| 摘 要： | 利用甘肃省内地电数字化资料观测结果，对2003年11月13日10时35分发生在岷县-卓尼Ms5．2地震进行初步分析，结果表明，在该地震发生前，地电前兆出现了18项短临异常，对这些短临异常特征进行分析研究，发现其临震异常较为明显，从异常开始至结束表现为时间短、幅度大、恢复快这一特点。可为地震短临预报提供重要的参考判据。

| Abstract: | The digital resisitivity observatory data in Gansu province had been analyzed for the shock occurred in 10:35 Nov 13th 2003 M_S 5.2 in Minxian-Zhuoni of Gansu Province. The results show that resisitivity precursory presented 18 short-term anomalies. Analyzing these anomaly characteristics, we found that the anomalies were obviously related just before the shock, all anomalies behaved short lasting time, large amplitude, quickly recovery. These results can be used as important criterion to earthquake short-time prediction. |
