The hybrid boundary node method (HBNM) and the dual reciprocity method (DRM) are combined for solving potential problems in this paper.

提出了将杂交边界点法和双重互易法结合求解势问题的一种新的算法。

The concept of extended boundary node was presented. By using finite difference method, the solution of the gained difference equations was given and simulated by computer.

由此提出了扩展边界节点的概念，并使用有限差分法，对所得到的差分方程组进行了计算机求解及模拟。

To ensure the existence of boundary sides and faces, local tetrahedralization method is adopted, needing add no node into the origin surface triangulations.

采用局部剖分的方法来保证边界的完整性，不需要添加新的节点到原始表面三角形中。
