摘要
对光滑固体表面下悬挂的液滴进行了理论分析,建立了悬垂液滴特征尺寸R和H与液滴表面张力σL和固液界面润湿角θ之间的关系式,计算发现对于特定的ρ,σL,θ值,液滴质量m与固液界面润湿半径R、液滴高度H满足特殊的曲线关系.利用此关系可以同时测量液滴的表面张力σL以及固液界面间的润湿角θ.
Liquid drop suspended under a solid plane is analyzed and reproduced by calculation. It is found that the shape of a liquid drop is only determined by liquid density p, surface tension σL wetting angle θ and drop mass m, which can be used to measure liquid surface tension and wetting angle simultaneously.
