您要查找的是不是:
- lower mode vibration 低次模振动,低音调振动
- The impact of piping to supports can excite higher eigenmode and results in an energy transfer from dominant lower modes into higher modes of vibration. 管道与支座的碰撞激发出系统的高阶振型,导致系统能量由低阶模态向高阶模态转移。
- A novel back-ward wave oscillator(BWO) with photonic band gap(PBG) structure is proposed. The PBG structure offers mode-confining and choosing mechanisms,restraining the lower modes and making the BWO operate at the higher modes. 提出了一种新型的具有光子晶体带隙(PBG)结构的返波振荡器(BWO),利用PBG禁带对BWO工作及输出微波模式进行调制,抑制低次模式,工作在高次模式。
