中文摘要	采用天宫一号轨道大气环境探测器的在轨探测数据,分析了2012年3月和10月地磁扰动期间的热层大气成分数据,对磁暴期间N2异常增变的涨幅、时间、空间特性,低纬地区N_2异常增变特点,以及冬夏半球N_2异常增变的差异进行探讨,探讨认为:N_2数密度的异常增变与地磁扰动及其扰动程度密切相关,增变现象通常出现在夏半球高纬区域上空,磁扰期间所出现的N2数密度异常增变现象与地磁扰动对热层大气加热机理紧密相关.
英文摘要	The response of N_2 number density in thermosohere during two geomagnetic disturbance on March and October 2012 is analysed in this paper, data taken by Atmospheric Environment Detector on board Tiangong-1 spacecraft are used. Discuss the abnormal increase range, time and space characteristics, low latitude distribution and features of summer and winter hemisphere of N_2 number density during the geomagnetic storms. These results are as follows: the abnormal increase of N_2 number density is closely related to geomagnetic disturbance and its intensity, abnormal increase phenomenon usually appears in the high latitudes region of summer hemisphere, N_2 number density increase during the geomagnetic disturbance is closely related to the mechanism of atmospheric heat.
