摘要：

Acoustically induced cavitation at 20 kHz is observed by means of high speed CCD recording at a framerate of 2250 per second. Using digital image processing the bubbles' trajectories are reconstructed. The experimental data reveal that collision and coalescence of bubbles is a predominant phenomenon that limits their individual lifetime. Measurements of bubble sizes and velocities are in agreement with previous results. (C) 2001 Published by Elsevier Science B.V.
