摘　　要：在物理化学气体部分的教学内容中,气体的压缩因子和逸度因子均为重要概念,同时也是生产、科研和设计中的重要气体基础数据。本文通过对542种无机、有机气体的临界压缩因子数据进行整理及分析,对其数值取值范围及特点进行了讨论,同时对纯气体的压缩因子和逸度因子数值的一些简单规律进行了总结,为缺乏数据时二者的估算提供依据,以供教学参考。The gas compressibility factor and the fugacity coefficient are two important concepts of real gas in the teaching of physical chemistry,and they are also important fundamental gas data for the chemical processing, study or design procedure. In this article,first,the data of critical compressibility factor for 542 kinds of inorganic and organic gases were collected and analyzed,the value range of the data of critical compressibility factor was discussed,and the values were found to satisfy the form of normal distribution,the value range with maximum distribution is about 0. 26 ～ 0. 27. Some characteristics about the compressibility factor and fugacity coefficient values for pure real gases were also concluded for different temperature ranges. We hope our work would help the teaching process of relative parts more systematically,and we also hope to provide some bases for the estimation of the compressibility factor and fugacity coefficient when the relative data are lack.
