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 ,并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 ,揭示了文中所得到的折射规律较之斯涅尔定律更具有普遍性 。The extraordinary ray neither obeys the refractive law, nor has certain index of refraction in anisotropic medium. By means of the hypothesis that the ordinary and the extraordinary rays have different wavelet surfaces propagating in uniaxial crystal, and applying the Huygens'principle, general operational formulas for the refractive direction of the extraordinary ray in uniaxial crystal with arbitrarily oriented optical axis are deduced. And the analytical expressions are given for determining plane of refraction and refraction angles of the extraordinary ray. Finally some special situations are discussed in detail. The refraction regularity obtained is more universality than Snell law, thus the theoretical basis is provided for applying for all kinds of optics cells of uniaxial crystal.
