二次三角形元逐点意义下渐近准确后验误差估计

ASYMPTOTICALLY EXACT A-POSTERIORI ERROR ESTIMATORS FOR THE QUADRATIC TRIANGULAR ELEMENT IN SENSE OF POINT TO POINT

采用两种不同方法,得到了二次三角形元逐点意义下渐近准确后验误差估计,后验估计量十分简洁。

Using different methods, two kind of a-post-eriori errorestimators for the quadratic triangular element are obtained. In the senseof point to point, the formulas for the error indicators and error estima-tors are very concise and available.
