| Abstract | 本文收集了1986年2月4日大耀斑的Ｈα、微波、Ｘ射线和γ射线全波段的观测资料。利用暗条电流环模型分析了该耀斑的物理过程。测量了活动暗条的上升运动，求解了动量方程和能量方程。结果表明：(1)1986年2月4日的3B/X3耀斑可能是由暗条电流环之间的合并不稳定性所致;(2)电阻撕裂模不稳定性是一种有效的耀斑前预热机制;(3)耀斑的高能观测资料进一步表明了电流环合并不稳定性是引起该大耀斑期间所有高能粒子几乎同时加速的可能的有效机制。 |
| Other Abstract | In this paper，the observational data of Ha，radio，soft X-ray，hand X-ray and r-ray for the 3B/3X flare on Feb.4，1986 are collected.This flare is studied coin-prehensively by using the flare-filament current model.Ths rising noverent of the filaments is measured.The momentum equation and the ererg equatics ot filamentcurrent have been solved.The results skcw that（1）Tie 3B/X3 tlare on Feb.4，1986 was possibly caused by the carent ioop coalescence instability between two filament current loops:（2）The resistive tea:insg instability is an efficient pre-heating mechanism of pre-flare phase，（3）The high energy data on Feb.4 flare further corrobrate that the current loop coalescence instability is a possibly efficient mechanism for the simultaneous acceleration of high energy particales during the flare. |
