• #### 摘要

对半无穷厚晶体用推迟Green函数G(r),解出X射线在反射情形下的场值Dh,对有限厚晶体,用G(r)和超前Green函数G(a)能类似地求解,将这些结果与其它作者用Rie-mann函数或Fourier积分得到的结果作了比较,吻合是令人满意的。

#### Abstract

For a semi-infinite crystal,the expression for wave field of X-ray reflection,Dh is de-rived by the retarded Green function G(r). For a crystal with finite thickness it can be solred using G(r) and advanced Green functions Ga as well.These results have been corn.pared with previous results obtained by using Riemann function or Fourier integral andit is found that they are in agreement quite well.
