摘　　要：提出了一种新的Ｎ－Ｓ方程的离散格式，本格式具有良好的自动迎风特性，满足正系数规则，适用于任意网格，算法简单。A new discrete scheme for N -S equations is presented in this paper. The scheme withgood self - orientating wind character satisfies the positive coefficient rule and is suited to arbitrary grids. Moreover, the corresponding algorithm is simple.
