摘　　要：根据光在各向同性吸收介质中传播的分析方法,引入了波法线矢量传播常量,讨论了水平极化光在单轴吸收晶体中的传播规律,得到了波法线折射率、光线折射率、吸收系数等描述吸收晶体性质和光传播性质的物理量的表达式,推导出透明晶体的相应公式.数值计算表明,由该法得到的晶体表面的反射和透射系数与用复折射率表示法得到的结论一致.Based on the analyzing method of light propagation in the isotropic absorption media, wave normal vector propagation constant was introduced. The propagation laws of parallel polarization light in single axis absorption crystal were discussed. The representations of the some physical parameters, which are used to describe the medium properties and light propagation properties, such as wave normal refractive index, light refractive index,absorption coefficient,were derived. The relative formula of transparent crystal can be deduced from these parameters. By numeric calculating, it＇s known that the reflection coefficients and transmission coefficients of parallel polarization light on the crystal surface derived from representation of vector propagation constant are same as those derived from method of complex refractive index. So the method of vector propagation constant to describe the propagation properties of light in absorption crystal is accurate and general.
