摘　　要：太阳光谱的观测与研究能够得到太阳大气中与观测谱线对应层次的等离子体物质的视向速度、温度、密度等物理参数,不同波段的光谱对应太阳大气的不同层次、多个波段太阳光谱的同步观测,对太阳大气模型的建立和对已有模型的验证有重要意义。紫金山天文台多通道近红外太阳光谱仪,在三个波段,即Hα(6563A)、CaII 8542A和HeI 10830A,同时对太阳及其活动现象进行光谱观测,并获得缝前的Hα单色像。通过该光谱仪的观测,我们可以得到三条谱线的中心、线翼及附近连续谱的强度、谱线轮廓、速度等信息。目前已积累了从2001年到现在的Hα、CaII 8542Å和HeI 10830Å三个波段的光谱数据和光谱仪缝前Hα单色像数据。The observation and study of solar spectrum can help us to know the physical parameters,such as the plasma velocity,electron temperatures,electron density,etc.,of the line formation layers of solar atmosphere,because different spectral lines are formed in different layers of the solar atmosphere.Simultaneous observations in multiple lines are important for us to establish and testify atmospheric models.The Multi-channel Infrared Solar Spectrograph(MISS)at Purple Mountain Observatory records slit-jaw Hαmonochromatic images and obtains spectral data in the three spectral lines,namely,the Hα(6563A)line,the CaII 8542A line and the HeI 10830A line.From MISS observation data,we can get information about the intensity at the line center,line wings and nearby continuum of the three lines,as well as line profiles and plasma velocity.We have collected the observation data of MISS in the period from 2001 up to now.
