本文作者提出一种仅从一个组份在不同温度下的无限稀活度系数利用非线性回归技术确定Wilson参数的方法.并用此方法定出35个二元体系的参数.用所定出的参数计算活度系数的结果和由汽液平衡实验得到的结果符合很好.
The authors propose a method for determining Wilson parameters using only a single component of infinite dilute activity at different temperatures using the non-linear regression technique, and using this method to determine the parameters for the 35 binary systems. The results of the activity coefficient agree well with those obtained from the vapor-liquid equilibrium experiment.
