摘　　要：在对不同气体水合物驱动力表达式进行归纳与总结的基础上,重点分析了它们的区别与联系,提出了描述气体水合物结晶驱动力的一般概念,并着重强调在对水合物反应动力学研究的过程中,应区分影响水合物形成的关键因素,从使用不同驱动力表达式入手,通过试验数据对水合物反应动力学模型中的相关参数加以分析改进,以期对不同条件下气体水合物的结晶动力学进行合理有效的分析求解。Difference and similarity of various ex- pressiones for driving force of gas hydrate were ana- lyzed especially on the basis of definition conclusion in this paper.General conception to describe the driving force of gas hydrate was proposed.It is pointed out that the key influential factor which affects gas hydrate for- mation must be distinguished in the process of applica- tion.That is to say,reaction dynamics mode of gas hy- drate should be developed according to different ex- pression of driving force in order to obtain efficient a- nalysis of gas hydrate nucleation dynamics.
