摘要: 依据郝建国等提出的异常判别规则对大气电场的原始观测资料重新进行了异常判别和分组, 并依据朱成熹等提出的效率值法,分别对监测到的异常及实际上报的异常与地震预报的相关进行了统计检验及评分,信度在 15% 以下,该方法通过了假设检验。 结果表明,这一方法用于地震预报是有统计依据的。

Abstract: In this paper, the original data of atmospheric electric field is classified according to the anomaly criteria given by Hao Jianguo and others, then the statistical test is carried out for the correlation between the earthquake events and the observed corresponding anomalies and the correlation between the predicted earthquakes and the actual events, and finally the prediction evaluation is made according to Zhu 's method. When the cred-itability is 15%, the method passes the statistical test, and it is proved that the method is reasonable for the earthquake prediction.

Key words: Atmospheric electric field, Anomaly criteria, Prediction effectiveness, Statistical test
