摘　　要：基于光束在单轴各向异性晶体传播的矢量理论,根据能量交换现象,对寻常光和非寻常光的关系进行了讨论,得出了两个方程,并对其可解性进行了讨论。基于该矢量理论,推导出了一个关于寻常光和非寻常光传播的一个可能的矛盾;注意到矛盾能否成立取决于满足相应波函数条件的方程组是否存在可行性解,即问题转化成了一个数学问题;模拟了高斯光束在单轴各向异性晶体传播的情况,证明了寻常光和非寻常光是独立传播的。According to the vector theory of propagation in uniaxially anisotropyic crystal,the relation between ordinary and extraordinary beams was discussed,and two equations were obtained.The relation between the two beams was determined by whether the equations could be solved.A possible contradiction between ordinary light and extraordinary light transmission was derived,and the problem was converted into a mathematical problem,which depended on the existence of feasible solutions of corresponding equations.Also,the propagation of a Gaussian beam was simulated in uniaxial anisotropic crystal,which proved that ordinary light and extraordinary light transmitted independently.
