摘　　要：提供一个基于分子聚集理论计算压缩液体比容(密度)的新方法。另外还对摩尔组成为正丁烷40.59%、水59.49%的双元混合物压缩液体体积性质在较宽密度范围内进行研究和计算,而所得计算结果与实验数据符合良好,这表明,本方法是适合用来计算压缩液体混合物的p-V-T性质。A new method for estimating the compressed liquid specific volumes （densities） based on the theory of molecular aggregation was proposed. In addition, the compressed liquid volumes of the n-butane （A） and water （B） binary mixture with the A/B molar ratio of 40.59：59.49 were investigated. The calculated results of the compressed liquid volumes over a wide density range by the proposed method were in agreement with the experimental data. It showed that the proposed method is suitable to calculate the p- V-T properties of the compressed liquid mixtures.
