| 摘 要： | 本文利用欧洲的ＥＩＳＣＡＴ雷达观测资料及与这配合的地磁观测数据，用电离层参数直接计算和地面磁场反演两种方法导出了极区电离层Ｈａｌｌ电导率，特别显示出在强对流电场激发的Ｅ层等离子体不稳定波对电子加热情况下，电导率明显增高。

| Abstract: | The data from the EISCAT radar and corresponding ground-based geomagnetic observations are used for deriving the ionospheric Hall conductivity.There are two calculating methods employed,one is the direct estimate from ionospheric parameters,the other is indirect estimate from ground geomagnetic field.The results show that when there appears the electrons heated by the E region plasma unstable waves,the Hall conductivity increases conspicuously. |
