摘要：

Thermal diffusion was measured by a flow technique for the system CHBr2 center dot CHBr2 - CHCl2 center dot CHCl2, with both normal ( top hot) and inverse ( top cold) temperature gradients. In contradiction to the literature a positive Soret coefficient was observed. It was also found that the concentration gradient due to thermal diffusion (top hot) was destroyed when the temperature gradient was inverted. This important observation is in agreement with experiments on this system in a Benard cell (preceding letter).
