摘要
针对多通道滤光器太阳磁场望远镜的磁场观测定标及掌握(所采用的)谱线特征之需要,取VAL宁静太阳大气模型计算了7条Fel光球线的Stokes轮廓、形成深度、贡献函数分布,从而较为系统地对多条反常及正常Zeeman线的特征及性质作出了分析与总结,解释了在磁光效应影响下Stokes Q,U参量的形成深度曲线在近线心区域处出现陡峭峰值的原因。
In order to meet the demand of the magnetic field observation calibration for the multichannel birefrigence filter, VAL quiet sun atmosphere model is adopted to compute Stokes profile, formation depth and distribution of contribution function for 7 Pel lines.The features and properties of some normal and anormalous Zeeman lines are analyzed, compared and summarized. The causes of sharp peaks of the Stokes Q and U curve under the influence of magnetic optical effect in the close line-center region are discussed.
