摘要: 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。

关键词: 粘滞系数, 扩散系数, Ar-N2等效势模型, Numerov相移计算法

Abstract: The diffusion coefficients and interaction viscosities for Ar in N2 are calculated based on physical dynamics theory, by employing quantum mechanical IOSA approximation and Ar-N2 effective interaction potential. The calculation results are in good agreement with the experimental values, and better than those of Gianturco and others. T he calculation interaction viscosity values are very close to experimental ones in the caluculation range.

Key words: diffusion coefficient, interaction viscosity, Ar-N2 interaction potential, Numerov method
