摘　　要：将冰粉与石英砂均匀混合,在一定条件下形成天然气水合物。实验研究表明冰成天然气水合物没有诱导区,开始就进入水合物的成长区。从气-固反应动力学出发,研究了冰成水合物形成机理:冰成天然气水合物过程是冰晶分子对气体分子的吸附、催化和络合相互作用的过程。Natural gas hydrates were formed within a certain condition through symmetrical admixture of ice powder and quartz. The mechanisms of natural gas hydrates from ice were investigated and the process of ice-form was the process in which ice molecule adsorbed, congregated and catalyzed gas molecule from process of gas-solid and action of molecule. It has been proved by the data results of experiments that there was no induction time for the ice-form natural gas hydrates, but growth process of hydrate from the beginning of experiments.
