Distribution of water in the Earth’s interiors and the effect of water for phase transition boundaries were clarified, and the water content in the Earth’s interior s was estimated by combining with the seismic data. Moreover, the studies for the dehydration reaction and the equation of state of the slab constituent minerals, and also the study for the effect of water to the mantle mineralogy were carried out. In addition, the study of the compositional dependence for the water content in mantle minerals was carried out. We also tried to determine the water content of magma as a function of pressure and temperature.

阐明了地球内部水的分布以及水对相变边界的影响，并结合地震数据估算了地球内部的含水量，并进行了脱水反应和状态方程的研究。此外，我们还尝试了地幔矿物成分的组成依赖性研究。确定岩浆的含水量作为压力和温度的函数。
