摘　　要：采用物理坐标在变换平面求解拉普拉斯方程的方法生成正交坐标系 ,提出了双连通域的边界条件的处理及其数值计算过程 .用梅子洲河段的正交网格生成作为算例 ,其结果表明Through solving the Laplace equations about physics co ordinate to transform plane,a numerical method of determining the grid points had been successfully used to generate the orthogonal co ordinate system.the disposal means of the boundary condition & the numerical method for the two connexity area had been advanced .The means obtained the preferable effect for generation of the orthogonal co ordinate system in the Meizizhou reach.
