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。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.
