摘　　要：文中对地磁绝对测量前兆异常形态类型作了进一步的总结,着重研究了非前兆异常形态的类型。虽然两者的形态多数有明显的差别,但有一种类型是相似的,应引起高度重视,注意识别。对两者形态的研究,有助于快速有效地识别异常和落实异常,以及提高预报水平。The shape types of precursory anomalies from the absolute geomagnetic measurement are summarized and the study on the shape types of non-precursory anomalies is emphasized. Although two kinds of anomaly shapes are usually different, there is a similar type, to which should be paid attention for recognition. The study on two kinds of anomaly shapes will be helpful to recognize and decide the anomalies rapidly and effectively and to improve the earthquake prediction level.
