By analysing some different types of isolating configurations, the relations between the natural frequency of rotational vibration and that of the linear vibration have been found. 通過對幾種不同的隔振形式的分析，得到了扭轉振動的固有頻率與線性振動的固有頻率之間的關係。
A support hyperplane method is presented to find the response set defined for a linear time invariant vibration system under the excitations modeled by some convex sets. 對激勵由凸集合建模的線性振動系統提出了響應集的概念，將數學上的微分包含問題簡化為求解多自由度振動系統的響應集問題。
