CO2 Hydrate Film is formed at the interface between liquid CO_2 and water, which is observed in ocean sequestration. It possesses a porus structure that water and CO_2 molecules are transported through the film to keep the thickness constant. The present research has been made for the followings.(1) MRI Measurement of hydrate growth has been made. The growth rate of hydrate film thickness has been measured by an specially designed high-pressure apparatus. Application to advanced CO_2 sequestration technology has also been proposed.(2) Measurement of CO_2 hydrate film thickness based on mass transport mechanism has been made by an high pressure apparatus. It was estimated to be 0.0004mm.(3) Massive CO_2 clathrate hydrate growth at a High-Polar-Energy Surface has been clarified and also, lateral growth rates of CO_2 clathrate-hydrate Film has been measured.(4) A New Boundary Condition of Lattice Boltzmann Method has been developed for the calculation of complex flow in porus media.

海洋封存中发现的CO_2水合物膜是在液态CO_2与水的界面处形成的。它具有多孔结构，水和CO_2分子通过膜传输，以保持厚度恒定。本研究主要针对以下几个方面进行了研究。(1)对水合物生长过程进行了MRI测量。用专门设计的高压装置测量了水合物膜厚的增长速率。并对先进的CO_2封存技术的应用提出了建议。(2)利用高压实验装置，根据传质机理，对CO_2水合物膜厚度进行了测量。估计为0.0004 mm。(3)本文阐明了CO_2笼形水合物在高极性能表面上的大量生长，并测量了CO_2笼形水合物膜的横向生长速率。(4)本文提出了一种新的格子Boltzmann方法边界条件，用于多孔介质中复杂流动的计算。
