Weathering steel, i.e. atmospheric corrosion-resistant steel(Corten Steel), is a series of low-alloy steel between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of toughness, plasticity, forming, welding and cutting, abrasion, high temperature and fatigue resistance of high-quality steel. The weathering resistance is 2-8 times of ordinary carbon steel and the coating performance is 1.5-10 times of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used in railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other steel structures exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipme.

"16m infrared hyperspectral satellite atmospheric calibration instrument generation software" started
[ Instrument Network Instrument Development ] Recently, the Optical Remote Sensing Research Center of Anhui Institute of Optics and Mechanics of Hefei Research Institute of Chinese Academy of Sciences received the notice of winning the bid from Guoxin Tendering Group Co., Ltd., successfully winning the bid for the 12th Five-Year Land Observing Satellite Ground System of the National Civil Space Infrastructure. Project data processing system 16 meters infrared hyperspectral optical satellite constellation (2) atmospheric calibration instrument product generation software project. On August 2nd, the research group officially held a project kick-off meeting, and made careful arrangements for the division of tasks and node work arrangements.
The atmospheric calibration instrument load of the 16-meter infrared hyperspectral optical satellite A/B star acquires atmospheric parameters by synchronizing to obtain atmospheric parameters for other satellite loads. The data obtained by the atmospheric calibration instrument needs to be pre-processed and synchronized with the water vapor and aerosol parameters to obtain the calibration parameters of the water vapor and aerosol of the atmospheric calibration instrument, and then perform synchronous atmospheric correction on the main load. To this end, the research team will independently develop a 16-meter infrared hyperspectral optical satellite constellation (2) atmospheric calibration instrument product generation software.
The bidding project began preparations at the end of May 2019. Under the leadership of the research team leader Sun Xiaobing, the members of the project team worked together to complete the task of preparing bid documents with high efficiency and high quality. In the end, with the solid technical strength, perfect closed-loop service and reasonable quotation, it won the recognition of the evaluation experts and the China Resources Satellite Application Center.
