In this paper, we expand eigenvalue of poisson equation using bilinear element, by the formulation of the error expanition, we can conclude that it is a upper bound. and by two numerical example, we computer the approximate eigenvalue of poisson equation in square and l - shape domains, then we analyses the approximate eigenvalue. we also extraplate the error expansion and enhance the accuracy of the eigenvalue form the second order to the forth order
本論文對poisson方程的特徵值採用雙線性元進行展開,得到了誤差展開式,通過誤差展開式,我們能得到特徵值是上界。通過數值算例,計算方形與l形區域上的poisson方程的近似特徵值,並對數據進行分析,驗證了理論的正確性,然後通過對誤差展開式外推,收斂級數可以從二階提高到四階,得到了高精度的解。
