摘　　要：在用传递矩阵法1求解多圆盘转子系统的特征值问题时,经常会出现数值不稳定和误差较大的现象。将求传递矩阵特征值的割线法进行改进,使得计算结果的误差变得较小,计算结果的可靠性增强。最后通过实例证实本算法的优越性。The instability and error of numerical value and error phenomenon may be often met When resolving eigenvalue of disk rotor system by using the method of transfer matrix. This paper mainly improved the secant method t on eigenvalue of transfer matrix. The result shows that the method given can make error smaller and its credibility became better also. Finally, its superiority is proved by a example.
