Instability of interfaces of gas bubbles in liquids under acoustic excitation with dual frequency is theoretically investigated. The critical bubble radii dividing stable and unstable regions of bubbles under dual-frequency acoustic excitation are strongly affected by the amplitudes of dual-frequency acoustic excitation rather than the frequencies of dual-frequency excitation. The limitation of the proposed model is also discussed with demonstrating examples.
从理论上研究了双频声激发下液体中气泡界面的不稳定性。双频声激发下划分气泡稳定和不稳定区域的临界气泡半径受双频声激发的幅度影响较大，而不是双频激发的频率。还通过示例讨论了所提出模型的局限性。
