摘　　要：本文主要讨论了基于区域分解的双调和方程的混合元近似解的分裂外推。并得到解的多变量展开。In this paper, we dicuss the splitting extrapolation based on domain decomposition for mixed finite element approximation of biharmonic equation occured in large scale scientific and engineering computation in parallel. The multi-variate asymptotic expansions of mixed element on independent mesh parameters are provided for biharmonic equations.
