Abstract: Linear convection-diffusion equation of two-dimensions is discussed.A new kind of characteristic-difference algorithm is for linear convection-diffusion equation of two-dimensions,constructed by combining characteristic method with the finite-difference method and with the help of bilinear interpolation method.And it analyses the convergence of this characteristic-difference algorithm.This algorithm shows that it can eliminate the numerical oscillations more efficiently by the application of this difference format for a category of convection-diffusion equations and can greatly improve the approximation rate of numerical value.
