| 摘 要： | 本文对1989年1月-1990年6月期间的11个微波双峰事件进行了初步的分析,发现大部分双峰事件的两个峰随频率的演化呈现出竟争的趋势。这一观测特征,可由不同的非热电子分布、或相同非热电子分布,但在相同频率上不同光厚导致谱相交特征得到合理的解释,井可得到双峰事件中两个峰产生在不同源区的推论。

| Abstract: | In this paper3 a preliminary analysis of eleven microwave eveals with donblepeak structures during the periods of Jan. 1989--Dec. 1990 are made. The resultsshown that the evolution of peak in most double-peak events with frequency exhibited a competition trend. Such a observing character may be interpreted resonablyby property of cross-spectra due to different distribution of nonthermal electronsor same distribution of nonthermal electrons but different optical thickness at samefrequency. Therefore, a deduction may be obtained that two peaks in the microwaveevents with double-peak structures originate from different source region, respectively. |
