摘要
本文应用 Tang—Toennies 势模型计算了 H—H_2相互作用势,并在此基础上用物理力学方法计算了氢原子在氢分子中的扩散系数和粘滞系数.所得结果与实验值极其它理论相比较,更接近于实验值。最后从原子与分子物理学的观点出发,对其结果提出理论解释.
The authors calculate the interation potential between hydrogen atom and hydrogen by employing Tang-Toennies model.On the basis of this we calculate the diffusion coefficient and viscosity of binary mixture.Our results are comp- arable to the best experimental data.From the.point view of atomic and mol- ecular physics,we point out the different transport properties of binary mixt- ure are related to the different parts of the interaction potential of correspon- ding system.
