太阳宁静区网络磁场和速度场结构的空间分布谱和滤波分析

THE SPACE DISTRIBUTION AND FILTERING ANALYSIS OF MAGNETIC AND VELOCITY FIELDS OF SOLAR QUIET REGION NETWORKS

本文对1988年9月7日连续观测的太阳大气宁静区的光球磁场和速度场以及相应区域的色球速度场,进行了空间分布谱和滤波分析,并着重讨论了磁场和速度场的各种空间尺度的分布情况,以及它们之间的相互关系.分析表明,不同层次速度场的特征尺度存在着差异;色球的物质运动图形与宁静光球磁场网络结构较为吻合;光球和色球均存在大于超米粒尺度的速度场结构,但其速度的幅值较小.

In this paper, we do the space distribution and filtering analysis to photosphere magnetic field, photosphere velocity field and chromosphere velocity field of same quiet region observed on Sep. 7, 1988. The distribution of different space size of magnetic and velocity field structures and the relationship of them are discussed. It shows that there is a difference between characteristic sizes of different layers; the flow of chromosphere matters and the magnetic networks of photosphere are coincident; in both photosphere and chromosphere exist flow structures on a larger scale than supergranules but with smaller speeds.
