In this study, I have developed techniques for precise measurements of elastic wave velocities for polycrystalline sintered bodies of high-pressure phases at pressure up to 30GPa and temperature up to 1873K, equivalent to those of the upper most lower mantle, by a combination of Kawai-type multi-anvil apparatus, ultrasonic interferometry, and synchrotron radiation.

在这项研究中，我已经开发出的技术，精确测量的弹性波速度的高压相的多晶烧结体的压力高达30 GPa和温度高达1873 K，相当于那些最上层的下地幔，由河井型多砧装置，超声波干涉仪和同步辐射的组合。
