摘　　要：讨论了浅海中波导的声波散射问题.利用单层位势理论将声波散射的外边值问题化为一个第一类边界积分方程,利用矩量法对积分方程求解,给出了二维空间的数值结果.结果表明其精度比Tikhonov正则化方法稍差些,但计算方法简单,计算机的实现快速.The problem of acoustic wave scattering in shallow oceans for waveguide is discussed. The single-layer potential theory is used to formulate the exterior boundary value problem into a boundary integral equation of the first kind which is solved by moment method. Given the numerical result proved that the accuracy of numerical result is less than Tikhonov regularation method. But the computing is simple and speedy.
