论文摘要
我们提出了一种分析模型,用于使用粗糙的势能表面(PES)来计算单原子液体的热力学特性。 PES转化为等效的简单谐波振荡器。该模型在不采用任何可调节参数的情况下与模拟液体液体的实验熵,热容量和融合热和蒸发数据紧密相吻合。此外,它为Richard熔化规则提供了简单的物理解释,并为Trouton蒸发规则提供了依赖物质的校正。
We present an analytical model for calculating the thermodynamic properties of monoatomic liquids using a rough potential energy surface (PES). The PES is transformed into an equivalent simple harmonic oscillator. Without employing any adjustable parameters, the model agrees closely with experimental entropy, heat capacity, and latent heat of fusion and vaporization data for monatomic liquids. In addition, it offers a simple, physical explanation for Richard Melting rule, and provides a material-dependent correction to Trouton Vaporization rule.
