摘要
用行星际闪烁观测耀斑激波时,如果激波压缩区覆盖了主要散射区的大部或全部,则激波前后闪烁指数会发生大的改变,在这种情况下,谱拟合方法可以用来研究激波前后的太阳风参数变化,本文用此方法对一例耀斑激波的单站观测结果进行了反演,计算表明,该激波在日心距为0.5AU处激波前太阳风速度为400km/s,激波后太阳风速度为600km/s。
If the compressed zone of a shock superpe on all or most of the principel scintillation zone in the line of sight of a radio source and so the change of scintil1ation index before and behind the shock would be large, the spectral fitting method maybe used to induce the velocity of so1ar wind. A single station IPS data was sampled and the result indicated that .the ve1ocity was 400km/s before this ishock and 600km/s after this shock.
