| 摘 要： | 本文讨论了1990年7月30日伴随日面2B级双带光学耀斑发生的3.2cm波微波大爆发事件的观测特征,它呈现为显著的脉动形态。并对它进行了数据处理,发现射电爆发流量S与脉动的特征参量:平均重复率R,调制度△S/S和能量△E之间有良好的统计相关性。对此作了讨论和初步的解释。

| Abstract: | An outburst with rich pulsations has been observed at 9.375 GHz on July 30, 1990. After analysing these pulsations, some interesting results are obtained: (1) The flux level of the burst rises as repetition frequency of pulsations increases, following a linear relationship; (2) The modulation degree of pulsations is inversely propotional to the flux level; (3) There is a good linear relationship between the energy of individual pulse and flux level too. A simplest interpretations are proposed. |
