摘　　要：构造了一个我国东部强震时间序列,采用配分函数方法判定了1500年以来b类以上灾难性地震时间序列的单分形特征,并利用R/S方法确定了一个代表强震变化趋势的时间序列的Hurst幂,对此时间序列变化规律进行了分形分析.A time sequence of strong earthquake of Eastern China is constructed, and by using the partition function method, the single fractal characteristic of the time sequence of earthquake of classes a and b from 1500 to 2008 is determined. The Hurst exponent of the time sequence which indicate the trend of strong earthquake is calculated by using the R/S method, and the discipline of the time sequence is analyzed by using fractal theory.
