摘要：
In this paper, we report on a strategy for computing the numerical approximate solution for a class of ill-posed operator equations in Hilbert spaces: K : E -> F,Kf = g. This approach is a combination of Tikhonov regularization method and the finite rank approximation of K*K. Finally, numerical results are given to show the effectiveness of this method.
