The fact that for a structure with certain extent of damage, the natural frequencies change accordingly compared to its primary intact structure, motivates to propose a novel concept of natural frequency vector.
基于损伤前后结构固有频率的变化,引入了固有频率向量及固有频率向量置信准则的概念,提出了基于固有频率向量的结构损伤检测方法。
4) axial natural frequency
轴向固有频率
5) natural frequency measurement
固有频率的测量
6) frequency criterion
频率准则

New necessary and sufficient condition for the existence of aLyapunov function of Lurie form is obtained,and thus a frequency criterion for absolute stabilityis drawn,which improves the results obtained by Rapoport and Kamenetski
得出了Ｌｕｒｉｅ型Ｌｙａｐｕｎｏｖ函数存在的充要条件，并由此引导出绝对稳定性的新频率准则，它改进了文献［１］，［２］中的新近结果。
补充资料：固有频率
