【 摘 要 】

References(5)Cited-By(1)A methane hydrate crystal annealed at maximum pressure remembers the compression in the hydrate S-cage until the higher equilibrium temperature for maximum pressure is reached. The hydrate S-cage-like structure in the aqueous solution also remembers the compression until the so-called activation energy is given by heating. Therefore, the hydrate crystal compressed by the maximum pressure is reformed at the equilibrium temperature for the maximum pressure.
