摘要
本文针对二维波动方程的反演问题，提出了一种新的迭代方法。该方法是一种牛顿型选代，并且每步迭代都利用古洪诺夫正则化方法克服反问题的不适定性，因此具有良好的数值稳定性．文中给出了数值仿真实例说明了本方法的可行性及有效性。
Anew iterative method is proposed for the inverse problem of 2-D acoustic equation. As a kind of Newton-type iteration, the method overcomes the ill-posed of inverseproblem by Tikhonov's regularization method in each iterative step and has a good numericalstability.The Numerical results show that this method is feasible and effeCtive.
