【交流】系統(tǒng)熵、構(gòu)型熵、過剩熵、雙體相關(guān)熵有什么關(guān)系呢?

系統(tǒng)熵、構(gòu)型熵、過剩熵、雙體相關(guān)熵有什么關(guān)系呢?有沒有具體的定量關(guān)系呢?同一體系,雙體相關(guān)熵大概占過剩熵的多少呢?很多文獻(xiàn)都是這些參數(shù)的應(yīng)用,沒有一些原理的東西,各位有沒有這方面的資料呢?請(qǐng)大家給推薦點(diǎn)書或文獻(xiàn)吧,謝謝!有些文獻(xiàn)的表述也不太一致,不知引用哪篇權(quán)威,比較困惑。這方面的初學(xué)者,很資深的專家就不要來(lái)說這是什么民科帖了,給初學(xué)者一點(diǎn)空間!做材料的,對(duì)統(tǒng)計(jì)物理理解的比較膚淺。 PS 發(fā)文章時(shí),計(jì)算出來(lái)的一些參量畫成圖了,這些參量還要用表格的形式精確列出來(lái)嗎? ![]() 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.(全是構(gòu)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(就是系統(tǒng)熵?) and that of the equivalent ideal gas, is a measure of the number of accessible configurations of the system .可以有偶分布函數(shù)計(jì)算出,只是由構(gòu)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振動(dòng)自旋?應(yīng)該屬于構(gòu)型? Sconf = kB lnΩ [ Last edited by parklyn on 2010-9-1 at 11:44 ] |
