标题： Influence of attractive parts of interaction potentials on critical point parameters

摘要： 我们研究粒子间势的微观特性如何影响宏观临界点参数。 我们的分析计算基于连续多粒子系统的单元模型。 我们探讨了由Morse势和Curie-Weiss型势描述的两种类型的对相互作用。 对于Morse流体，我们给出了与碱金属钠（Na）和钾（K）对应的微观参数的数值结果。 计算出的液态Na和K的无量纲临界点参数，以有量纲单位表示，可以直接与现有的实验和模拟数据进行比较。 对于具有竞争相互作用的Curie-Weiss单元模型，该模型表现出一系列的一阶相变，我们研究了前三个临界点的临界参数。 我们通过改变Morse势的吸引部分和Curie-Weiss吸引力强度来分析我们的结果，提供了这些微观特性如何改变临界点坐标的见解。 显示英文摘要

摘要： We investigate how microscopic features of interparticle potentials influence macroscopic critical point parameters. Our analytical calculations are based on the cell model for continuous many-particle systems. We explore two types of pair interactions described by the Morse potential and a Curie-Weiss-type potential. For Morse fluids, we present numerical results obtained with microscopic parameters corresponding to the alkali metals sodium (Na) and potassium (K). The calculated dimensionless critical point parameters for liquid Na and K, expressed in dimensional units, allow for direct comparison with available experimental and simulation data. For the Curie-Weiss cell model with competing interactions, which exhibits a sequence of first-order phase transitions, we examine the critical parameters for the first three critical points. We analyze our results by varying the attractive part of the Morse potential and the Curie-Weiss attraction strength, providing insights into how these microscopic characteristics change critical point coordinates.
