在1985年4月24日的IV型爆发期间，我们在234 MHz处观察到一个非典型的、强的、持续近6小时的连续辐射，其中包括几组宽带脉动、斑马图案、纤维爆发和一种新的精细结构现象。宽带脉动群的功率谱显示出不存在简单的结构。在0.3 s和0.4 s之间只有一个共同的周期分量。慢漂移的窄带光纤爆链被描述为一种新的精细结构的频谱图和同时记录的单频强度分布。这种新的精细结构的定性模型的建议。
During the type IV burst on 24 April, 1985 we observed at 234 MHz an untypical, strong, nearly six hours lasting continuum emission incorporating several groups of broadband pulsations, zebra patterns, fiber bursts, and a new fine structure phenomenon. The power spectra of the groups of broadband pulsations reveal no simple structure. There is only one common periodic component between 0.3 s and 0.4 s. Slowly drifting chains of narrowband fiber bursts are described as a new fine structure by spectrograms and simultaneously recorded single frequency intensity profiles. A qualitative model of this new fine structure is suggested.
