摘要： 发现硅油液滴能够停留在竖直振动的硅油液面上,通过等厚干涉实验说明液滴和液面间存在空气薄膜,分析空气膜形状的变化过程,并依此建立简化模型论述空气膜阻止液滴与液面融合的原理.实验构造了浸没在硅油液面下的硅油液滴,建立理论模型估算空气膜的平均厚度,并与实验估测值对比.本文对多个液滴在液面上呼吸模式的振动现象作了描述和解释.
关键词: 液滴, 液面, 竖直振动, 不融合, 空气膜
Abstract: The phenomenon that silicon oil drops stay on the vibrating liquid surface is found.Experiment of equal thickness interference indicates the existent of air film.Based on the analysis of the air film＇s transformation,a simplified model is proposed to explain how the air film inhibited the coalescing of drops and liquid surface.Drops underneath the liquid surface are observed and theoretical model is founded to calculate the thickness of air films,which is also compared with the experimental value.The paper also describes and explains the breath-mode vibrating phenomenon of multiple drops.
Key words: drop, liquid surface, vertical vibrating, noncoalescing phenomenon, air film
