| 摘 要： | 根据岩石受力过程的应变、破裂时产生的局部地磁场异常变化和电磁辐射现象 ,运用地磁短周期转换函数法和地磁场垂直分量加卸载响应比法结合电磁辐射现象的分析 ,可达到对地震的中短临异常跟踪预报的目的。由上海及邻近地区 2 0世纪 90年代发生的二次中强地震震例可得到较好的验证。

| Abstract: | Based on the anomalous variation of the local geomagnetic field and electromagnetic radiation phenomenon induced by the strain and fracture of rock subjected to force, the traced predictions of imminent short medium anomalies for earthquake are realized using the transitive function method and response ratio method of load and deload of vertical component of geomagnetic field and the analysis for the electromagnetic radiation phenomenon. |
