| 摘 要： | 二维静态场对一些特殊对称的边界才能求它的解析解，而许多实际问题由于边界条件复杂需要借助数值法求场域的电位分布。文章以方形同轴线静态场域边值问题为例，论述了有限差分法和有限单元法数值计算的过程中，用MATLAB实现是一种行之有效的方法。

| Abstract: | There are analytic solutions for two-dimension static fields of some special and symmetry distributes. But because of the boundary term complicacy of many actual problems, electric potential problem of static fields between coaxial quadratic form as an example and discusses that MATLAB realization on the electric potential numerical calculation is effective in the process of numerical calculation of finite difference method and finite-element method. |
