摘　　要：针对定常对流扩散模型方程 ,在分析已有的几种计算格式的基础上 ,提出一种新的求精算法 ,从而使得收敛速度和计算结果精度得到了显著的提高 .In this paper, several calculating schemes and their accuracy for solving the steady convection diffusion equation are analyzed and contrasted. The problems in these calculating schemes and the treating method are pointed out. A new kind of calculating method is brought up. Some calculating examples prove that the new calculating method remarkably raises the convergent speed and the accuracy of calculation.

关 键 词：计算模式 精度 定常对流扩散方程 算法
