本文实验研究了不同脉冲宽度的820kHZ超声波的空化效应，结果得出，空化致自基产量随脉冲宽度及声强呈现规律性变化，尤其观察到了“脉冲空化峰”现象．本文从液面受迫振动角度提出混响场中“脉冲空化峰”现象的机制．
In this paper, the cavitation effect of 820kHZ ultrasonic waves with different pulse widths was studied experimentally. The results showed that the cavitation induced self-basis yield showed a regular change with pulse width and sound intensity, especially the phenomenon of “pulse cavitation peak” was observed. In this paper, the mechanism of “pulse cavitation peak” phenomenon in reverberation field is proposed from the perspective of forced liquid level vibration.
