| 摘 要： | 无网格法是近期发展起来的一种数值计算方法．其的形函数构造有多种方法。为此，着重介绍了较常用的两种方法：移动最小二乘法(MLS)和光滑粒子法(SPH)，并对这两种不同的方法进行了阐述。对比了这两种插值函数的异同．最后又用数值算例对其计算精度进行了比较。

| Abstract: | A meshless method is a numerical method which was developed recent years. There are many different methods in constructing the shape function. This article focuses in two methods widely used, namely MLS(moving least-squares) method and SPH(smoothed particle hydrodynamics). The article lists the different methods and contrasts the difference between the two interpolate function. In the end numerical examples are used to compare the accuracy of the proposed methods. [ |
