摘　　要：叙述了大同市镇川堡处于口泉大断裂上的２口相距２ｍ的一组观测井在大同－阳高２次中强地震前的不同异常表现形态，探讨了产生异常差异的原因，指出这些差异似与观测井所处构造部位、地震类型、震源深度、观测条件等有关。The different anomalous shapes of the 2 wells before the 2 medium strong earthquakes at DatongYanggao that the distance between the 2 wells is 2m and locate at Kouquan fracture in Zhenchuanbao of Datong had been recounted, the reason of the anomalous difference had been discussed. It was pointed out that the anomalous difference relates to the tectonic positions of the observation wells, the type of earthquake, the depth of focus and the observation conditions.
