利用经典的超圆方法和最低阶Raviart-Thomas H（div）元得到了二维Poisson方程P1有限元解的后验误差估计.为了比较，还讨论了其他几种估计方法。我们给出了一些理论和数值结果，看看该方法的有效性。
We utilize the classical hypercircle method and the lowest-order Raviart–Thomas H(div) element to obtain a posteriori error estimates of the P1finite element solutions for 2D Poisson's equation. A few other estimation methods are also discussed for comparison. We give some theoretical and numerical results to see the effectiveness of the methods.
