太阳磁场的红外研究

THE STUDY OF SOLAR MAGNETIC FIELDS IN INFRARED SPECTRAL REGION

在简短的引言之后,本文首先叙述在红外波段观测太阳磁场的优越性,然后依次描述用He I10830A、FeI 1.5μ和Mg112μ等红外磁敏线的观测、资料及分析方法。这些谱线分别在色球层、光球最深层和光球上层形成,因此用它们可以探测太阳大气中很大范围的磁场。接着以磁元和黑子磁场为例,介绍现有的主要研究成果。结束语对我国的红外太阳磁场研究提出一些建议。

After a short introduction this paper at first describes the merits of observation of solar magnetic fields in the infrared wavelength region and,then.narrates successively the observations,data and methods of analysis in infrared magneto-sensitive spectral lines,such as HeI 10830A ?FeI 1.5μand MgI 12μ These lines are formed,respectively,in the chromosphere as well as in the deepest and the upper layers of the photosphere.Therefore,they can be used to probe the magnetic fields in a large range of height in the solar atmosphere.Thereafter,we introduce the main achieve ments with magnetic elements and sunspot magnetic fields as examples.In the conclusion some suggestions are proposed for the infrared study of solar magnetic fields in our country.
