| 摘 要： | 将自然边界元方法与无网格方法结合起来，提出一种新的数值计算方法——自然边界元的无网格方法，该方法不仅具有自然边界元的降维、计算方便、稳定等优点，还具有无网格方法的只需节点信息、不必划分网格等优点，数值算例给出了令人满意的结果。

| Abstract: | This paper proposed a combination of MLS interpolants with NBEM to retain the meshless attribute of the former and the dimensionality and computation advantage of the latter. It was showed that nodal data on the boundary were needed in the numerical implementation of the method, and the computation was simple and stable. Numerical examples provided satisfactory results. |
