The method of lifetime measurement has been used to investigate spontaneous cavitation kinetics in superheated liquid argon in weak acoustic fields. It is shown that acoustic cavitation may proceed both by the mechanism of homogeneous nucleation of the vapor phase and by way of 'build-up' of vapor bubbles generated by high-energy particles or the action of some other external factor. Acoustic cavitation thresholds are adequately described by homogeneous nucleation theory.
寿命测量方法已被用于研究弱声场中过热液氩的自发空化动力学。结果表明，声空化可能通过气相均匀成核机制进行，也可能通过高能粒子产生的蒸汽泡“积聚”或其他外部因素的作用进行。声空化阈值可以用均匀成核理论充分描述。
