摘　　要：根据Flory溶液理论,导出计算溶质偏摩尔体积的方程。作者还提出了确定方程参数的新方法,用这种方法只需纯水的物性数据就能计算有机溶质在水中的无限稀偏摩尔体积。对25类同系列物质共167种有机溶质298.15K下的计算结果和实验值符合十分良好。An equation for calculation of the partial molar volumes for organic solutes has been derived from the Flory theory, and a new method to determine the parameters in the equation has been developed. As a result, the infinite dilute partial molar volumes for the organic solutes, which include 25 homologues consisting of 167 substances, were calculated from the properties of pure water only. The calculated results are in good agreement with the experimental data.
