用可探测土壤内部水含量变化的p-|meter探头开展了甲烷水合物形成与分解过程中多孔介质内部水含量变化研究，结果表明，该新型研究方法可有效探测实验过程中多孔介质内水含量变化。通过研究指出：水合物生成时会对介质内的水产生吸力，将水向水合物处抽吸；水合物分解时会释放水，使介质内水含量增大；温度升高会使存于多孔介质内毛细管中的水向下流动；水合物在粉土中的二次形成范围比一次形成范围更大。

Water changes inside loess during the formation and dissociation processes of methane hydrate were studied with a pF-meter sensor which could detect water changes inside soil. It was proved that the new research method with pF-meter sensor could instantly detect the water changes inside loess in the experiment, effectively. It was experimentally shown that hydrate formation could cause a kind of suction which could pump the water inside loess toward hydrate and the water release from hydrate dissociation could increase water content of loess and the water existing in the capillaries of loess could flow down following temperature rise. Additionally, the scope of secondary methane hydrate formation in loess was larger than that of the initial hydrate formation.
