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。
The relationship between the δHe / Ar values and the several earthquakes in the fault gas in the Tachen area from the end of June 1990 to December 1991 is discussed. Seen from a few earthquakes that have been obtained, some earthquakes δHe / Ar appear negative anomalies, while others are positive anomalies. The δHe / Ar value has a good ability to reflect the earthquake.
