| 摘 要： | 提出了估算沸点下蒸发焓的含基团重量分率的基团法和估算式，拟合团贡献值，对３８５种有机物的计算平均偏差约为１．５％。所提出的新方法明显优于３种对应状态和用蒸发熵的基团法。

| Abstract: | The expression of estimating enthalpies of vaporization at boiling point has been proposed by the functional group method containing group weight fraction. The numerical values of the functional groups are fitted with the experimental data of 385 organic compounds. The average deviation of estimation is about 1.5%. The new method is superior in many respects to the three corresponding state methods and the functional group method for the evaporation entropy. |
