摘要
用解析方法讨论了当两平行墙对流体施加不同的作用势时流体的浸润相变。系统的状态很敏感地依赖于两墙的作用势和两墙间距离的大小。即使两墙差别很小,在一定条件下仍可发生浸润一墙而不浸润另一墙的现象。系统中发生的浸润相变可能是一级的,也可能是二级的。
By means of dynamics approach, the wetting transitions of a simple fluid confined between parallel walls that exert different surface fields have been investigated. The states of the system are sensitive to the surface fields and wall separation. In some cases, even if the difference of two walls is very small, the phenomenon that one wall is wet and the other is non-wet may occur. The wetting transitions may be first order of second order.
