Hydrogen hydrate is solid crystal which is made of water and hydrogen molecules. I performed the high-pressure experiments for hydrogen hydrate, and high-pressure structural changes and their stabilities for hydrogen hydrate were examined. In order to detect the intermolecular interactions separately from the water and hydrogen molecules, the deuterated hydrogen was used for the sample. Recently, this hydrogen hydrate has been expected to play an important role for the reservoir of the hydrogen molecules in planets, their moons and protostar. Thus, the present research is important for the modeling of the formation and evolution of these bodies.

氢水合是由水和氢分子制成的固体晶体。我对氢水合物进行了高压实验，并检查了高压结构变化及其对氢水合物的稳定性。为了从水和氢分子分开检测分子间相互作用，将氘化的氢用于样品。最近，预计这种氢水合物将对行星，卫星和原恒星中的氢分子的储层发挥重要作用。因此，本研究对于建模这些身体的形成和演变很重要。
