分析了 Ｍ Ｄ Ｃ Ｂ 型地震监测仪在廊坊连续４２ 个月观测期间， 所记录的类地应力值、８ 方位异常值和异常频度等１４ 种电磁波地震前兆异常参数的动态趋势、方向性反映、临震变化与一定范围内一定强度地震的对应关系， 并得出了电磁波前兆异常参数与地震数量关系的初步结果。
The dynamic trend and directionality of 14 earthquake precursors anomalies such as geostress, 8-direction anomaly and anomaly recorded by MCD C-type seismic monitor during the 42-month observation period of Langfang were analyzed. , The correlation between the pro-seismic change and a certain intensity earthquake within a certain range, and the preliminary results of the relationship between the anomalous parameters of the electromagnetic wave and the earthquake magnitude are obtained.
