摘要
对第二类Ｆｒｅｄｈｏｌｍ积分方程，以有限元解为基础，建立了一个高精度算法──迭代校正算法．证明了在光滑核条件下，对ｍ次有限元解做一次迭代校正，可使精度从Ｏ（ｈｍ＋１）提高到Ｏ（ｈ３ｍ＋３）．
In this paper the iterative corrections──a high accuracy algorithm based on the finite element solutions of the second kind Fredholm integral equation are established.In the case of a smooth kernel, iterative corrections are made for the finite element solutions (m degree), the accuracy can be improved from O (hm+1) to O (h3m+3,).
