摘要
从定襄泉水点的水文地质条件、水氡异常特点、水氡变化的正常环境影响因素等方面对1996年出现的异常可靠性进行了论证.认为异常除与气温和降水的影响有关外,还与岩石的应力—应变变化有关,是1998年张北6.2级地震比较可信的前兆异常.
The reliability of anomaly of waterradon in Dingxiang spring observation in 1996 is discussed,based on data of the hydrogeologic condition at the spring,the characteristics of waterradon anomaly and the normal influence fectors from environment.It is considered that the anomaly of waterradon not only correlates with air temperature and waterfall,but also with variation of stressstrain in rock,is the reliable precursor anomaly before Zhangbei M6.2 earthquake in 1998.
