【摘要】 本文在研究东亚地磁场长期变"双焦"特征的基础上,着重分析了辽宁及邻区1970-1979年F、Z之长期变图象及特征.并利用辽宁省地磁台站1980-1988年资料给出长期变化的量级,为震磁预报提供背景场依据.更多还原

【Abstract】 This paper is based on double focus charactevistic of geomagnetic secular change in East-Asia region, and analyses F’s and Z’s secular change from 1970 to 1979 for pattern and characteristic in Liaoning and near area. we have obtained the order of gocmagnetic seculbr variation by observing data of geomagnetic stations in Liaoning from 1980 to 1988. The results as background field are useful for predicting earthquake.更多还原
