Abstract

The distribution of the density of the adsorbate inside the transition region of the liquid–vapor interface in a slit pore, in which the density of the substance varies both along the pore width and along the transition region between the vapor and the liquid, has been investigated. Equilibrium molecular distributions at the phase boundary are described in the framework of the discrete-continuum molecular theory in the quasi-chemical approximation, which reflects the effects of direct correlations of interacting particles. The interaction of particles is described by a pair potential of the Lennard–Jones type. The self-consistency of the description of the rough meniscus profile using kinetic (through the equality of the calculated desorption and condensation rates) and equilibrium equations has been established. The probability of the formation of a liquid phase bridge between the pore walls in slotlike porous systems is considered depending on the length of the section, the pore width and the energy of the walls.

狭缝状孔隙中平衡半月形的自洽描述及其形成的大小依赖性分析

摘要

狭缝中液-气界面过渡区域内被吸附物的密度分布，其中物质的密度不仅沿孔隙宽度而且沿蒸汽与液体之间的过渡区域变化。调查。在离散连续谱分子理论的准化学近似中描述了相界处的平衡分子分布，该理论反映了相互作用粒子之间直接相关的影响。粒子的相互作用由Lennard-Jones型的偶对势来描述。建立了动力学（通过计算出的解吸率和冷凝率的相等性）和平衡方程描述的粗糙弯月面轮廓的自洽性。
