摘  要:地震电磁辐射观测对短临预报非常有意义。讨论了以计算机为核心的数字 化观测系统的可行性与必要性,并给出了实际观测系统的设计方法。数字化系统具有观 测灵敏度高、便于观测信号的实时分析识别、便于应用算法提取短临预报的有用信息和 便于观测台网间数据交流与处理等优点。基于对观测信号的时域、频域分析的比较,给 出了干扰信号与异常电磁辐射信号的判别方法。The seimo-electromagnetic radiation observation is important for short - impending prediction. The feasibility and necessity of a digitized observation system on a PC as its core is probed in this paper, and the design method of a practicable system is given. Digitized systems have the advantages of high sensitivity, in favour of not only observing signals real - time analyzing and recognizing, and short - impending prediction information extracted by using algorithms, but also data transmission and processing within observing networks. Based on observed signals analysis and comparison in time - domain and frequency -domain, the method of distinguishing interfere signals and abnormal electromagnetic radiation signals Is given.
