太阳电子事件粒子源区的位置

THE POSITION OF PARTICLE SOURCE IN SOLAR ELECTRON EVENTS

对ＩＳＥＥ—３的引个太阳电子事件资料，进行了系统地分析．通过Ｓａｈａ平衡模型分别计算了高Ｆｅ事件和贫Ｆｅ事件源区的平衡温度大小，指出两类事件粒子源区不相重合，高Ｆｅ事件的粒子源区位于高色球层，贫Ｆｅ事件粒子源区在色球层－日冕之间的过渡区．对高Ｆｅ事件和贫Ｆｅ事件的形成作了初步的设想．

In this paper, the ISEE-3 energetic particle data from 51 solar electron events are analysed. And the equilibrium temperature of Fe-rich events and Fe-poor events are calculated based on the model. The source position of particles in the Ferich events is found to be in the high-chromosphere, while the source position of particles in the Fe-poor events in the region between the chromosphere and the corona. The source positions of particles in both the Fe-rich events and Fepoor events are found to be always different from their corresponding flare regions. According to above results, the processes of formation for the two types of electron events are proposed.
