its environmental quality. "In 2016, 66.1 percent of the solid waste from industrial production, like fly ash and coal refuse, has been processed, for an increase of 44.1 percentage points over the level in 2005, when the revised law took effect," said He Tiancai, vice-governor of Shanxi, in a briefing about the control efforts a week ago. Over 123 million metric tons of solid waste was processed last year in multiple ways, said Zhang Zhanxiang, deputy director of the Shanxi Provincial Economic and Information Committee. For example, fly ash, mainly discharged from coal-fired power plants, has been used to make construction materials like autoclaved bricks and cement, Zhang Zhanxiang said. He added that cement production could consume 9 to 11 million tons annually. Shanxi plans to increase the processing rate for solid waste to 70 percent by the end of 2020 in order to tackle the pollution from solid waste and protect human health, He, the vice-governor, said. cool wristbandswristbands onlinebat fidget spinnercheap rubber wristbandsfestival wristbands ukrubber arm bandsballer bands
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.
