摘要： 提出了描述相际分子转移行为的双阻力物理模型,并给出每项阻力的计算方法;导出一相中的分子向另一相转移的质量通量的计算公式;提出了相平衡的质量通量准则以代替化学位准则,并因此得到两相平衡时的密度关系方程;该方程用于预测液体的蒸气压并取得较好的结果。

Abstract: A physical model, named "double -resistance model", was proposed to describe the transfer of molecules between two adjacent phases. Based on this model, the equation for the calculation of mass flux was derived. Instead of chemical potential criterion, mass flux criterion was suggested and the relationship of the densities of two phases was obtained when they were in equilibrium. This relationship was used to predict the vapor pressure of pure liquids and good results were obtained.
