geospace

A complex coupling system is formed by the solar wind, magnetosphere and ionosphere in geospace. And an important process in geospace that is still not fully understood is the plasma transport between the plasmasphere and the ionosphere during different interplanetary disturbance and geomagnetic condition.

太阳风-磁层-电离层组成了地球空间的一个复杂的耦合体系，基于不同行星际条件或地磁条件下，等离子体层和电离层间物质输运机制仍未弄明。

With the innovation and wide application of GIS, and the rapid development and integration of relevant information collection systems, GIS will integrate various kinds of information in geospace ( even in a wider rage) and have gigantic database.

随着GIS的技术革新和广泛应用，以及相关信息采集技术的迅猛发展和集成，GIS将把地球空间（甚至更广）大千世界各方面信息汇集于一体，将拥有庞大的数据库。

We analyze the magnetic storm on April 11, 2001 to investigate how the compression of the magnetopause would influence the magnetic field in the geospace and on the ground when it was strongly compressed.

集中分析2001年4月11日的磁暴事件，研究当磁层顶发生强烈压缩以后，在地球空间和地面上产生的磁场影响。
