再论MDCB地震监测仪的映震效果

Re-discussion on the effect of corresponding earthquake by MDCB earthquake precursor monitoring instrument

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 data observed by MDCB earthquake precursor monitoring instrument within forty-two months in Langfang have been analyzed in this paper. The results show that electromagnetic wave parameters such as pseudo-crustal stress, abnormal eight-direction and anomalous frequency, which recorded by the MDCB, are corresponding to the moderate and strong earthquakes. The dynamic changes of these parameters can provide the criterion to estimate seismic distance, earthquake intensity and earthquake direction in the future. Finally, the preliminary results of the quantitative relation between the anomaly of electromagnetic wave parameters and the earthquakes occurrence have been given.
