摘要: 论述了1990年6月底至1991年12月期间塔院断层气体中δHe/Ar值变化与几次地震的关系。从已获得的几次震例来看,有的地震δHe/Ar出现负异常,而有的出现正异常。δHe/Ar值具有较好的映震能力。Abstract: This paper discusses the relation detween δHe/Ar ratio variation of Tayuan fault gas and several earthuakes from June/1990 to December 1991.From several obtained earthquake examples, it can be seen that,for some earthquakes,the δHe/Ar ratio shows a negative anomaly,but for other earthquakes, showing a positive anomaly.The δHe/Ar ratio has a better capability to reflect earthquakes.
