范德华在研究温度高于临界时从液体到蒸汽状态的连续变化时，提出了这样一个理论：在液体和它的蒸汽之间的边界上，从一种状态到另一种状态并没有突然的变化，而是存在一个过渡层，在这个过渡层中，密度和其他性质从液体的状态逐渐变化到蒸汽的状态。物质各相之间连续过渡的概念在表面现象理论的发展中得到了非常广泛的应用，如表面张力、吸附等。例如，在处理气体吸附理论时，欧肯认为过渡层是一种微型大气，分子通过某种“作用ata”被吸引到表面
In his studies of the continuous change from the liquid to the vapor state, at temperatures above the critical, van der Waals developed the theory that at theboundary between a liquid and its vaporthere is not an abrupt change from one state to the other, but rather that a transition layer exists in which the density and other properties vary grad-ually from those of the liquid to those of the vapor. This idea of the continuous transition between phases of matter has been applied very generally in the development of theories of surface phenomena, such as surface tension, adsorption, etc. Eucken, 1 for example, in dealing with the theory of adsorption of gases, considers that the transition layer is a sort of miniature atmosphere, the molecules being attracted to the surface by some kind of “action ata
