摘要
根据乌鲁木齐地磁台所编的1989年《地磁观测报告》,采用地磁静日场的水平分量(H)和垂直分量(Z)资料,选用其特征量——日变幅和相位,对乌鲁木齐地区地磁静日场S_q的变化特征进行初步统计分析表明,该工作对于进一步认识和研究乌鲁木齐地区地磁静日场的变化规律,为利用地磁预报地震提供背景值资料具有一定意义。
In this paper, adopting the data of magnetic horizontal (H) and vertical (Z) components from 《Geomagnetic Observation Report》 edited by Urumqi geomagnetic observatory in 1989,we chose phase and daily magnetic variation to do the primarily statistic analysis on geomagnetic quiet daily Sq variation field in Urumqi district , so as to obtain the further knowledges and regulations of geomagnetic quiet daily variation field, this work is of certain significance in providing background data for earthquakes forecast by means of geomagnetic approach.
