| 摘 要： | 推广了Ｂｅｒｎａｒｄ和Ｂｒｏｎｏｗｉｃｋｉ针对自伴系统提出的模态展开特征灵敏度方法。从最小能量逆出发，直接导出一族模态法，它适用于异导或等导重根的特征矢导的计算。模态法和的模态法是本族的一个子集。

| Abstract: | eneralizations are made to the modal expansion eigensensitivity procedure for self-ad joint systems originally formulated by Bernard and Bronouwicki. A family of modal methods for the calculation of eigehvector derivatives associated with repeated roots and repeated root derivatives is developed from the minimum energy inverse. The family contains the modal and modified modal methods as a subset. |
