摘要：
A new discrete approximation to the convection term of the covection-diffusion equation vas constructed in Saul' yev type difference scheme, then the alternating segment Crank-Nicolson ( ASC-N) method for solving the convection-diffusion equation with variable coefficient vas developed. The ASC-N method is unconditionally stable. Numerical experiment shows that this method has the obvious property of parallelism and accuracy. The method can be used directly on parallel computers.
