摘　　要：利用现有文献中数据计算出H2与稀有气体原子间的Born-Mayer系数,然后在求得的Born-Mayer系数基础上,通过Tang-Toennies势(简写为TT势)模型理论计算了H2与稀有气体原子间的相互作用势,得到了较好的势能曲线;同时在此基础上,基于Chapman-Enskog方法,计算出了H2与稀有气体原子间的扩散系数与热传导系数,最后将计算结果与Tayebeh Hosseinnejad,Hassan Behnejad等人的计算结果进行了比较,两者的计算结果极为接近.Firstly,the authors calculated the Born-Mayer parameter of H2 with inert gas atoms with the data in the literature referred in this paper.Then on the base of Born-Mayer coefficients,the authors calculated the interaction potential between H2 and inert gases in the Tang-Toennies potential（TT potential for short） model and got excellent curves of the potential.At the same time,the diffusion coefficient and thermal conductivity of the systems were further concerned.The results were compared with Tayebeh Hosseinnejad and Hassan Behnejad＇s,and a good agreement was got.
