Ar-O_2混合气体输运性质的量子力学研究

QUANTUM MECHANICAL ANALYSIS OF TRANSPORT COEFFICIENTS FOR Ar IN O_2 GAS

基于物理力学理论，利用量子力学的IOSA方法和Ar－O2等效势模型计算了Ar在O2气体中的扩散系数和粘滞系数，计算值与实验值符合较好，比经典计算值更接近实验值，谈．明我们的方法是有效的，所用的Ar－O2相互作用等效势模型反映了该系统相互作用的客观情况。

Diffusion coefficient and interaction viscosity for Ar in O2 are calculated based on physical mechanical theory, by employing quantum mechanical IOSA approximation and Ar-O2 effective interaction potential. The calculation results are in good agreement with the experimental values, and better than the classical calculation data. It shows that the method is effective. The potential model indicates the information of Ar-O2 interaction correctly.
