对于第一类液滴(尺度远大于界面层的厚度),无论是远离固体壁面的液体球或附着在壁面上的球冠,其内外压力差(简称“附加压力”)均适用经典Laplace公式,并且特别对球冠情况给出了一种新的整体性证明.还澄清有关争论:指出[曹治党、郭愚1999物理学报481823]一文对附壁面第一类液体球冠所推导出的附加压力与接触角有关的公式是错误的,而[闵敬春2002物理学报512730]是正确的。
For the first type of droplets (scale is much larger than the thickness of the interface layer), whether it is a liquid ball far away from the solid wall or a spherical cap attached to the wall surface, the pressure difference between inside and outside (abbreviated as “additional pressure”) applies to classical Laplace Formula, and in particular gives a new holistic proof of the situation of the spherical crown. Also clarify the debate: pointed out [Cao Zhi party, Guo Yu 1999 Physics 481823] article attached to the first type of liquid spherical crown deduced The additional pressure and contact angle of the formula is wrong, and [Minjing 2002 Physical 512730] is correct.
