摘要
利用积分恒等式证明了抛物方程R-T元解的超逼近性质,对R-T元通过插值后处理,得到了整体超收敛,并得到了后验误差估计。
Abstract: The superconvergence properties of R--T elements solution of parabolic equation were proved by integral identical equation. Through interpola.tion post processing for R--T elements, the bulk superconvergence was obtained,and the posterior error estimates were derived.
