文摘 布里渊散射通过测定光的频移,精确计算物质的声速、弹性系数、弹光系数、折射率、绝热体弹模量,极化率,绝热方程等一系列基本的物理量。以这些物理量为基础,可以得到物质的相变、结构,以及地球深部及行星内部物质的组成、状态、性质等信息。声速和弹性对于压力的依赖性对模拟地球的成分和演化具有重要作用。本文介绍布里渊散射的产生和原理,从不同温度、压力的角度阐述了布里渊散射在地球科学中的应用,对目前该研究存在的问题作出了评述,并对布里渊散射光谱的发展趋势进行了展望。
其他语种文摘 By means of measuring the frequency shifts, a series of physical quantities can be accurately calculated by Brillouin scattering like sound velocity, elastic constants, elasto-optical coefficient, refractive index, bulk modulus, polarizability and adiabatic equation. On the basis of these quantities, we can get material's phase transitions, structures and the information of earth and planetary interior. In this article, the research progress is reviewed on the following aspects: Brillouin scattering, applications of Brillouin scattering earth science under different temperatures and pressures. At the last of this paper, the further prospect was discussed.
