| 英文摘要 | The present paper describes a two-dimensional multi-band spectrograph which is located at Yunnan Observatory (25-degrees-N 103-degrees-E), Kunming. The instrument consists of a coelostat system with an aperture of 40 cm, and spatial resolution better than 1'' under excellent seeing, and a spectrograph equipped with a plane reflecting grating. It can simultaneously obtain spectral data in ten bands, including the Balmer lines, metallic lines [Fe I lambda6173 angstrom, D1,2,3, Mg, and Ca II (H + K)] and He II lambda4686 angstrom. We are able to control the observational processes by means of a computer and obtain the following data synchronously or quasi-synchronously: multi-band spectra, Halpha filtergrams, magnetic field, and white light. With the aid of Halpha slit-jaw filtergrams, we can determine where and when the spectral data are obtained and, on the basis of analysing the spectral line profiles, we can understand the physical characteristics of an active region and derive the fields of physical parameters. For the line-of-sight velocities, the values measured are as high as hundreds of kilometers per second and as low as a few kilometers per second. |
