When the exhaust valve is closed, the gas with the bubbleoscillation reduces, causing the bubble impulse lower the pressure impulse obviously.
排气阀门的关闭直接造成参与气泡振荡的气体质量的减少，第二气泡脉冲相对主脉冲明显减小。

The oscillation of a laser-generated cavitation bubble 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 radius period of oscillation of the bubble and the water pressures are calculated numerically with Runge-Kutta method. The calculating results are unanimous with that of experiments.
