在重新分析了强地震前地壳形变异常的基础上,获得了如下一些见解:地壳形变异常不一定存在完整的趋势、短期和短临等异常类型,但趋势异常普遍存在;地震前地壳形变异常形态可能为缓慢稳定的变化,不一定存在诸如异常幅度变大、异常速度变快等;地壳形变异常不一定具有时空迁移或有序性等。
在重新分析瞭彊地震前地殼形變異常的基礎上,穫得瞭如下一些見解:地殼形變異常不一定存在完整的趨勢、短期和短臨等異常類型,但趨勢異常普遍存在;地震前地殼形變異常形態可能為緩慢穩定的變化,不一定存在諸如異常幅度變大、異常速度變快等;地殼形變異常不一定具有時空遷移或有序性等。

Some knowledge is gained on the basis of the re-analysis of crustal deforma-tion anomaly before strong earthquakes:There is not necessarily a complete trend anomaly, short term anomaly,short-impending anomaly etc;But the trend anomaly of crustal deform-ation exist in common.The anomaly of crustal deformation maybe slow steady change. There does not exist necessarily the phenomenon such as larger abnormal amplitude,faster abnormal speed etc.The anomaly of crustal deformation does not necessarily have space-time migration or ordered characteristics.
