摘　　要：用求极限的方法获得了δ束在劳厄情况下入射平行平面板晶体的边界条件,从而求得了Darwin方程的二维解析解,并指出这个解不仅限于平板晶体而是在一个更宽松的条件下成立.对Werner于1965年得出的关于这个问题的结果提出不同看法.The boundary condition of δ-function incident beam in Laue case can be obtained by employing the method of limit. A new analytical solution for Darwin equation in planeparallel crystal has been obtained with this boundary condition, which is different from Werner's. Our result is also valid in more general case.
