ZDK-03 model [Photo/VCG] Designer says few nations are capable of designing, building such aircraft China is a major arms exporter, but its image in the international weapons market has long been linked to old, second-tier products sold at relatively low prices. Domestic defense technology companies have been sparing no effort over the past several years to improve their reputation by promoting modern, advanced products featuring the latest technology. One recent effort is an airborne early-warning and control aircraft described by its designer as world-class and best of its kind. Hu Mingchun, head of the Nanjing Research Institute of Electronics Technology in Jiangsu province, said there are only a handful of nations including China, the United States and Israel that can design, build and export such cutting-edge hardware as early-warning planes. And he said the KLC-7 Silk Road Eye developed by his institute is a generation ahead of its rivals in the global market. According to Hu, the KLC-7 integrates a mechanical scanning system with active electronically scanned arrays - two popular radar detection methods - and features the latest digital technology and processing capacity, which is much more robust than previous models. With state-of-the-art electronics, the system boasts better anti-jamming functions, a longer detection range and stronger target-tracking ability and optimized algorithms, he said. It was designed based on our rich experience and expertise, Hu said. All of its core technologies and components were developed on our own. The product represents the latest technologies and is very competitive in the international market. Several nations have expressed strong interest in the KLC-7 and want to open talks with the institute, he said. For our users, the KLC-7 Silk Road Eye is the best solution to their needs because it fits perfectly in sophisticated and rapidly changing combat situations and can detect and track targets from afar, Hu said. The farther you can see in combat, the higher the chance that you will win. Therefore, anyone who uses the Silk Road Eye will be able to extensively magnify the situational awareness and operational capabilities of military forces. The electronics institute in Nanjing, which is part of State-owned defense giant China Electronics Technology Group Corp, is the country's top developer of military surveillance radar. Its products have been sold to more than 20 nations in Africa and Asia, it said. Reports have said it designed and manufactured the radars mounted on ZDK-03 early-warning aircraft that China exported to Pakistan. In a picture released by China Electronics Technology Group Corp, the Silk Road Eye appears similar to the ZDK-03, which means it is also mounted on the Y-9 turboprop transport plane built by Aviation Industry Corp of China. bracelet montre siliconecheap custom silicone wristbands free shippingembossed wristbandrubber bracelets cheapdual layer wristbands
Other air pollutants are declining in Beijing-Tianjin-Hebei regionThe concentration of hazardous ozone in the Beijing-Tianjin-Hebei region and surrounding areas has been increasing, even though other major air pollutants have been declining, according to a report published on Tuesday.Ozone is the only one of the six major air pollutants - including nitrogen dioxide, sulfur dioxide and PM 2.5 - that is rising, according to the air quality evaluation report published by Peking University's Guanghua School of Management and the Center for Statistical Science.In addition to Hengshui, Hebei province, and Taiyuan, Shanxi province, the average ozone concentration from noon to 8 pm last year in all the other cities had increased since 2013, the report said."There were sharp increases in some cities," it said.The data covered 33 cities.Of those, Dezhou, Shandong province, saw the highest eight-hour ozone concentration in 2017, with 115.6 micrograms per cubic meter, up by almost 38 percent from 2013, according to the report.Data used in the report was gathered from 172 national air quality monitoring stations.Excessive concentrations of ozone can cause respiratory tract irritation, damage the body's immune system and affect lung function.The ozone density in Beijing's downtown area is comparatively lower than in the capital's rural areas, as the gas may react with vehicle exhaust, according to the report."Special attention should be paid to protection from ozone when people visit the rural tourist resorts in the capital," said Chen Songqi, a professor of statistics at Peking University and one of the main authors of the report.The government should also set a target for ozone concentration, as it does for the concentration of PM 2.5, to avoid the simultaneous occurrence of particulate matter pollution and health-harming gas pollution, he said.Generally, there was no obvious decrease in the concentration of nitrogen dioxide in the 33 cities. "Only 11 cities saw the concentration of nitrogen dioxide decrease by more than 10 percent from 2013," the report said.Ground-level ozone can be created when nitrogen oxides, which come mostly from motor vehicles, interact with sunlight. So nitrogen oxide is a major contributor to ozone pollution.Chen, the professor, said the control of motor vehicle emissions "should be one of the focuses in future air pollution control work".
