摘要：

讨论怎样理解子的配分函数的物理意义,以及它和系统的配分函数在计算热力学函数中的作用,指出它既不是系统的广延性质,也不是系统的强度性质,只是联系系统热力学函数与微观信息的纽带。

关键词: 子的配分函数, 正则配分函数, 热力学函数, 强度性质, 广延性质

Abstract:

We discussed the physical meaning of the molecular partition function, and the role of both the molecular partition function and the partition function of the system in the calculation of the thermodynamic properties.It was shown that the molecular partition function is neither an extensive property nor an intensive one, but only a tie to connect the thermodynamic properties with the microscopic information of the system.

Key words: Molecular partition function, Canonical partition function, Thermodynamic function, Intensive property, Extensive property
