摘要
本文对太阳22周峰年期云南天文台日冕射电频谱仪观测到的60个快速事件作了分析,从中获得了尖峰辐射、增强噪暴、快速起伏、类尖峰、叠加脉冲五种快变型别.对它们的亮温度、叠加特性、特征时间、辐射源尺度、偏振特性以及辐射机制六个方面作了分析研究后。对射电爆发、缓变分量和宁静太阳的辐射特征参量也作了研究,从而得出基本分量特性。
Sixty rapid events observed with Corona-Radiospectrometer at Yunnan Observatory during solar cycle 22 are analysed in this paper.Five types of rapidly varying component are observed.They are spike emission,enhanced noise,rapid fluc tuation,spike-like and superimposed impulse.Some characteristic parameters of these events such as brightness temperature,superimposed character,characteristic time,emission source size,polarization are investigated and radiation mechanism,the characteristic parameters of radio burst,slowly varying components and quiet sun are studied as well.Based on the study,certain features of basic components are confirmed.
