定义了一类润湿转变的密度泛函模型。导出了跃迁高于一阶的必要条件。在两个模型场变量的平面中的润湿过渡的轨迹被确定，在该轨迹上存在一阶和高阶的状态，包括无限阶的过渡。观察到的行为是合理的，通过一个不同的，但相关的，分析可溶的模型。
A class of density-functional models for wetting transitions is defined. A necessary condition for the transitions to be of higher than first order is derived. A locus of wetting transitions in the plane of two model field variables is determined on which there are states of first-order and of higher-order, including infinite-order, transitions. The observed behavior is rationalized via a different but related, analytically soluble model.
