On the Growth of Ice-Crystals in the Air

[摘要]  The processes of the ice-crystal formation on nuclei have been studied experimentally. Replicas of ice-crystals formed by seedings of AgNO3 MgO, AgI, etc. were examined under optical and electron microscopes. The mode of the growth of ice-crystal by sublimation depends not only on temperature and water vapour excess, but also on condition of diffusion field of water vapor surrounding the crystal and impurities in air. The mode of ice-crystal growth is briefly discussed.
