摘　　要：文中给出了二,三维试函数的改进形式、基于子域的残值方程组块稀疏求解算法及权残法通用程序初步。算例表明,用少的配点数达到了优良的精度。In this paper,some improvements for the trial function of two and three dimentional problems, a sparse algorithm based on the subregions for solving the equation system of residual value and a basic frame of general purpose program of weighted residual method are given. The results of numerical examples show that its precision by using less located points is excellent.
