| 摘 要： | 利用Collins模型,以氙为例,计算了非简谐振动情况下二维Collins模型系统的热力学函数,讨论了非简谐振动对二维流体的密度、定压膨胀系数和等温压缩系数、热容量等热力学量的影响.结果表明,用Collins模型研究液体的热力学性质时,只要考虑到原子相互作用势和作非简谐振动,所得的结果就与实际液体的情况有相同的变化趋势.

| Abstract: | In this paper, using the Collins model and taking Xe as an example, the authors calculate the thermodynamic functions of two-dimensional Collins model system, discuss the influences of unharmonic oscillation on the density, coefficient of constant pressure expansion, coefficient of constant temperature compression and heat capacity. The results show that when using Collins model to study the thermodynamic properties of liquid, as long as they consider the interaction potential energy and unharmonic oscillation of atoms, they can obtain the results which have the same changing tendency as the results of actual liquid. |
