摘　　要：This paper presents a posteriori error estimate of FD-SD method for two-dimensional time-dependent convection-dominated diffusion equation, which can be used to reasonably adjust space mesh. The numerical result shows that this local refinement is accurate and feasible.This paper presents a posteriori error estimate of FD-SD method for two-dimensional time-dependent convection-dominated diffusion equation, which can be used to reasonably adjust space mesh.
