用傅氏积分解出在完整晶体下波动方程的Green函数,通过Green公式求出透射X射线波场Dh,D0的表达式,并在入射波为平面波和球面波时,将得到的Dh,D0值与其它作者的结果作了比较,也讨论了样品厚度与Dh,D0的关系。Green's function of the wave equation for a perfect crystal is obtained by means of Fourier integration. Using Green's formulae, the expression of X-ray transmission wave field, D0 Dh, have been derived. With incident spherical and plane wave, Dh,D0 value are found and compared with previous results of other authors. Relationship between thickness of the sample and D0, Dh is discussed.
