摘　　要：提出了δ束入射到平面晶体时边界条件的处理方法,进而求得了δ束入射到平行平面板晶体时,布拉格情况的束流强度二维解析解。利用上述结果讨论了有限宽入射束的Fankuchen效应。A method to obtain the boundary condition in the case of δ-function incident beam is introduced. The 2-dimension solution to Darwin equation in plane-parallel crystal in Bragg case is acquired by using the method, and the Fankuchen effect is also investigated.
