研究了声空化噪声特性与液体粘度之间的关系，探讨了基于声空化动力学的粘度测量方法的可行性。测量并比较了水、水-甘油混合物和水-表面活性剂混合物中气泡的声发射谱。结果发现，所有谐波功率之和与宽带噪声功率之比是粘性的良好指标。
The relationship between the characteristics of the acoustic cavitation noise and the viscosity of the liquids is investigated to consider the viability of the viscosity measurement based on the acoustic cavitation dynamics. The spectra of acoustic emission from the bubbles generated in water, water-glycerol mixture, and water-surfactant mixture are measured and compared. As a result, it is found that the ratio between sum of all the power of harmonics and the power of the broadband noise would be a good indicator of the viscosity.
