摘要: 液滴滴落在垂直激励的液体表面,有可能会在表面停留很长时间.本文对该现象进行了实验研究,分析了多种因素 对液滴存活时间的影响.结果发现: 当驱动频率、驱动振幅、液滴滴落高度处于适当的值时,可以使得液滴存活较长的时间,并且液滴的存活时间会随着液体浓度的改变而改变.

Abstract: Drop in liquid surface of vertical excitation is possible to stay in the surface for a long time. Based on the experiment,we study the effects of various factors on the survival time of the droplets. The results show that the droplets may survive for a long time under appropriate values of the driving frequency,driving amplitude and liquid drop height. In addition,the survival time of the droplets depends on the liquid concentration.

Key words: vertical excitation, droplet, survival time
