摘要
基于透镜形花样的球面三角理论，提出了分析透射点发散Ｘ－Ｒａｙ花样的新理论即虚晶面理论．通过分析发现：目前通用的透镜形花样的球面三角理认仅为虚晶面理论的一个推论。
We have proposed a new theory analysing the pattern of the penetrating point divergence X-ray. i. e. virtual crystal plane theory,which is based on the spherci triangle theory of the pattern of lens model. By making use of analysing the theory, it is faund that the spherci triangle theory of the pattern of lend model that has been widely used is only the inference of the virtual crystal plane theory,it is said that virtual cryatal plane theory includes the spherci triangle theory of the patter of lens model.
