摘　　要：讨论了计算二维静电场的非正交有限差分算法，给出了数值计算公式。通过对一些实例的计算以及与理论解的比较，结果表明非正交有限差分算法具有数值网格与边界吻合的特点，只要较少的离散网格就可以达到较高的精度。A finite difference method in non orthogonal curvilinear coordinate is used for the simulation of two dimensional electrostatic field. The computational formula is derived. Several electrostatic problems are calculated. The results show that numerical meshes fit the complex boundary well and higher accuracy can be got by less numerical discrete cells.
