摘要
通过对甘肃及周围地区近几年来发生的６级以上地震前后水氡异常特征和时空演变分析，提出了西北地区水氡震后调整性异常与新地震异常之间的区别及三项判别指标。
By analyzing the anomaly characters of radon before and after earthquakes (M S≥6.0) in Gansu Province and around it and their space time evolution,the distinguishing and judging indices of radon anomalies before and after an earthquake.This is very important to earthquake prediction.
