在已提出的求解特征值反问题逆摄动法及其摄动参数ε计算公式的基础上 ,给出了可视化人机交互选取逆摄动参数ε的方法 .它便于发挥工程技术人员的作用 ,有利于处理复杂工程系统的频率禁区问题 .编制了相应的软件 .

On the basis of the inverse perturbation method and the formulas of parameter ε which have been developed for solving inverse eigenvalue problems by authors, the visualized interactive method for determining inverse perturbation parameter ε is introduced. It contributes to giving full play to technicians′ function and dealing with the forbidden zone problems of the frequency for the complicated engineering systems. The software realizing the method is programmed in this paper. An example shows that the method is feasible and effective.
