The initial or frozen-in double refraction is replaced by an equivalent or virtual state of stress.
初双折射或被冻结的双折射,可用一个等效或有效应力状态来代替。

This is a diffuse phenomena, its specular equivalent would be something like transparency or refraction.
这是一个漫的现象,它会像镜面等于或折射透明度。

The refraction effect complex operation can be greatly simplified by using equivalent earths radius; therefore it is widely available in the actual project.
