1.APPLICATION OF AIR PHOTO INTERPRETATION IN SOIL AND LAND USE CAPABILITY SURVEY IN UPLANDS OF NORTHERN ENGLAND
3.A semiconductor compound system (ZnO-CuO-H2O2-air) used for photo-catalytic degradation of the six dyes was studied. The system presents good effects on deco-louring and COD-removing.
4.In 2002, we develop Photo-catalyst &electronic Ionizer Air Purifier.
6.As the globally strategic partner of the Air Products and Chemicals, Inc. (hereinafter referred to as “AP”), it will provide the choice gases and technical solutions to such photo-electron fields as optical fiber, flat-panel display and laser gas as well as such industries as metal heat-treatment, glass and food processing.
