摘　　要：讨论了用分层求解的思想来快速构造二维数值网格。把以往文献中针对于外场区域的解抛物型方程的方法推广到封闭的二维区域，并把分层求解的思想应用于更为复杂的用椭圆型方程构造网格的数值求解中，给出了一些闭域的网格构造图。Fast generating two dimensional numerical grids line by line is discussed. Grid generation method which uses parabolic partial differential equations for external region of bodies in References is extended to enclosed region. The idea is also applied to solve more complex elleptic partial differential equations for grid generation. Some generated grids by the method are presented.
