摘　　要：基于光线遵从的Fermat原理,从几何学的角度讨论和分析了在单轴晶体中入射的e光线在界面上的双反射,得到了确定光线反射方向的一般公式,并对几种特殊情况进行了讨论.指出了上述结果与由电磁波的边界条件计算所得结果是一致的.On the basis of the Fermat principle of the anisotropic medium, the reflection of the incident e-ray is discussed and analyzed on the internal boundary surface of the uniaxial crystal. The reflection formulas of both o-ray and e-ray reflected is derived in any direction of optical axis of the uniaxial crystal, and some special cases are discussed. It is also pointed out that the result is the same as those calculated on basis on the boundary condition of the electromagnetic wave.
