The effect of hydrostatic pressure on the formation of air-hydrate crystals
The transformation of air-hydrate crystals from air-bubbles in ice was observed by a microscope at 270K under high hydrostatic pressure between 19.6 and 34.3MPa during the period of 16 days. The number concentration of the air-hydrates formed by the pressurization was measured and was compared with...
