| 摘 要： | 本文测定了苯—正壬烷、苯—正十一烷、环已烷—正壬烷、环已烷—正十一烷、四氯化碳—正辛烷五个二元物系过量热容Ｃ，并与Ｆｌｏｒｙ理论对Ｃ的预测值进行了比较，得到了分子取向次序变化对Ｃ的贡献大小。结果发现Ｆｌｏｒｙ理论对Ｃ的预测值与Ｃ的实验值偏差很大，分子取向次序的破坏对Ｃ的贡献为负值。

| Abstract: | In this paper,excess heat capacities C for five binary systems ofn-C9,-n-C1l,C-C6-n-C9,-n-C11,CC14-n-C8 have been determined andcompared with the C values predicted by using Flory theory. The order contribution toexcess heat capacities has been valued.It is concluded that the deviations of C (Flory)from C (exp) are very large,and the order destruction causes a negative contribution toexcess heat capacities. |
