将统计热力学模型与作者建立的传热反应速率理论相结合，通过液体混合物中分子间的相互作用能、分子的大小和形状，将液体混合物的导热系数与汽液平衡相互联系起来，使这两类液体混合物的性质统一到分子间相互作用能、分子的大小和形状这一液体混合物的共性上，对这两类性质进行统一的描述，研究这两类性质之间的关系。对１１对二元体系根据液体混合物的导热系数对汽液平衡进行了推算。结果表明，所建立的液体混合物的模型能够描述它们的导热系数与汽液平衡之间的相互关系。
Combining the statistical thermodynamic model with the heat transfer reaction rate theory established by the authors, the thermal conductivity of the liquid mixture is correlated with the vapor-liquid equilibrium through the intermolecular interaction energy, molecular size and shape of the liquid mixture, The properties of the liquid mixture are unified to the commonality of the liquid mixture of the molecular interaction energy, the size and the shape of the molecule. The two types of properties are described uniformly and the relationship between these two properties is studied. For 11 pairs of binary systems, the vapor-liquid equilibrium is estimated based on the thermal conductivity of the liquid mixture. The results show that the model of the established liquid mixture can describe the correlation between their thermal conductivity and vapor-liquid equilibrium.
