【Abstract】 the application to recognize seismic anomaly with gray system and periodical error superposition mode is studied. The precursory data observed by Yongnian seismostation etc. are processed with this method. The results show there are obvious anomalies in these observations before some earthquakes. In addition, some other relevant questions are also discussed here.更多还原
