| 摘 要： | 对1999年4月8日南极中山站极光亚暴期间不同谱线的极光强度比值进行讨论,并据此讨论亚暴期间沉降粒子能量随时间变化的情况.得出I(557.7 nm)/I(427.8 nm)和I(630.0 nm)/I(427.8 nm)比值在平静时期分别在5-22和1-2.76之间变化,该变化不是由原子氧浓度空间分布变化所引起,而可能...

| Abstract: | Intensity ratios of different auroral lines during an auroral substorm observed at Antarctic Zhongshan Station on April 8,1999 are discussed together with the variation in penetrating electron energy.It was found that the ratio of I(557.7 nm)/I(427.8 nm) during the quiet period ranged from 5 to 22,and the ratio of I(630.0 nm)/I(427.8 nm) ranged from 1 to 2.76,and the cause of the change was not variation in the atomic oxygen concentration,but was possibly due to variation in the penetrating electron energy ... |
