我们研究了声脉冲成核气泡的动力学。我们测量气泡的半径作为时间的函数，直到它崩溃并产生第二个气泡。对于10 - 70mbar范围内的静压，结果与经典的瑞利方程非常吻合。第二个气泡的能量是第一个气泡的5 - 10%。
We have studied the dynamics of bubbles which are nucleated with a sound pulse. We measure the radius of the bubble as a function of time until it collapses and gives birth to a second bubble. For static pressures in the range 10–70 mbars, the results are in very good agreement with the classical Rayleigh equation. The energy of the second bubble is 5 to 10% of the first one.
