摘要：

Thermal diffusion factors, alpha-T, are reported for the systems He-nC3H8, He-C4F8, and CH4-C4F8 at 300 K as functions of concentration and pressure; excess second virial coefficients are also reported for each system. The alpha-T values are extrapolated to zero pressure and the theory of Oost, Los, Cauwenbergh, and van Dael is used to predict the pressure dependence of alpha-T at each concentration for comparison with the experimental results. The data for CH4-C4F8 do not agree with the theory.
