摘要
在多年对东北地震大形势研究的基础上,根据1900年以来的历史地震资料所显示的周期性活动特点,用正弦函数描述其地震活动规律,并结合时间序列的周期图及其他一些地震活动性分析方法,对东北地区地震活动规律及发展趋势作了详细研究。
On the basis of analysis on great situation of earthquake in Northeast China for years,according to the periodicity activity characteristics shown in historical earthquake data in this region since 1900, its seismicity law is described by a sine function, and to combine the periodogram of time series and others analysis methods of the seismicity,the seismicity law and development trenegion have been studied in detail.
