【摘要】 本文分析的是１９９２年２月９日至１９９３年２月９日在南极中山站记录的各种地磁脉动的观测资料，并对各种地磁脉动的激发机制进行了初步讨论。通过南极中山站地磁脉动观测资料分析，了解高纬地区地磁脉动的形态特征，对南极极隙区高空大气电磁环境、太阳风和磁层相互作用等现象有进一步的认识。更多还原

【Abstract】 The data of various geomagnetic pulsations observed at Zhongshan Station from Feb.9,1992 to Feb.9,1993 are analysed in this paper and the excitation mechanisms of pulsations at Antarctic polar cusp are discussed primarily. By the observation and analyses of geomagnetic pulsations at Zhongshan Station, the phenomena of upper atmospheric electromagnetic environment, interaction between solar wind and the magnetosphere etc. at Antarctic polar cusp can be further realized.更多还原
