摘要
应用广义分维的概念于地震活动时间分形的研究可避免确定无标度区的困难。海城地震前后地震活动的广义分维D_o(ε)的变化表明,时间标度区间为2—16天时,D_o(ε)的变化可以反映大震酝育过程中地震时间分布的不均匀性,并表现出震前降维的前兆变化特征。
To apply the generalized concept of fractal dimension to the study of seismic active time fractals can overcome the difficulties in determining non - scalearea . After analysing the variation on the generalized fractal dimension D0(ε)around Haicheng earthquake ,it showed that D0(ε) do reflect the inhomogeneous distribution of time in which a large earthquake may be in preparation by declining dimension values before its occurrence .
