摘　　要：本文将推进迭代法推广到不可压缩流的N-S方程求解。给出了曲线坐标下的一般表达式,将推进迭代法应用于方框流及圆柱绕流,得到的结果表明该方法具有较快的收敛速度和能够得到满意的结果。The marching-iterative method(MIM) is extended to solve the N-S equation of the steady incompressble viscous flow. The general formula in arbitrary curved coordination are also given.The MIM sis used to calculate the flows in a cavity and around a cylinder.The reults show that the speed of convergency of this method is rapid and the satisfactory results can be obtained from this method.
