geomagnetic main field

基本解释

The main error sources in the geomagnetic field model were introduced, too.
介紹了地磁場模型誤差的主要來源。
This means that the excitation of aurora during the main phase can not be attributed to the precipitation of electrons into atmosphere caused by the slow change of geomagnetic field.
因此，主相時所觀測到的極光，竝不是由於地磁場的平緩下降使小投擲角電子注入大氣層而形成的。

Since Singer explained the main phase ring current by charged particles trapped in geomagnetic field, the origin of these particles has become one of the important problems of main phase theory.
自從辛格用輻射帶內電性粒子運動所形成的電流環，成功地解釋磁暴主相形成的機制以來，這些帶電粒子的來源就成爲磁暴主相理論的一個重要問題。
