摘要
利用位势理论将阻尼边界条件的声波散射问题转换为一个第二类边界积分方程,在二维情形下给出了Nystrom方法,Garlerkin方法和配置法这三种数值方法并通过对具体的数值例子的分析比较表明Nystrom方法在处理该问题时是最好的。
Potential theory is used to transfer the impedance boundary condition scattering problem into the boundary integral equations of the second kind. Three numerical examples in two dimensions are given, these methods are both accurate and simple to use and Nystrom method is the best one for this problem by comparing and analyzing the numerical results,
