For instance , to him the generalized stiffness of a system was the stiffness of a single spring which , when subjected to an extension equal to the generalized displacement , stored the same amount of potential ( strain ) energy as the actual system when deformed in a mode with the same generalized displacement 例如,他的意識(shí)普遍的是系統(tǒng)性能的一個(gè)春天,當(dāng)受到展延等于普遍遷移、存儲(chǔ)同等數(shù)量的潛力(品種)作為能源的實(shí)際系統(tǒng)在變形的方式同普遍流離失所
