| 摘 要： | 1996年 3月至 1998年 8月 ,新疆伽师地区发生了 11次 6 .0级～ 6 .9级地震的强震群 ,震前 ,北天山地区 5个水化学观测点出现了不同程度的水化学强震远场效应 ,认为硫化物、CO2 的生成 ,或 He,F-的存在 ,明显受区域应力场的影响 ,再加上各观测水点 (泉 )独特的地下水成因类型 ,是造成硫化物、CO2 ,He,F-等各水化学项目形成强震远场效应的重要原因。

| Abstract: | From March 1996 to August 1998,a swmarm with 11 times more than 6 0 strong earthquakes occurred in Jiashi,Xinjiang Prior to these earthquakes, five hydrochemical observation points in North Tianshan Mountian region appeared different hydrochemical far field effect The course of sulfide and cabon dioxide forming and existence of helium ion and fluorine ion came under the influence of regional stress field, and the special origin of groundwater at every observation leaded to far field effect of each hydrochemical item |
