摘要：
The dynamic process and kinetics of gas hydrate formation and dissociation have been studied by means of Raman spectroscopy. The formation and dissociation of methane and carbon dioxide hydrates as well as the phenomenon of interchange of the components were observed as functions of time, temperature and pressure conditions. From the direct observation, it was found that the reformation of carbon dioxide hydrate occurred at the surface and inside the sample of methane hydrate as well as producing ice crystals.
