论文摘要

在这项工作中,我们研究了硬核有吸引力的Yukawa流体(HCAYF)的液体蒸气平衡与类似Ising类型的晶格气体(LG)模型之间的全球同构。讨论了全局同构转换的适用性及其参数对Yukawa电位筛选长度的依赖性。这些参数既决定了液体蒸气双座的直径的斜率,又决定了Zeno元素,这是流体 - 晶格气体同构的核心成分。我们将Zeno-element参数与病毒Zeno-line参数进行比较,这些参数通常用于文献中,以制定通用状态的广义定律。事实证明,当相互作用势变得太短范围时,ZENO元素参数似乎对液态状态不稳定性敏感,而病毒元素没有显示出与Hcayf的特定特异性有关的任何特殊性。

In this work we study the global isomorphism between the liquid-vapor equilibrium of the hard-core attractive Yukawa fluid (HCAYF) and that of the Lattice Gas (LG) model of the Ising-like type. The applicability of the global isomorphism transformation and dependence of its parameters on the screening length of the Yukawa potential are discussed. These parameters determine both the slope of the rectilinear diameter of the liquid-vapor binodal and the Zeno-element which are the core ingredients of the fluid - lattice gas isomorphism. We compare the Zeno-element parameters with the virial Zeno-line parameters which are commonly used in the literature for the formulation of generalized law of the correspondent states. It is demonstrated that the Zeno-element parameters appear to be sensitive to the liquid state instability when the interaction potential becomes too short-ranged while the virial ones do not show any peculiarities connected with this specific of the HCAYF.
