摘　　要：通过研究地震远场前兆异常、超长期 ( 8～ 2 0 a)前兆异常和前兆异常判别上的差异 ,进一步揭示远场前兆异常的意义、前兆异常曲线的内涵和地震间的相互关联及地震预报的复杂性。The far field precursory anomalies, super long term precursory anomalies lasting for 8～20years, and the judging methods of the anomalies are analyzed in this paper. Themeaning of far field anomalies, the implication of precursory curves and the correlation between the earthquake and the complexity of earthquake prediction are also discussed. This aspect of discussion is beneficial to the further research on physical features of precursors and the practice of earthquake prediction.
