geomagnetic main field

基本解释

The main error sources in the geomagnetic field model were introduced, too.
介绍了地磁场模型误差的主要来源。
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，主相时所观测到的极光，并不是由于地磁场的平缓下降使小投掷角电子注入大气层而形成的。

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.
自从辛格用辐射带内电性粒子运动所形成的电流环，成功地解释磁暴主相形成的机制以来，这些带电粒子的来源就成为磁暴主相理论的一个重要问题。
