【Abstract】 In this paper, an optimal difference scheme with high accuracy is suggested for solving one-dimensional convection-diffusion equation numerically. The scheme is used to solve three typical test problems, their numerical solutions are separately compared with those obtained in the previous work, and analytic value. The present scheme gives better results.更多还原
