The total noise changes complexly. When the bubblecavitation turns on the sheet cavitation, the total noise will reduce suddenly although the cavitation number becomes smaller.
噪声总声级的变化较为复杂，由泡空化状态转换到片空化状态，空化数虽然减小，但总声级会突然降低。

The oscillation of a laser-generated cavitationbubble near a solid boundary is investigated with a home-made optical fiber sensor.
采用自行研制的光纤传感器研究了激光等离子体空泡在固壁面附近的脉动特性。

The numerical results show that for a small cavitationbubble near a rigid wall effects of surface tension on its collapsing behavior are very significant.
