摘要：

A unique apparatus for measuring the dendritic growth velocity of ice crystals in undercooled water is described and a preliminary result at undercooling levels between 5 and 8.5 K is presented. The result appears to show a significant deviation from the theoretical prediction based on the thermal diffusion model possibly due to sluggish interface kinetics which start playing a role in dendritic growth at these undercooling levels. Discussion includes necessary modifications of the diagnostic technique in order to eliminate uncertainties in the preliminary data and improve the accuracy in future measurements.
