摘要
用非线性方法分析了1989年3月13日大磁暴发生时地磁场的各分量,研究了非线性物理过程,讨论了非线性特征及其与纬度和K指数变化的关系。
In order to study the nonlinear physical processes connected with geomagnetic storm, the geomagnetic components during the magnetic storm on Mar.13,1989,its relationship between the variation of the nonlinear feature with latitude and K index have been analysed. It′s concluded that the geomagnetic field lies in a low dimensional chaos.
