本文通过对Van der Waals模型中排斥体积的修正, 建立了一个液体状态方程式,并将它推广到了二元液体混合物, 预测和关联了液体混合物的过量性质, 计算结果表明, 可与Flory理论相比拟, 但所需提供的纯组分性质比Flory理论少, 计算也得到了简化.

关键词: 液体, 混合物, 热力学函数, 状态方程, 范德华力

A new equation of state of liqs. is established by modifying the excluded vol. in van der Waals theory. It is extended to correlate and predict the excess properties of binary liquid mixtures The calculation shows that the results are comparable to that of the Flory theory, but the calculation is simpler and the pure-component properties needed are fewer.

Key words: LIQUID, MIXTURES, THERMODYNAMIC FUNCTION, EQUATIONS OF STATES, VAN DER WAALS' FORCES
