本文分析了边界层效应产生的原因 ,提出了运用插值函数解决边界层效应的方法 ,给出插值节点选取的方法 ,其特点是插值节点的选取与边界单元的划分密切相关。数值算例表明 ,这些方法是完全正确的 ,且既简单又有很高的精度。

The paper introduces the reason of the boundary layer effect in BEM and proposes the means to solve the boundary layer effect by using intergolation method. The way for selecting the intergolation point is given,its character lies in selecting the intergolation point in terms of boundary discretizaton. The numerical examples show that the method is correct,and not only is simple but also has higher accuracy.
