摘　　要：作者用两点边值问题的方法,数值求解了平面波在径向任意连续分层不均匀等离子体球上的散射问题,平面波用位函数表示,而位函数被分解成球面波,将球面波在分层介质上的散射简化成一个两点边值问题,根据给出的边界条件和统治方程,得到了散射系数.The scattering of plane wave from continuously layered plasma sphere is studied by two-point boundary value problem method. The plane wave is expressed in potentials. The potentials are decomposed into spherical waves. The scattering of spherical waves from a continuously layered plasma sphere is reduced to a two-point boundary value problem. The boundary conditions and governing equations are given. The scattering coefficients are given.
