【摘要】 <正> 前言 1980年以来,京、津、唐地区流动地磁测量(简称流磁)进行了布局调整,除外围地区有一定的控制测点外,区内测点加密至30—50公里。本文引用的是河北省地震局、国家地震局综合流动测量队(简称流动队)1980—1983年的实测资料。在所用资料中,河北省地震局共17个测点(图1),观测总场F,每年观测4次,利用红山自设日变站通化到每季更多还原

【Abstract】 Based on the data of mobile geomagnetic measurements carried out by Seismological Bureau of Hebei Province and Mobile Seismic Observation Brigade, State Seismological Bureau, in Beijing-Tianjin-Tangshan Kegion from 1980 to 1983, of which the mean square error is 2 to 3 gamma, the plane map of annual variation characteristics of geomagnetic field in this Eegion is plotted, and the method for processing data is discussed as well in this paper.更多还原
