Ar-N_2混合气体输运性质的量子力学研究

A QUANTUM MECHANICAL ANALYSIS OF THE TRANSPORT COEFFICIENTS FOR Ar IN N 2 GAS

基于物理力学理论，利用量子力学的ＩＯＳＡ方法、Ｎｕｍｅｒｏｖ相移计算法和ＡｒＮ２相互作用的等效势模型计算了Ａｒ在Ｎ２气体中的扩散系数的粘滞系数，计算值与实验值符合较好，比Ｇｉａｎｔｕｒｃｏ等人（ＧＶＤ）计算便更接近实验值，特别是粘滞系数，在整个计算区域内基本和实验相同。

The diffusion coefficients and interaction viscosities for Ar in N 2 are calculated based on physical dynamics theory,by employing quantum mechanical IOSA approximation and Ar N 2 effective interaction potential.The calculation results are in good agreement with the experimental values,and better than those of Gianturco and others.The calculation interaction viscosity values are very close to experimental ones in the caluculation range.
