 note = {P(論文), Single ice crystals have been grown in air at various constant pressures at -30℃ and various constant supersaturations, and measurements of normal growth rate and in situ observations of the surface micromorphology of ice crystals have been made. As a result, it has been found that the habit and the morphological instability of ice crystals grown at -30℃ vary markedly not only with supersaturation and crystal size but also with air pressure. On the basis of this study, it is considered that many snow crystals formed in polar regions at a supersaturation below about 2% grow by a screw mechanism, while at a supersaturation about above 10% they grow by a nucleation mechanism.},
