摘　　要：介绍了国外利用卫星上观测的电子流量和磁场资料进行地下结构探测研究的一些成果.研究表明,卫星上记录到的不同能量电子流量脉冲突变与地下结构、深大岩石圈断裂带有密切的对应关系.卫星磁场观测具有覆盖全球的优势,随着卫星磁场数据观测精度的提高,卫星磁测在全球磁变模型的建立、研究大陆内部结构、大陆和海洋边界带、地幔过渡带等方面的将发挥越来越重要的作用.卫星观测将成为全面、整体探测研究地球内部结构有效的手段之一.It is introduced that some results of electric structure obtained by using electronic flux and geomagnetic field measured on satellite in this paper. It shows that sharp variation of electronic flux in different energy impulse measured on the satellite is associated with substructure and lithosphere fault. The advantage of geomagnetic field measured on the satellite can be covered globe surface. With the improvement of precision for observation of geomagnetic field on the satellite, it will be changed into more and more important role in setting up globe geomagnetic reference model and studying on continental structure, the margin between land and ocean, transition zone of crust and mantle. The satellite observation will be one of the most important methods for effectively studying earth structure in full and macrocosm.
