摘　　要：在总结近几年夏县台井溶解气体观测工作的基础上，发现该井溶解气体中Ｈｅ的升高异常与华北北部５级以上地震有很好的对应关系，剖析了该井溶解Ｏ２和ＣＯ２含量因受生物化学反应控制而表现出相反年变形态的原因，指出该台气体观测上的问题。Based on the summarisation for the dissolved gas observation work at Xiaxian station in the past few years,it was discovered that there is good corresponding relation between the dissolved gas in the well and the M >5 0 earthquakes in the north of North China.The paper analyzed the reason that the content of the dissolved gas and the carbon dioxide in the well showed opposite annual variation shape,suggested some problems in observation,put forward a tentative idea of improving observation method,establishing comprehensive observation system and making Large scale observation.
