摘　　要：在计算Possion方程特征值时,高效率更准确是我们追求的目标。本文在二维情况下用Qr1ot非协调元二网格法求得了Qr1ot元的特征值,并且与非二网格下得到的结果进行了比较,用数值例子说明了此方法具有高效性。The efficiency and velocity are the objectives when the eigenvalue of Poisson equation is calculated. In this paper, the eigenvalue of Q1^rot element is obtained with the method of two-grid method in two dimention and eigenvalue is compared with the result of non-two-grld method. The efficiency and velocity are displayed with the example of numerical value in this paper.
