摘    要:1980年11月6日耀斑后冕拱在母耀斑(AR2779)开始后3小时形成,并在形成后11小时和25小时两次激活,两次激活均由带耀斑的增长环系所致。本文提出了激顺热和Petschek重连是该冕拱有效的激活机制,导出并求解了考虑辐射损失,热传导,激光波加热和Petschek重连加热的冕拱能量方程。理论计算结果与Svestka根据SMM空间资料所给出的该冕拱的激活曲线基本符合。

关 键 词:耀斑  耀斑后冕拱  激活机制

Abstract:The post flare coronal arch of 6-7 Nov., 1980 was formed at three hours a-fter the onset of the parent flare (AR2779) and revived 11 hr and 25 hr after its formation. Both these revivals were caused by two-ribbon flares with growing systems of loops. It is proposed in this paper that shock wave, which was produced by the parent flare, and Petschek reconnection are effective revival mechanisms for post flare arch of 6-7 Nov., 1980. The energy equation taking into account radiati ve cooling, heat conduction, shock wave heating, and Petschek reconnection is deri-ved and computed. The calculated results are in agreement with observational cur ves given by Svestka according to SMM data.
Keywords:Solar flare  Post flare arch  Revival mechanisms  Energy equa-tion
