反射波振幅与入射波振幅的比率称作反射率或反射系数。
The ratio of the amplitudes of the reflected and incident waves is termed the reflectivity or reflection coefficient.
我们发现反射系数在波矢时，反射率与波矢在时呈线性关系。
We find that reflection probabilities and reflectivity is linear to when wave vector.
反射波振幅与入射波振幅的比率称作反射率或反射系数。
Reflectance: The relative amount of reflected light of a surface. May be expressed in percentage.
