摘要: Abstract Layers of methane-saturated amorphous ice were obtained by deposition molecular beams water and gas on a substrate cooled with liquid nitrogen. Their heating is accompanied glass transition (softening) subsequent spontaneous crystallization. The avalanche-type initiation crystallization centers captures the molecules does not lead to their displacement motion front. Under water–gas condensates in conditions deep metastability formation hydrates takes place. Glass-transition temperatures determined changes dielectric properties under heating. method differential thermal analysis has been used investigate kinetics layers. Properties that characterize have basis data dependence temperature rate.
