| 摘 要： | 本文利用经典热力学理论，以分子取向次序的“焓—熵互补性”经验认识为基础，推导出一个新的计算过量热容的数学模型，并用十五个似球型分子—正烷烃二元物系的热力学数据对此模型进行检验；同时与Ｆｌｏｒｙ理论、Ｅ．Ｌｉｅｂｅｒｍａｎｎ模型进行比较．结果发现，本文模型能够很好地预测过量热容，并且优于上述二种模型。

| Abstract: | On the basis of experimental knowledge of Enthalpy-Entropy com-pensation for correlation of molecular order(CMO),a mathematical model for predicting excess heat capacities has been derived from classical thermodynamics theory.The model has been tested by data of about l5 binary systems con taining appoximately spherical molecules-normal alkane molecules,and also has been compared with Flory theory and E.Liebermann model.It is shown that the new model can predict very well and is better than the other two models |
