摘要
本文应用前文的α端值法导得:在低压下二元非理想溶液的恒压汽液平衡组成方程,其中活度系数为液相组成 x 的函数。实例计算表明:α端值法与泡点法计算结果相差甚微,两者对应点 y 值之差|Δy|<10^(-3)。
The gas-liquid equilibrium component equation of two-element practical solution under constant pressure is derived from the terminal value alpha dealt with in an earlier paper.The activity coefficient in the equation is a function of the liquid phase component x.Calculated results of practical examples show that the difference between the results calculated by terminal value alpha and those by effervescence point is only |Δy|<10^(-3) for a point.
