摘要
本文根据Dimer与Trimer的特性,提出一个非理想量子气体的模型,并求得玻色子系统三阶维里系数的近似表达式。对~4He系统进行了具体计算,结果与实验值相符。
In accordance to the characteristics of Dimer and Trimer, this paper presents a model of non—ideal quantum gas and derives the approximate expxession of the third virial coefficients for Bose system The results obtained for the ~4He system consist with the experiment.
