摘　　要：磁场和电场，是电磁场同一事物中相互依存的二个方面。作为电磁扰动场地震短临前兆新方法的研究与应用，亦应同时探测、综合分析，才有利于学科的深入发展。经过长期多台区比较系统地对比观测和资料的综合分析研究，证实了一定范围内一定强度的地震，其电磁辐射前兆异常反映，包含磁场分量变化和电场分量变化二个方面。而且，磁电分量信息的同步异常，往往集中出现在比较强地震的短临时段，因此，采取磁场分量与电场分量同时接收，应是地震电磁扰动研究与应用的发展方向。The magnetic field and the electronic field are two interdepending aspects of the electromagnetic field. It is helpful to further develop this specific topic that we should observe and analyze them comprehensively as a new seismic short-term and impending precursor method ofelectronic-magnetic disturbance field. It has been proved that the precursory anomalies of electro-magnetic radiation include the change of both magnetic component and electronic component within certain distance before comparatively strong earthquakes by systematically comparing observations and comprehensively analyzing and studying based on the data from the longterm observations at several stations. In addition, the magnetic and electronic anomalies usuaLly emerge in the short-term and impending phase before a comparatively strong event, so it isthe development direction of the study and application of seismic electronic-magnetic disturbance while the magnetic component and the electronic component should be received simultaneously.
