摘要
本文研究了杆的有阻尼离散模型的模态反问题，给出了该模型的两个不共轭复模态问的关系，得出了解存在且唯一的条件．文中构造了算法，通过算例说明了初始数据的精度对解的影响。
In this paper,the inverse mode problem of a discrete damped model of a rod is studied,The relation between the two modes of the model is found. The correspondant conditions forthe existence and uniquaness of the solutions of the problem,as well as the solving methods,are specified.Computational examples are given.
