In this study,an arbitrary difference precise integration method for studying convection-diffusion equation with variable coefficients is proposed,which not only retains the superiority of the finite difference method but also the characteristics of the finite element method.Also it is a high accuracy explicit difference scheme with unconditionally stability.Finally,numerical results agree well with those obtained by exact method.
