| 摘 要： | 汶川8．0级地震前，距离震中只有35km的金河电磁波台记录到了宝贵的电磁扰动信息。本文分析了汶川5．12大地震前后该台的电磁波异常变化特征，表明：①强震前确实有电磁辐射异常存在，震前存在丰富的电磁扰动信息；②电磁扰动前兆异常在时间进程上有明显的阶段性变化特征，这可能是地震孕育不同阶段特征的反映。 |

| Abstract: | Before the Wenchuan MS 8.0 earthquake, valuable disturbances of electromagnetic wave were recorded at Jinhe Seismic Station only 35 km away from the epicenter. We analyzed the anomalous character of electromagnetic radiation of Jinhe Seismic Station during the Wenchuan MS 8.0 earthquake. The results show that, firstly, the electromagnetic radiation at Jinhe Seismic Station appears anomalous character before the earthquake. Secondly, electromagnetic radiation anomalies have clearly staggered change before the earthquake. |
| Keywords: | the Wenchuan 8.0 earthquake electromagnetic radiation anomalous character |
