摘要
本文概述１９９１年７月１１日日全食时中国日食观测队在墨西哥ＬａＰａｚ所作的近红外光谱观测情况及得到的初步结果。观测是用一强光力望远镜和一中小色散的光谱仪，配以ＣＣＤ摄象机、图象处理器、微机等组成的探测系统进行的。日全食时，在λ１０７１２－１０９７２波区共摄得极上层光球和色球的无缝光谱４１帧。日面外约１．０９６Ｒ处的有缝光谱３５帧。文中还介绍了拍得的色球、日珥资料概况。
This paper briefly presents the preliminary results of the infrared spectroscopic observations made by the Chinese expedition during the 1991 July 11 total solar eclipse at La Paz, Mexico. The observations were carried out with a small focusratio telescope,a middle-low dispersion spectrograph and a detector system composed of a CCD camera,an image processor and a microprocessor.41 slitless spectra of the extremely upper photosphere and chromosphere as well as 35 slit spectra with the slit 1.096 R beyond the limb were obtained between 10712 and 10972.Some qualitative description and analyses of these chromospheric and prominence spectra are also given.
