| 摘 要： | 通过对包头６．４级地震前较大范围前兆资料的研究，认为一个强烈地震在发生之前，围绕震中区不同区域内，将出现具有不同特点的前兆场异常群。其近场（Δ≤１００ｋｍ）的主要特征是具有较长时间尺度的趋势性异常；中场（１００ｋｍ〈Δ≤２００ｋｍ）的主要特征是趋势和突发性异常并重；而远场（Δ〉２００ｋｍ）则一般无趋势性异常，只有急剧变化的短临异常。

| Abstract: | In this paper ,by studying precursory data of large range before Baotou earthquake (Ms6.4),the Authors suggested that anomalies group of precursor field may appear with different fea-Tures before a strong earthquake in different areas around the epicenter ,The main char-Acter of the near field (0<100km )is a tendency anomaly with relatively long time scale ;the main character of the middle -far field (100km<0<200km )showed both tendency and sudden anomalies ,but the distant field ,generally speaking ,showed no anomalies ,only showed short term and imminent prexursors of the earthquake. |
