【摘要】现有的文献资料中根据菲涅耳公式可方便的解释在垂直（掠）入射时反射光与入射光电矢量之间的夹角，即半波损失现象，但在斜入射的情况下反射光相对于入射光其电矢量之间夹角并无定量计算表达式，本文将应用菲涅耳公式给出在任意入射角时反射光相对于入射光其电矢量间的夹角表达式。

【Abstract】In the existing references， the angle between the reflective photoelectric vector and the incident light vector in vertical incidence， namely the phenomenon of half？鄄wave loss could conveniently be interpreted by Fresnel formulae. However， there is not yet quantitative formulae on the angle which is reflected light relative to incident light for oblique incidence. In this article， the formulae of this angle would be given in the case of arbitrary incidence angle by using Fresnel formulae.
