摘要
对结构稳定或动力分析中常遇到的函数行列式特征根的求解问题，在假定有实根的前提下，提供了一种有效而简便的计算机方法，能够求解任意阶数的函数行列式和任意个数的实特征根，并编出了实用的ＦＯＲＴＲＡＮ７７程序，算例表明，该法计算结果精度高，通用性强，应用简便。
For solving the eigenvalues of functional determinants usually met instructure stability and dynamic analyses,an effective and convenient computer method is introduced and the practicaI FORTRAN77 program is made up in this paper. The method issuited to solve arbitrary order of functional determinants and give expected numbers of eigen-values.The examples show that the method has high precision and is simple to use
