【Abstract】 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.更多还原
