| 摘 要： | 本从实验的角度出发,对超声复合振动系统中细长杆的“局部共振”现象进行了较为精确的测量,主要研究了细杆长度与谐振频率之间的关系,超声振子对“局部共振”的影响,以及“局部共振”中细杆长度对振幅的影响,从而为深入研究“局部共振”现象产生的机理提供了更多的依据。

| Abstract: | Based on a series of experiments, the phenomenon of "local resonance" in compound ultrasonic vibration systems is studied. Experiments include relations of the length of thin threading beam to frequency of resonance, and the effect of the ultrasonic vibration systems on the phenomena of "local resonance", and the relation of the length of the beam to amplitude. The experiments may help in the understanding of the mechanism of "local resonance". |
