【摘要】現(xiàn)有的文獻(xiàn)資料中根據(jù)菲涅耳公式可方便的解釋在垂直（掠）入射時(shí)反射光與入射光電矢量之間的夾角，即半波損失現(xiàn)象，但在斜入射的情況下反射光相對(duì)于入射光其電矢量之間夾角并無(wú)定量計(jì)算表達(dá)式，本文將應(yīng)用菲涅耳公式給出在任意入射角時(shí)反射光相對(duì)于入射光其電矢量間的夾角表達(dá)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.
