摘　　要：在单轴晶体光轴任意取向的情形下应用惠更斯原理导出了非寻常光折射方向的普遍计算公式,给出了确定非寻常光线折射面和折射角的具体解,结合几种熟知的特殊情形进行了简要讨论,揭示了所得到的非寻常光折射方向的普遍计算公式较之斯涅尔定律更具有普遍性,从而为光学系统中各类单轴晶体光学元件的应用提供了一个理论依据。With the case of any orientation of optical axis in uniaxial crystal, universal calculation formulae for extraordinary light refractive direction is derived and the concrete solution for the refractive plane and refractive angle are determined by means of Huygen's principle. A simple discussion is carried out by combining several special familiar cases and they reveal that the obtained universal calculation formulae for extraordinary light refractive direction has better universality than Snell law, thus provides a theoretical basis for applications of various kind of uniaxial crystal optical element to optical system.
