摘　　要：介绍了液-液分界面气体水合物的生成机理和球形生长模型,为了简化模型,从传热学角度作了假设,认为沿着模型半径方向是一维传热。对数学模型进行了理论推导,计算了在不同水温下生成定量水合物所需的时间,得出相应的理论曲线,分析得到水合物生成的最优温度,从节能和优化的角度对快速制备水合物提供了理论依据。The formation mechanism of gas hydrate at liquid-liquid interface and the spherical growth model are introduced. In order to simplify the model, it is assumed from the point of heat transfer that the model is one-dimensional heat transfer along the radius direction. The mathematic model is de- rived theoretically, the time required to generate quantitative hydrate at different temperatures is calculated, and the corresponding theoretical curve and the optimal temperature for generating hydrate are obtained, which provides a theoretical basis for rapid preparation of hydrate from the point of energy saving and optimization.
