例句與造句

1. because of these characteristics, the variable stiffness sma bearing used in rotor system can be designed, and then the stiffness of system can be varied by active control technology when the rotate speed of system is near the critical rotate speed to reduce the maximum vibration amplitude of rotor system
   利用這些特性可以設(shè)計(jì)出用于轉(zhuǎn)子系統(tǒng)的可變剛度支承，通過結(jié)合主動控制技術(shù)，在臨界轉(zhuǎn)速附近改變系統(tǒng)剛度，從而降低系統(tǒng)在臨界轉(zhuǎn)速時(shí)的最大振幅。本文研究利用形狀記憶合金對轉(zhuǎn)子系統(tǒng)振動進(jìn)行主動控制。
2. It's difficult to find maximum vibration in a sentence. 用maximum vibration造句挺難的
