波动方程系数反问题

An Evaluation Method to Determine Inverse Problem of Wave Equation

讨论了一维波动方程系数反演的一种求解方法，将解进行一阶渐近展开，证明了反问题解的存在唯一性，并得到近似解的渐近阶估计。

An evaluation method to determine inverse problem of wave equation is discussed,which is a gradual expansion in one-order approaching to the solution. We prove the existence and uniqueness of solution for inverse problem and obtain an estimation with gradual order to the approximate solution.
