Abstract

This work acquaints readers with the contemporary apparatus of chemical thermodynamics in the surface and colloid science. The J potential is a new parameter, which represents a series of thermodynamic potentials and is determined for fluid systems as a grand thermodynamic potential in combination with the product of a system volume and some pressure \(p{\kern 1pt} '.\) A classification has been given with discrimination of the classical J potential (when \(p{\kern 1pt} '\) is an external pressure) and special J potentials (at other values of \(p{\kern 1pt} '\)). For both classes, hybrid types of the potentials have been considered, when chemical potentials are chosen as variables for one group of components, while the number of molecules or moles is selected as such for another group. The main attention has been focused on the application of all considered types of the J potential to a system containing a planar thin film. In particular, a case has been analyzed in which the pressure in the mother phase of a thin film plays the role of \(p{\kern 1pt} '\). Resulting fundamental equations have been formulated in terms of the disjoining pressure.

关于薄膜的热力学。J电位

摘要

这项工作使读者熟悉表面和胶体科学中化学热力学的当代装置。所述Ĵ电位是一个新的参数，该参数表示一系列热力学势的和被确定为流体系统如结合系统卷的产物和一些压力隆重热力学势\（P {\克恩1点}”。\）给出了区分经典J势（当\（p {\ kern 1pt}'\）是外部压力时）和特殊J势（在\（p {\ kern 1pt}'\的其他值）的分类。）。两个类，混合类型的电势的已被考虑，当化学势被选作为一组的部件的变量，而分子或摩尔数被选择为这样另一组。主要的注意力集中在将所有已考虑类型的J电位应用于包含平面薄膜的系统上。特别地，已经分析了在薄膜的母相中的压力起\（p {\ kern 1pt}'\）的作用的情况。得出的基本方程式是根据分离压力建立的。
