| 摘 要： | 用一阶差分法分析了马陵山台与泰安台地磁场垂直分量Z的变化,用转换函数法分析地磁场3个分量ΔZ、ΔD、ΔH的变化,用加卸载响应比法研究了地磁场极值的变化。 研究发现在中强地震前马陵山台的地磁场值存在明显的异常变化。 此结果对地震预报有一定的实用价值。 |
| 关 键 词： | 地磁场 地磁异常 转换函数 加卸载响应比 |

| Abstract: | By using difference method, transfer function and load-unload response method, we analysed the changes in the geomagnetic vertical component Z, the geomagnetic ΔZ, ΔH, ΔD components and geomagnetic extreme value at Malingshan seismic station. It is re-vealed that there is obvious anomaly in Malingshan’s geomagnetic field before some moder-ately strong earthquakes. Result shows that those anomalies are of a certain significance in earthquake prediction. |
| Keywords: | Geomagnetic field Geomagnetic anomaly Transfer function Load unload response ratio |
