关于光在两种透明介质界面处反射、折射的能量守恒的研讨

THE DELIBERATION ABOUT CONSERVATION OF ENERGY WHEN LIGHTS REFLEX OR REFRACTE THROUGH TRANPARENT MATTERS

本文以电磁场理论为基础推导出光在两种透明介质界面处反射、折射时能量守恒定律用相对光强表示的正确表达式；指出一些措误的结论及其产生的原因；导出反射率与透射率用相对光强表示的关系式，纠正了错误观念，并讨论了光由光密介质射入光疏介质时出现折射光的相对光强大于入射光的相对光强。讨论了这个结果并不违背能量守恒定律．

The areticle basised the theory of electromagnetic field infers the formula of conservation of enery when lights reflex or refrate through transparent matters.It's showed by relative light intensity,and points out the crrors and the causes of them.Infers the formula of reflectance and the index of refraction wrote by relative light intensity.Moreover the article corrects vrong concept,discusses that the relative light intensity of refraction when lights through optically thinner medium to optically denser medium is bigger than that of reflex,and this result doesn't go against the canservation of energy.
