MDCB型地震前兆监测仪映震效果分析
DISCUSSION OF THE CORRESPONDENCE EFFECT ABOUT MDCB EARTHQUAKE PRECURSOR SUPERVISING INSTRUMENT
【摘要】 对MDCB-Ⅱ型地震前兆监测仪观测获得的类地应力值、异常频度和8方位异常值等参数进行了比较深入的分析及其与地震关系的研究。资料反映的事实表明,在一定距离、一定强度的地震的短临阶段,确实存在着电磁波异常现象,其动态趋势、变化次数、异常突变和异常方向性反映等参数,可为地震预测预报研究提供科学判据。
【Abstract】 It is carried out to analyze systematically the data of pseudo - crustal stress, anomalus frequency and abnormal eight - directtion, which were obtained by observation of MDCB - Ⅱ earthquake precursor supervising instrument, and to reasearch the relation betwee those and the earthquakes. The results show that the electromagntic wave anomaly really exists in a certain scope and the short - impending stage of earthquake with a certain shock shength; its paramters of dynamic tendency, chang of frequency,abrupt anomaly and anomalous directivity could provide the reliable basis for the researching of earthquake prediction.
