给出了利用超声雾化技术从乙醇-水溶液中选择性分离乙醇的实验数据。在10 °C下，从含有少量摩尔%乙醇-水溶液的溶液中可以直接得到纯乙醇，这可以用毛细管波的参数衰减不稳定性来解释，在这种情况下，声能发生了高度的局部化和积累，导致了超声雾化。也就是说，参数衰变不稳定性将纵波的能量凝聚在毛细波高度局域化的表面区，并导致超声雾化。
We show the experimental data of selective ethanol separation from ethanol–water solution, using ultrasonic atomization. Pure ethanol could be obtained directly from a solution with several mol% ethanol–water solution at 10 °C. This result can be explained in terms of parametric decay instability of capillary wave, in which high localization and accumulation of acoustic energy occur, leading to ultrasonic atomization. That is, parametric decay instability condenses the energy of longitudinal waves in a highly localized surface area of the capillary wave, and causes ultrasonic atomization.
