Based on the noble gas atom interaction potentials by means of Tang Tiennies potential model, the author calculates the macroscopic properties for pure Helium and its mixtures, including second virial coefficient B,viscosity η,thermal conductivity λ,diffusion coefficient D,and thermal diffusion factorα T. Finally,the author compare her results with the best ones given by J.Kestin et al and get a good agreement. However, our method is theoretical and the potential function used has good analyticity. Therefore, it is easy to apply.
