Abstract: The superconvergence properties of R-T elements solution of parabolic equation were proved by integral identical equation. Through interpolation post processing for R-T elements, the bulk superconvergence was obtained，and the posterior error estimates were derived.

Key words: Parabolic equation, R-T elements, Superconvergence  Corresponding

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。

关键词: 抛物方程, R－T元, 超收敛
