摘　　要：论述了以仪器中子活化分析技术为检测手段的地气测量技术在双流－成都－德阳隐伏断裂带上的研究成果。地气异常主要出现在隐伏断裂的正上方，其元素组合为Ｗ、Ｓｂ、Ｌａ、Ｓｍ、Ｃｏ、Ｋ和Ｎａ等微量元素和造岩元素。The geogas prospecting technique is a new method for finding concealed deposits by means of collecting and analysing trace-elements in ascending gas from underground. The experimental results of employing this method based on INAA at the Shuangliu-Chengdu-Deyang concealed fault zone are presented. Geogas anomalies are found almost on the top of the fault and the element combination may be some trace elements and petrogenic elements, such as W, Sb, La, Sm, Co, K, Na etc.
