| 摘 要： | 运用地震拟合优度的计算公式，首先确定了对异常反映最为明显的计算参数，接着对2008年11月10日大柴旦6．6级地震震中（37．55°N，95．80°E）附近3°×3°范围内的地震拟合相关系数进行了计算分析。结果表明，在周边300km范围内的ML≥．5级地震前一段时间内，该区域的地震拟合相关系数的计算结果都有明显的下降异常反映，特别是大柴旦6．6级地震前的异常反应幅度明显，形态清晰。因此，该区域的地震拟合相关系数可以作为周边ML≥5．5级地震中期预报的依据之一。

| Abstract: | Abstract： Using the formula of earthquake optimization mimesis, the authors have determined the precursory anomalous parameters, and calculated the optimization mimesis of Dacaidan Ms 6.6 earthquake in the epicentral 3°×3° area. And the results show that the calculation presented the obvious descending anomalies in neighboring region of 300km before ML ≥5.5 earthquakes, especially before Dacaidan Ms6.6 earthquake. So the curves of earthquake optimization mimesis may be regarded as one of the metaphase prediction index. |
