| 摘 要： | 利用Ｌａｐｌａｃｅ方程的基本解，将变系数非齐次Ｈｅｌｍｈｏｌｔｚ偏微分方程的边值问题化为积分方程问题。再用边界无法进行离散，并对区域结点及边界结点的方程耦合求解。文末算例表明本文方法能够达到较高精度。

| Abstract: | Making use of the fundamental solution of Laplace equation, we change the nonhomogeneous Helmholtz equation with veriable coeffients into integral equation. Furthermore, the solution of couped with domain and boundary points is obtained by separated of BEM. An example is given which shows that the suggested method is feasible. |
