| 摘 要： | 地球内部水的分布与循环对了解地球内部的物理化学性质、地球动力学和地球的演化起着重要的作用.本文综述了地球内部水含量的探索方法、存在状态、地球各个层圈水的储存能力、高温高压下矿物中的溶解度以及地球物理观测(大地电磁和地震波)结果等方面的研究进展.研究结果表明,地球内部储存的水可能超过了地球表面大洋水的数倍.微量的水能够引起地震波速度的降低和电导率的显著增加.

| Abstract: | Distributions and circulars of water play an important role in understanding the physical and chemical properties of earth interior, geodynamical process, and evolution of earth. This paper reviews the various aspects of water in the earth's interior,including the exploring method, state, storage capacity, content in the different spheres of earth, solubility in minerals at high temperature and pressure, and some results from geophysical observations. The amount of water content in the earth s interior may be several times larger than that at the earth's surface. Trace water can significantly affect the electrical conductivity and velocity of seismic wave. |

| Keywords: | nominally anhydrous minerals (NMS) hydrous phase water solubility electrical conductivity velocity of seismic wave |
