摘　　要：3He作为一种特殊的工质在低温工程、基础物理学和空间技术等领域获得重要应用,这些应用需要可靠的3He热力学性质数据。但是目前没有适用于3He的宽范围状态方程。不仅如此,而且有关的热物性实验数据也十分稀缺,这给应用3He的研究人员带来了困难。本文基于全面收集和整理有关3He的各类数据,通过编写计算机程序,考察了五种常用的状态方程(理想气体状态方程,范德瓦尔方程,RK方程,RKS方程和PR方程)用于计算3He在4K^100K温区定压下比容-温度关系的可行性,并将计算结果与实验数据进行了比较。这些比较结果将为3He状态方程的研究提供有价值的参考。^3He,as a special substance, is now having more and more applications in the field of cryogenic engineering, fundamental physics and space technology, etc. These applications need reliable thermodynamic data of ^3He. However, there are not any state equations in wide range for ^3He so far. In addition, its thermodynamic data are extremely shortage, which brings inconvenience for researchers on ^3He. On the base of collecting and picking up different kinds of data of ^3He, as well as writing down computer programs, this paper checks the feasibility of V-T relatlonship using five normal state equations from 4K -100K, and compares the calculational data with the experimental data, which make valuable reference for the research of the state equation of ^3He.
