While structure damage is reflected by the change of stiffness . so the curvature may detect the damage of structure 而結(jié)構(gòu)發(fā)生損傷就表現(xiàn)在剛度變化上,所以結(jié)構(gòu)的損傷識(shí)別可以用曲率模態(tài)的變化來判別。
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等基于無結(jié)構(gòu)對(duì)等網(wǎng)絡(luò)的應(yīng)用采用基于泛洪的搜索機(jī)制,雖然可以支持靈活的查詢,但搜索的效率和可擴(kuò)展性都較低。
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 一個(gè)突破傳統(tǒng)設(shè)計(jì)的新方法和新概念被提出來了,這就是控制結(jié)構(gòu)。一般說來,傳統(tǒng)的設(shè)計(jì)方法是以約束來控制結(jié)構(gòu)的振動(dòng),而結(jié)構(gòu)振動(dòng)控制設(shè)計(jì)方法是以力來控制結(jié)構(gòu)振動(dòng)為主的方法。
