In order to enhance the filtering efficiency, the inlet and outlet structure of this new style of air filter were improved and the experimental research was carried out. The results showed that the filtering efficiency of the filter exceeded the lowest limit, this new style air filter can be practically developed further.展开更多

Coal used in building materials and the electric, steel and chemical industries accounted for 85 percent of overall coal consumption during the first nine months, data released by the National Energy Administration （NEA） showed. While petroleum consumption remained steady,展开更多
