摘要
本文简述了测定水中离子的一种先进技术——离子色谱法的基本原理,作者用离子色谱法测定延庆五里营井的资料表明,SO_4^(2^-)、Cl^-、F^-离子是该井反映地震活动比较灵敏的组分,其含量在延庆四海3.0级地震和宣化张家湾M_s4.2级地震前后都发生了明显的负异常变化。
This paper briefly describs the basic principle of an advanced technique for determining ions in water-- the ionic chromatography The data that authors hereobtained in Wuliymg well using ionic chromatography show that ions of SO42-, Cl-and F- are relatively sensitive components in reflecting seismic activity in this well, and their contents appeared clearly negative anomaly variation around the Sihai earthquake with M = 3.0 in Yanqing and Zhangjiawan earthquake of MS = 4.2 in Xuan-hua
