| 摘 要： | 本文应用关联维数计算方法,分别计算了雷波5.4级地震、康定5.2级、5.8级地震和大邑6 1/4级地震的余震序列的关联维数D_2,并给出了相应的离差和相关系数。它们的关联维数分别为2.26982、1.93915、2.28738和1.5367。在这4个地震序列中,发生强余震的序列的D_2大于无强余震的序列。

| Abstract: | This paper introduces a method calculating the relative fractal factor and has calculated the relative fractal factors(D2)of after-shock sequences of the Leipo earthquake(Ms=5.4), two Kangding earthquakes(Ms=5.2, 5.8)and the Dayi earthquake(Ms=6(1)/(4)), using this method. The D2 factors, for above mentioned four earthquakes, are 2.26982, 1.93915, 2.28738 and 1.5367 respectively. Relative coefficient and related departure of every D2 are calculated and given. The D2 factor of aftershock sequence in which the strong aftershock occurred is larger than that of aftershock sequence in which the strong aftershock did not occur. |
