摘　　要：应用传递矩阵方法，从光强反射率和透射率得到苯胺等离子体聚合膜的复数折射率和复数介电函数。在０．５μｍ～２．５μｍ波长范围内，膜的折射率ｎｆ不随波长明显变化，其最佳值为１．６５±０．０５。由复数介电函数的虚部得到膜的光学能隙为１．８ｅｖ，与从吸收谱得到的结果（Ｅ０＝１．７６ｅｖ）基本一致。The complex refractive index and complex dielectric function for the plasma polymerized film starting from aniline have been evaluated from the reflectance and transmittance sprectra using the method of tansfer matrix.In the 0.5μm～2.5μ wavelength range,the optimal value of refractive index for the sample is 1.65±0.05which does not change obviously with λ.The optical gap E0 was detenmied to be 1.8eV form the plot of the quntity versus photon energy hω,This result essentially coincedes with 1. 76eV obtained form the absorption spectrum of the sample.
