It was shown that at atmospheric or subatmospheric pressure, fugacity coefficient of vapor phase for components of these systems deviates seriously from unity. 示出了在常压或低压条件下,这些体系组分的汽相逸度系数对1的较大偏离。
A Brief Analysis of Relation between Fugacity Coefficient and Pressure 浅析逸度系数随压力变化的关系
The fugacity coefficient of the vapor phase for the components of these systems deviates seriously from unity owing to association. 在低压下,含羧酸体系的汽相由于缔合从而引起组分的汽相逸度系数偏离1较大,故对汽相非理想性的校正是不容忽视的。
After the modification with fugacity coefficient and crystallinity, the deviation is reduced. 通过加入逸度系数、结晶度的修正,模拟与实验结果之间的偏差有所减小。
