环境磁学磁性参数简介

Brief Introduction of Magnetic Parameter to Environmental Magnetism

环境磁学是一门能为全球环境变化、气候过程和人类活动对环境的影响等研究提供有价值的资料的边缘新兴学科。目前比较常用的磁学参数有磁化率、频率磁化率、天然剩磁、饱和等温剩磁、剩磁矫顽力、非磁滞剩磁等等,它们用途广泛,其测量既简便又快速,可为重建古环境、恢复古气候提供可靠的依据。

Environmental Magnetism is a new subject that studying the effect to the environment of global environmental changes, climatic course and mans activity and providing valuable data. Magnetic susceptibility, frequency-dependent susceptibility, natural remanent magnetizatism, saturation isothermal remanent magnetizatism, remanent coercivity, anhysteretic remanent magnetizatism et al. are the commonly used magnetic parameters at present that widely used, easily and quickly to use and they can be dependable evidences for reconstructing the palaeoenvironment and paleoelimate.
