摘要
本文利用华北及邻近地区21个地磁台1980—1987年总场F实测资料,研究了该区F的时空变化规律,并对1987—1988年磁场变化进行了推测。在此基础上,可求出各台的长期变化和外空干扰变化,提出了相应的改正、分析方法,以供在地磁监测预报地震中使用。
This paper discusses the time-space variation regularity of general geomagnetic field F in North China and predicts its variation in 1987-1988 by using the observed data of F at 21 geomagnetic stations in North China and adjacent areas in 1980-1987. Based on this, the long-term variation at each station and the external interference can be recognized and relevant methods for correction and analysis are put forth so as to apply them to the geomagnetic monitoring and earthquake prediction.
