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. 通过对几种不同的隔振形式的分析，得到了扭转振动的固有频率与线性振动的固有频率之间的关系。
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. 对激励由凸集合建模的线性振动系统提出了响应集的概念，将数学上的微分包含问题简化为求解多自由度振动系统的响应集问题。
