为分析非常偏振光在晶体表面的能量损耗，给出一种求解反射率和透射率的方法，即根据电磁场的边值关系以及晶体的双折射和双反射现象，求解晶体光轴在入射面内时，非常偏振光从各向同性介质入射到晶体和从晶体出射到各向同性介质两种情况的反射率和透射率的方法，并给出反射率和透射率的解析解，同时得到对于晶体光轴在入射面内的情况，光轴的取向对非常偏振光反射率的大小几乎没有影响，但对产生全反射的临界角θc影响较大的结论。

Because there is a large variety of the international factoring, such as double factor system and single factor system, non-recourse factoring and recourse factoring and so on.And different varieties can mutually combine, so the customer operates the different ways when choosing different factoring,naturally the factor may face different risks.This involves wide and complex contents.Owing to the article space, this text only analyzed the risk that the factor face taking the double and nonrecourse factoring for example, needing to have more research still.

由于国际保理种类很多，比如无追索权保理，有追索权保理，单保理、双保理等等，而且不同的保理方式又可以相互组合，因此客户在选择不同的种类的时候其运作方式是不一样的，那么保理商所面临的风险也是有所差别的，这涉及面很广而且内容也十分庞杂，鉴于文章篇幅，本文只对无追索权的双保理模式中保理商所面临的风险进行了粗浅的分析，尚待更加细致的研究。
