| 摘 要： | 从定襄泉水点的水地质条件、水氡异常特点、水氡变化的正帘环境影响因太等方面对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，还与岩石的应力一应变变化有关，是1998年张北6．2级地震虑较可信的前兆异常。

| Abstract: | The reliability of anomaly of water-radon in Dingxiang spring observation in 1996 is discussed, based on data of the hydrogeologic condition at the spring, the characteristics of water-radon anomaly and the normal influence fectors from environment. It is considered that the anomaly of water-radon not only correlates with air temperature and waterfall, but also with variation of stress-strain in rock, is the reliable precursor anomaly before Zhangbei M 6.2 earthquake in 1998. |
