| 摘 要： | 考虑到水合物的结构具有明显的络合物特性，提出水合物的生成过程首先是一个络合反应过程，其次才是溶解过程。在络合过程中，气体分子和水分子按最稳定的方式构造多面体，这些多面体通过氢键连接形成水合物；在连接过程中，会形成另一种多面体状孔穴。如果气体分子的尺寸足够小，就可进一步溶解在这些孔中，并会起到稳定水合物的作用。根据这一设想所建立的数学模型能很好地用于计算水合物的生成压力，得到合理的孔穴占有状况，说明本理论能更好地描述水合物的生成机理。

| Abstract: | Instead of taking the clathrate hydrates as one sort of solid solutions andassuming that the process of gases encapsulation in the hydrate cavities was similar toLangmuir adsorption. the paper suggestes that the gases encapsulation include two process.Thefirst one was complex reaction.and the second one was adsorption.In the first process,thebasic structure of hydrate was formed.As there are empty cavities left in the basic structrue,gases can be subsequently solved in it and make it more stable and non-stoichiometric.Basedon this physical model,one mathematical model for the calculation of hydrate vapor pressureswas proposed. The good results were obtained. |
