我国自一九六六年邢台地震后,在全国很多地区开展了地磁预报地震的研究工作,创造和积累了不少经验。与此同时,地磁台站得到相应发展,在这些台站中,有相当一部分是相对量记录,无绝对观测仪。因此,在震磁关系研究分析中,普遍采用的是北京时整点值相对量资料。震磁关系的研究,观测技术是基础,而前兆现象的研究是地震预报的核心。现已提出的
Since the Xingtai earthquake in 1966, China has carried out research on geomagnetic forecasting earthquakes in many areas of the country and has created and accumulated quite a lot of experience. At the same time, geomagnetic stations have been developed accordingly. A considerable part of these stations are relative quantities recorded and there is no absolute observer. Therefore, in the study of the relationship between the magnetism and magnetism, the data of the relative value of the whole point value in Beijing are commonly used. The study of the relationship between the magnetism and the magnetism, the observational technique is the foundation, while the study of the precursor phenomena is the core of the earthquake prediction. Now proposed
