| 摘 要： | 前兆观测曲线中出现种阶跃变化，简称阶变，实际体应变分钟值观测曲线在地震发生前后记录到的阶变是地下应力应变急剧调整的一种特殊运动变化的过程。研究分析阶变各种形态，对于探索这些区域再次发生地震的预测研究有实际意义。

| Abstract: | Step change appears in precursor observation curve. The step change, occurred before and after earthquake, in the observation curve of body strain minute record is the rapid adjustment process of underground stress and strain. Analysis of the various shape of step changes is practically significant for prediction research of the earthquake recurrence in this region. |
