英文摘要: Abstract(#br)To investigate the influence of foreign gas inclusion on the crystallization of ice, we studied the low-temperature (74 < T < 160 K) vacuum deposition of water molecules mixed with Kr or CH 4 in a wide range of H 2 O/gas mixing ratios (0.004 < R < 4) by means of in-situ X-ray diffraction. When H 2 O vapor containing either Kr or CH 4 was condensed onto a cold substrate, ice Ih crystals were found to grow below 130 K in a film of amorphous solid water (ASW), whereas pure H 2 O gas formed only ASW below 135 K. Small to moderate concentrations ( R > 0.2) of Kr and CH 4 enhance the formation of ice Ih and increase the crystal size, while at high foreign gas contents ( R ⩽ 0.2) that may develop Kr or CH 4 crystals below 92 K, the crystal size and relative amount of ice decrease...
