对二氧化碳与氩气、氪气和氙气混合物的热扩散系数进行了测量。首先，热扩散系数通过一个正的最小值，这证实了Waldmann通过对扩散热效应的研究得出的结论，即在400-200°K范围内，热扩散系数随温度的降低而增大。对于其他混合物，随着温度的降低，热扩散系数变为负值，并且在可达到的温度范围内没有最小值的迹象。
Measurements are reported of the thermal diffusion factor for mixtures of carbon dioxide with argon, with krypton, and with xenon. For the first, the thermal diffusion factor passes through a positive minimum value, and Waldmann's conclusion, from his study of the diffusion thermo‐effect, that the thermal diffusion factor increases with decreasing temperature in the range 400–200°K is confirmed. For the other mixtures, the thermal diffusion factor becomes negative as the temperature decreases, and there is no indication of a minimum value in the accessible temperature range.
