| 摘 要： | 利用ＦＲＫＳ立方状态方程和改进的ＬＬ混合规则,拟合二元系超额体系的实验数据,得到二元参数。在不引入任何多元参数的情况下,直接用二元参数预测四元系的超额体积。对四元系的计算结果表明,该方法能给出较好的预测结果。

| Abstract: | The FRKS equation of state and the improved LL mixing rule were used to correlate excess volumes of binary mixture to gain binary parameters.The quaternary excess volumes were predicted by using only binary parameter without any multicomponent parameters.The results obtained for quaternary mixture are in good agreement with experimental data. |

| Keywords: | excess volumes equation of state binary quaternary correlation prediction |
