【摘要】 本文提出了一种仅用一个组分在不同温度下的无限稀释活度系数,采用非线性回归确定Wilson参数的新方法。用新方法确定了3S组二元体系的Wilson参数值。用此参数计算的活度系数与根据汽液平衡实验获得的结果符合很好。更多还原

【Abstract】 The author developes a new method for determination of Wilson parameters with the non-linear regression which needs the infinite dilution activity coefficients of only one component at different temperatures in the system, and the Wilson parameters of 38 binary systems are determined by the method, The ctivity coefficients calculated by the Wilson parameters are in a good agreement with that obtained from the VLE experiments.更多还原
