水中脉冲放电产生的气泡可以发射大量脉冲声波。气泡行为对于电声分析非常重要。本文展示了含等离子体气泡在不同极性脉冲放电下的行为的高速照片，包括单个负气泡、单个正气泡和双极性气泡。单气泡结果表明，正极放电的电气泡能量转移率高于负极放电的电气泡能量转移率。正气泡比负气泡具有更长的振荡周期和更低的基本频率。对于双极气泡，无论电极之间的间隙距离有多长，两个气泡之间的相互作用都会影响它们自身的行为，并且也会降低电气泡的能量转换效率和声波振幅。另外有趣的是，负泡虽然能量比正泡低很多，但是却振荡了两次，而且第二个周期结束时负泡破裂的时间几乎与正泡重合。最后，正泡沫比负泡沫更快破碎和消失。
Bubbles generated by a pulsed discharge in water can emit extensive pulsed acoustic waves. The bubble behavior is quite important for the electroacoustic analysis. This paper presents the high-speed photographs of the plasma-containing bubble behavior under the pulsed discharges of different polarities, including a single negative bubble, single positive bubble, and bipolar bubbles. The single bubble results show that the electrobubble energy transition rate of the positive discharge is higher than that of the negative discharge. The positive bubble has longer oscillation period and lower fundamental frequency than the negative one. For the bipolar bubbles, interaction between the two bubbles influences their own behavior, irrespectively of how long the gap distance between the electrodes is, and decreases the electrobubble energy transition efficiency and the acoustic wave amplitude as well. It is also interesting that the negative bubble oscillates twice, although its energy is much lower than that of the positive bubble, and the time of the negative bubble collapse at the end of the second period almost coincides with that of the positive bubble. Finally, the positive bubble breaks into pieces and vanishes faster than the negative bubble.
