摘　　要：利用地震矩加速释放模型,对2000年9月12日青海兴海的6.6级地震进行"回溯性"预测研究。采用不同的空间半径进行了"时—空"扫描计算,结果表明该地震前具有显著的地震加速释放现象,随着扫描半径的不同,异常表现为"异常出现—消失—出现—发震"的特点。分析认为地震矩加速释放模型在实际地震预测工作中具有一定的参考意义。In this paper, based on the Accelerating Moment Release （AMR） model, we study the prediction of the Xinghai Ms 6.6 earthquake on Sep.12, 2000 . Different spatial scale is used to carry out ＂time-spatial＂ scan calculation. The results show that there is obvious AMR phenomenon before earthquake. Because of the different scan radius, the AMR phenomenon has the characteristic that it appears, and then disappears, and then appears, finally happens. So the AMR method has some kind of useful value for daily practical works in the future.
