摘要：
This paper deals with the construction of accurate analytic-numerical approximations of coupled parabolic mixed systems. Using sine Fourier transforms, an exact expression of the exact solution is given. Then, given an admissible error epsilon and a time bounded subdomain Omega, an analytic numerical solution is constructed so that the approximation error is less than E in Omega.
