WETTING TRANSITIONS OF A SIMPLE FLUID CONFINED BETWEEN DIFFERENT PARALLEL WALLS
具有不同作用势的两平行墙间流体的浸润相变

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.
