本文根据分子结构的特点，借助图论探讨了正烯烃的沸点与分子结构的关系，提出了一个具有一定结构基础的定量关系。对４０种正烯烃的计算结果表明，沸点计算值都接近实验值，平均误差仅０．０５４％。
According to the characteristics of molecular structure, this paper discusses the relationship between the boiling point of n-alkene and the molecular structure by means of graph theory and proposes a quantitative relationship with a certain structural basis. The calculation results of 40 n-olefins showed that the calculated boiling points are close to the experimental values, with an average error of only 0.054%.
