太阳射电快速事件的初析

本文着重介绍了紫金山天文台在１０cm波段上观测到的太阳射电快速结构事件资料，并对其进行了初步的分析.得到的一些结果如下:１．快速事件的宽度介于几十毫秒一几百毫秒的变化范围内；每秒出现的频数介于２１－１之间；２．从ｓｐｉｋｅｓ事件的形态上，也有着不同的结构特征；有的ｓｐｉｋｅ结构比较简单，基本上是一个个的单脉冲，而有的则比较复杂，即在每个ｓｐｉｋｅ尖峰上，还叠加有亚－精细结构。

A PRELIMINARY ANALYSIS FOR THE SOLAR RADIO FAST STRUCTURE EVENTS

In this paper, we present some solar radio spike events at 10cm wavelength observed at Purple Mountain Observatory, and made a preliminary analysis for them.Some interesting results thus have been obtained as follows: 1. The widths of the spike events varied from tens of ms to hundredes of ms, and the occurrence rates of spike structure of the events ranged from 21-1 per second; 2. There are different characteristic structures on the morphology of the spike events. For instance, some events consist of single impulse with simple rise and fall time structure, while others are rather complex structures with subfine structure superposed on the peaks of the spike events.
