Hydrous components in mantle-forming material can induce considerable change in deformation behavior, melting relationship and wave propagation of earthquake. In this project, we have investigated pressure-induced structural responses surrounding hydrogen atoms. In paticular, hydrous magnesium silicate and some hydrogen carbonate were investigated by vibrational spectroscopy and neutron diffraction at high pressure. Please refer our original papers for the details.

地幔形成材料中的含水组件可以引起变形行为，熔融关系和地震传播的显着变化。在这个项目中，我们研究了压力诱导的氢原子周围的结构反应。在高压下的振动光谱和中子衍射中，研究了在含水镁和一些碳酸盐中的含水。请参阅我们的原始论文以获取详细信息。
