摘要
在介绍冰芯固体直流导电特性检测（ＥＣＭ）技术方法和检测原理的基础上，论述了ＥＣＭ检测技术应用于冰芯研究领域所具有的非破坏性、快速性和高分辨率的特点，分析阐明ＥＣＭ数据在冰芯年代划分、恢复火山活动历史、确定参考层位和生物质燃烧事件等方面的应用价值和研究意义。
Current emphasis upon the high resolution profiles established from ice cores has drawn attention to electrical conductivity measurement(ECM) in ice core studies.In this paper,we describle the technological methods of ECM system and analyse the advantages of ECM on rapid measurement,high spatial resolution and little wreckage.And the applications and progresses of ECM data in ice cores are classified.In addition,particular effort has been made in clarification of the environmental record significance of ECM data to improve a better undersanding of ECM data in ice core studies.
