To widen the range of the plane gates, it is very much important for plane gates to study hemline cavitation and solving measure.
为了扩大其适用范围，对阀门底缘空化特性及改善措施进行综合研究是很有十分重要的。

The structure of the cavitation bubble cloud is featured by the regional distribution of cavitation bubbles. Within a range of ultrasonic power levels the structure remains stable.
空化泡群的结构以空化泡在声场中的区域化分布为特征。在一定功率范围内空化泡群的结构保持稳定。

With the increase of driving frequency, the initial radii range of cavitation bubbles decrease, and the oscillation intensity reduces.
