| 摘 要： | 叙述了1989年大同6.1级地震前，山西夏县台井溶解气组分He、CO2出现的异常变化，对热水区内各井孔气体成分含量进行了对比研究得出，小近震所产生的He、O2的突跳，是由于热水体受应力作用，地下热水晕的中心和边界发生改变，使不同含量的热水发生混合所致的结论。

| Abstract: | Discussed in this paper is the abnormal variation of the dissolved vapour in Xiax-ian Well in two groups, (He and CO2) before the Ms 6.1 earthquake in Datong in1989. Comparations are made to study the contents of each hole of the wells withinthe thermal water area and a conclusion is drawn that the springs of He and CO2 produced by the small and near earthquakes are because that the thermal water is affected by stress and that there occur changes both in the center and at the edge of underground thermal water halo, which cause thermal water of different contents of Heand CO2. |
