摘要
本文采用二维Collins模型,以氙元素为例,在考虑4-原子和非简谐振动的情况下,计算了二维系统的热力学函数,讨论了粒子密度、4-原子、非简谐振动对相变点的影响,较定量的研究了非简谐振动对热容量影响的大小.结果与实际三维情形极为相似.
Using two-dimensional Collins Model, taking element Xe for example, and considering 4-atom and anharmonic vibration, this article gives calculations about the thermodynamical function of two-dimensional system, discusses the influence of 4-atom, particle density and anharmonic vibration on the phase transition point, and investigates quantitively the influence of anharmonic vibration on heat-capacity. The results of these studies in two-dimensional system are very similar to those in three-dimensional system.
