摘　　要：本文给出了一种求解波动方程反演问题的“多目标函数法”.这种方法简单、有效,并具有明确的物理意义.对于三维问题的程序化它有很强的优越性.We introduce a multi-cost-functional method for solving inverse problems of wave equations. This method has its simplicity, efficiency and good physical interpretation. It has the advantage of being programmed for two-or three-(space)dimen-sional problems as well as for one-dimensional problems.

关 键 词：波动方程 反问题 多目标函数法
