In this article, method of determination of micro quantity of Mn with GFAAS and Pd have been researched, results of different additional methods of Pd were compared the combining energy of Pd in three heating steps were determined by X-ray Photoelectron Spectroscopy. The point was given that as a catalyst reduced Pd changed courses of Mn atomization, and(More)
Polyvinyl alcohol (PVA), polyethylene (PE) and ethylene-vinyl acetate copolymer (EVA) film was prepared. The optic capability, infrared transmittance and heat preservation capability of the films were studied respectively. The result indicated that the haze degree of the PVA film decreased about 15% and 12% than PE film and EVA film; PVA film transmittance(More)
