| Abstract: | To choose suitable base-functions is a key link on solving he boundary-value problems of two-dimensional elliptic differential equations with variable coefficients by Galerkin method. Using a kind of B-Spline functions with two variables,this paper yields the linear equations corresponding to two-dimensional boundary-value problems,and set up its specific forms,which is advantageous to the practical applications and computer programming. |
