The theoreticalanalysis and numerical experiments show that the multiscale finite element method presented in this paper is very effective to solve above these kinds of problems.
The theoreticalanalysis and numerical results of two typical examples show that this method can decrease the numbers of iterative by30%and reduce the computation time greatly.
