| 摘 要： | 本文应用TT势计算了~3He和~4He气温体在0.1K—3273K温度范围内的粘滞系数和热传导系数,以及~3He和~4He气体等摩尔二元混合在0.1—373K内的输运性质,计算结果与Kestin等人的数据符合得很好。计算中用了经典和量子力学两种输运截面公式,T=373K时两种计算得出的输运系数,其相对偏差在0.7％左右,随温度降低偏差逐渐增大。

| Abstract: | In this paper,the viscosity coefficients and the thermal conductivity coefficients of Helium-3 and Helium-4 dilute gases in the range of 0. 1K-3273K,and the transport properties of the equimolar binary mixture of Helium-3 and Helium-4 in 0.1K-373K are calculated by using TT potential. The results are in better consistence with the data given by Kestin et al. In which, both the classical formula of transport cross sections and the Quantum-mechanical ones are adopted.The relative deviations of the transport coefficients calculated by two methods are about 0.7% at 373K,and the deviations increase with temperature descending below 373K. |
