| Research Abstract |
Developed in this work is an experimental device for the measurement of the thermophoretic velocity under high temperature gradients by means of utilizing a micro-gravity environment during a free fall. Experiments are conducted repeatedly so that enough amounts of data are accumulated for statistical treatment, which is confirmed to enable notable improvement, in comparison with existing experiments, in the measurement accuracy. An improvement in the theory is also achieved ; the prediction by the new theory coincides satisfactorily with experimental results.
