摘要
导出了方程 ·(k u) =0 的正问题的边界元算法 ,并在此基础上导出了求解k的参数识别问题的一种迭代算法。算例表明 ,这种方法是正确有效的 ,并具有对于初值依赖程度小的优点。
An algorithm for solving the equation ·(k u)=0 has been derived by means of BEM. Based on it an iterative process has been introduced for solving the parameter identification problem included in the equation. An example given here shows that its dependence on the initial values is small.
