摘　　要：本文根据光传输理论导出介质消光系数、折射率与介质电磁参数、光波频率、电偶极子浓度及迁移率等的关系，分析了光激发与增加气敏介质的氧吸附的规律，结合实验说明气敏薄膜的光学变化机制。Based on the theory of optical transfer,the relationship of extinction coefficient and refractive index of medium with electromagnetic parameter,optical frequency,consistence of electric dipole,mobility,etc.is derived in this paper,and an analysis of the law for optical excitation and increase of oxygenous adherence of gas sensitive medium is given,and an optical change mechanism of sensitive film is explained.
