应用XPS、循环伏安曲线和极化曲线测定等手段对载波钝化膜的组成及各成分在膜层中的纵向分布进行了测试分析，据此讨论了膜层及膜层中组份的性质和作用，提出了载波钝化膜的生长机理．
The composition of the passivation film and the longitudinal distribution of the components in the film were tested by means of XPS, cyclic voltammetry and polarization curves. The properties of the components in the film and the film were discussed And the role of the carrier passivation film growth mechanism.
