摘要
本文利用特征值函数及其一阶导函数与设计参数的关系图,讨论了设计参数对特征值分区的影响,以及密频现象发生的位置和程度。并且运用特征向量函数及其一阶导函数与设计参数的关系图,分析上述密频发生时,特征向量的不稳定性及发生跳跃的程度。
By using relation graph of eigenvalue function and its derivative, this paper the effect of design parameters on eigenvalues partition, and the location and degree of dense frequency phenomenon. In addition, it analyzes the occurence of the above frequency and the instability of characteristic vector and jumping by using relation graph of eigenvector function and its derivative.
