| 摘 要： | 选取了两种方案得到武定地震序列，并利用相空间重建法重构武定地震序列，探讨其吸引子的存在性。结果表明第二种方案得到的武定地震序列不存在吸引子，而第一种方案得到的武定地震序列确实存在吸引子，它具有自相似分形几何结构，其分维数d=2．856，所以为奇异吸引子。根据奇异吸引子的性质，探讨了武定地震发生的整个过程。并且论证了用此法研究武定余震分维数时，所必须取的维数。的范围。

| Abstract: | The Wuding earthquake sequence obtained by two scenarios is selected, and the sequence is reconstructed by phase space method. We are trying to explore the existence of its attractive factor. The results show that there does not exist the attractive factor for the Wuding earthquake sequence obtained by the second scenario. And there does exist the attractive factor for Wuding earthquake sequence obtained by the first scenario, which has auto-similarity fractal geometry characteristics. Its fractal number d=2.856, therefore it is singular attractive factor. We have explored the whole process of Wuding earthquake occurrence according to the property of the singular attractive factor. Further, the range of fractal number n used in the study of Wuding aftershock sequence is discussed. |
