摘要
从晶体的简正模方程出发，求得在双轴晶体中光轴方向，及当光线沿光轴方向行进时所对应的电场矢量和电位移矢量，并通过几何作图，证明所有折射光线在晶体内均在同一锥面上．
From the equations of normal modes of crystals, the direction of the optical axis in biaxial crystals is found and the corresponding vectors of electric field and electric displacement are derived when lights travel in the direction of the optical axis. All refracted lights fall on the surface of the same cone through drawing a geometric diagram are proved.
