中文摘要：

在分析边界元法中多种角点处理方法的基础上,提出了一种新的方法—单角点法.该方法在继承双角点与二重节点法优点的基础上,不仅提高了解的精度且有效解决了边界变形的问题.

英文摘要：

Based on analyses of several available methods to solve corner problem in the boundary element method,we propose a new algorithm,single corner method.The new algorithm inherits merits of the double corner method and dual-node method,improves the solution precision,and overcomes the boundary deform problem.
