摘要针对一类带间断系数的椭圆边值问题，在非结构四边形剖分下，讨论了两种二次拉格朗日有限元方程的代数多重网格法，通过利用双线性元和二次元基函数之间的表示关系，给出了一种新的网格粗化算法和构造提升算子的代数途径。 - Through extrapolation , the order is poromted from 2 to 4 . for rannacher - turek element , its single root also gives lower - bound approximation . however , it can reach fourth order and further extrapolation leads to sixth order , while its repeted root has only second order precision and extrapolation leads to fourth order precision
实验结果表明拓广rannacher - turek元确实给出特征值的下逼近，并且要优于线性元，外推可以使2阶精度提高到4阶，而rannacher - turek元对单根同样给出下逼近，但近似解本身便可达到4阶高精度，外推可以获得更高阶( 6阶)精度，重根却给出上逼近，只具有2阶精度，但可以通过外推达到4阶精度。
