摘要
对两单轴晶体交界面上光的折射，根据光的电矢量满足的边界条件，得到了波法线满足的折射公式，同时，根据度规光学中光线径迹的零测地线方程导出的Fermat原理，推得了光线遵从的折射定律。文章所得解析公式完全可以确定折射光的波法线和光线的方向。
The refraction of light is discussed on boundary surface between two uniaxial crystals. The refraction foumulas of the wave normal are obtained on the basis of the boundary condition of the electromagnetic wave. And the refraction formulas of the light ray are derived by the Fermat's principle which is suited for the uniaxial crystal. The refraction directions both the wave normal and the light ray can be calculated by the formulas above.
