[交流] 【交流】系统熵、构型熵、过剩熵、双体相关熵有什么关系呢?

系统熵、构型熵、过剩熵、双体相关熵有什么关系呢?有没有具体的定量关系呢?同一体系,双体相关熵大概占过剩熵的多少呢?很多文献都是这些参数的应用,没有一些原理的东西,各位有没有这方面的资料呢?请大家给推荐点书或文献吧,谢谢!有些文献的表述也不太一致,不知引用哪篇权威,比较困惑。这方面的初学者,很资深的专家就不要来说这是什么民科帖了,给初学者一点空间!做材料的,对统计物理理解的比较肤浅。
PS 发文章时,计算出来的一些参量画成图了,这些参量还要用表格的形式精确列出来吗?
the total thermodynamic excess entropy sex, which accounts for all intermolecular (two-, three-,and higher-body)correlations, including translational contributions related to center-of-mass positional correlations and orientational contributions associated with correlations between the orientations of neighboring molecules.(全是构型?)

Under any certain macro-state, changes of the spatial location distribution of large number of particles in system lead to many microscopic state, which is called the configurational chaos degree. Entropy provided by the configurational chaos degree is called excess entropy, that is, S = klnΩ.

The excess entropy Se, the difference between the system thermodynamic entropy(就是系统熵?) and that of the equivalent ideal gas, is a measure of the number of accessible configurations of the system .可以有偶分布函数计算出,只是由构型引起的?        

It is found that a liquid’s configurational entropy would not be proportional to its excess entropy over the crystal phase
Sexc = S(exc;vib)+S(conf) Svib振动自旋?应该属于构型?  Sconf = kB lnΩ

以前只知道熵的名目繁多
具体的内容
还真不知道
