【摘要】 根据《中国震例》(1966～1999年)在中国大陆发生MS≥5.0地震188次震例资料,将其中与流体异常相关的126个震例中的803项流体异常按异常出现、异常转折至发震随时间变化和异常数量随震中距距离变化分布的时、空特征进行统计、分析。研究结果表明,无论是趋势性异常还是短临异常,在不同的时间段中,异常数量呈现出明显的阶段性分布特征;异常数量空间分布会随震中距的变化而不同。在统计研究中还表明,两者在时、空分布方面有较好的一致性。更多还原

【Abstract】 According to <Earthquake Cases in China>, which introduced 188 earthquake (M_S≥5.0) cases occurred from 1966～1999 in China’s continent, among which, 126 earthquake cases are related to the fluid anomaly and there are 803 fluid anomalies, their time-space characteristics are statistically analyzed based on the appearance and diversion of anomalies and earthquake generation with the changes of time and the anomaly amount with the changes of the epicentral distance. The results show that: no matter what the trend or short-term anomaly is, in the different time stage, the amount of the anomaly has obvious stage feature, the special distribution of the anomaly changes with the distance of the epicenter. And the consistence of them in time-space distribution is founded in the study of each earthquake case and different districts.更多还原
