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.

地幔形成物质中的含水成分可以引起地震变形行为、熔融关系和波传播的较大变化。在这个项目中，我们研究了围绕氢原子的压力诱导结构响应。特别地，用振动光谱和高压中子衍射研究了水合硅酸镁和部分碳酸氢。详情请参考我们的论文原文。
