While structure damage is reflected by the change of stiffness . so the curvature may detect the damage of structure 而结构发生损伤就表现在刚度变化上,所以结构的损伤识别可以用曲率模态的变化来判别。
While structured p2p networks can provide search efficiency and scalability by deploying identifier - based search mechanism , they fail to support flexible multi - keyword search like unstructured p2p networks do 如gnutella和kazaa等基于无结构对等网络的应用采用基于泛洪的搜索机制,虽然可以支持灵活的查询,但搜索的效率和可扩展性都较低。
This is structure control commonly , traditional design method is controlling structural vibration by restriction . while structure vibration control desingn method is the main way by rorce controlling . structure vibration . nearly some years , structrure control dcsingn idea has been put forward in civil engineering 一个突破传统设计的新方法和新概念被提出来了,这就是控制结构。一般说来,传统的设计方法是以约束来控制结构的振动,而结构振动控制设计方法是以力来控制结构振动为主的方法。
