【摘要】 应用有关软件分析新疆乌什研究区地震活动时间分布的多重分形谱Ｄｑ－ｑ和ｆ（α）－α。发现两次６级强震发生前，多重分形谱发生显著变化。主要特征是对一定的ｑ区间奇异性强度因子α取值变宽，Ｄｑ－ｑ曲线变陡，ｆ（α）－α的左端点或右端点下降。双标度五分Ｃｏｎｔｏｒ模型研究证明，强震前地震多重分形谱异常的物理本质是地震分形结构的不均匀性增大，即更复杂了，而复杂性的增加恰恰是具有普遍前兆意义的。更多还原

【Abstract】 When applying some softwares concerned to multi-fracial spectrum Dq-q and f(a)-a on time distribution of seismicity in Wushi seismic research region, Xinjiang, it is discovered that before two strong earthquakes (M≥6.0),multi-fracial spectrum varied greatly. Its main characters are the wide value scale of singularity strength factor for some certain regional intervals, while curve of Dq-q becomes sharp, the left or right end of the curve f(a)a drops. It proved by Contor mode of double scale five-division that before strong earthquakes, physical property of seismic multi-fracial spectrum anomaly is of some inhomogeneous increasing in seismic fractal structure,that is to say,the increasing of complexity is just of general precursory significance.更多还原
