本文用数学拟合方法,求出1975—1978年辽宁地区12个流磁测点地磁年变率的分布函数,通过IBM 计算机处理结果表明:此资料对研究地磁场年变特征,寻求地磁资料处理方法是有意义的,对垂直分量(Z 以下同)的时空变化进行了讨论,试图说明1976年7月28日唐山7.8级和1978年5月18日官屯6.0级两次中强以上地震辽宁地区地磁垂直分量变化趋势和特征。
In this paper, the mathematical fitting method was used to find out the geomagnetic annual variability distribution function of 12 flux magnetic detection points in Liaoning Province from 1975 to 1978. The results of IBM computer processing show that this data is useful for studying the geomagnetic changing characteristics and seeking geomagnetic data processing The method is significant. The temporal and spatial variations of the vertical component (Z and below) are discussed in an attempt to explain the magnitude of Tangshan 7.8 on July 28, 1976 and two moderate to strong earthquakes of magnitude 6.0 on May 18, 1978 in Liaoning Province. Regional Geomagnetic Vertical Component Variation Trends and Characteristics.
