ray of refraction的意思|示意

So to the important reflection and refraction results, we must choose a right chain of ray paths.

于是乎，对于拥有折射反射的物体，我们必须要考虑正确的光路。

The radio wave propagation velocity is slowed and the ray producing bend but to the asymmetry of the atmospheric medium, the refraction error is produced.

由于空中大气介质的不均匀性使得电波传播速度减慢射线产生弯曲，从而产生折射误差。

The index of refraction for the extraordinary ray is therefore a function of direction.

折射光线的折射率因此在各个方向不同。
