本文回顾了稀泡状液体的声学理论，并通过考虑液体可压缩性对气泡固有频率的影响，对频散关系进行了修正。修改后的理论示出更准确地预测超声波的衰减测量的趋势。与这种高频波的模型的局限性进行了讨论。(C)2009年美国声学学会
The theory of the acoustics of dilute bubbly liquids is reviewed, and the dispersion relation is modified by including the effect of liquid compressibility on the natural frequency of the bubbles. The modified theory is shown to more accurately predict the trend in measured attenuation of ultrasonic waves. The model limitations associated with such high-frequency waves are discussed.
