浸润现象,对我们来说并不陌生.在一干净的玻璃上滴上一滴水,水珠会逐渐散开.我们就说:水浸润了玻璃.相反,如果在玻璃上滴上的是水银,水银则始终聚在一起,不会散开.我们就说:水银不能浸润玻璃.早在1805年,英国科学家T.Young就研究了这种现象.他根据水平方向的力学平衡,得到浸润现象与气体、固体、液体之间表面张力的关系式.物理学家对于浸润问题重新感兴趣,是因为1977年Cahn从理论上预言了从部分浸润到完全浸润状态是一种相变.1980年,Moldorer和Cahn用实验证实了浸润相变的存在.他们在一容器中注入甲醇和环己烷,构
Infiltration, is no stranger to us .A drop of water in a clean glass, water droplets will gradually spread.We say: water infiltrated the glass.On the contrary, if the drop is on the glass of mercury, Mercury will always come together and will not disperse, and we say: Mercury can not infiltrate glass, as early as 1805 by T. Young, a British scientist, who studied the phenomenon by the mechanical equilibrium in the horizontal direction, The relationship between the surface tension of gas, solid, and liquid Physicists are once again interested in the problem of soaking because, in 1977, Cahn theoretically predicted a phase transition from a partial to a complete wet state. In 1980, Moldorer And Cahn experimentally confirmed the presence of wetting phase transitions by injecting methanol and cyclohexane in a vessel,
