根据慢正电子束流在WO〓薄膜变色过程中测量结果，从电子结构角度提出了新的变色机理，成功的解释了不同结构WO〓薄膜变色性能的优劣，同时也证实了膜表面的吸附作用。

Study the activity of inducible nitric oxide synthase in the liver of rabbits infected with Eimeria stiedai, the concentration of nitric oxide in the serum、the coccidian oosysts per gram feces ,Score the pathologies according to anatomic structures of rabiits'livers and micoscopic pathological changes. So as to study the effect of exogenous NO and NOS of the rabbits infected with E.stiedai. The results showed that when the rabbits were infected with E.stiedai, the activity of iNOS in the liver and the concentration of NO in the serum gradually increased and they both reached the peak after 12 days in the control group , GTN and GSNO groups.
