    摘要: Low-resolution spectrometer (LRS) spectra of 152 IRAS CCGCS1 sources with 12-mum fluxes of between 5 and 10 Jy are presented. This is part of an effort to extract spectra from the LRS 'raw data base' to search for more carbon stars with silicate emission features. The new spectra have been examined by eye and divided into six groups based on the classification scheme of Volk & Cohen. Four new carbon stars with silicate emission features (00519 + 5817, 19451 + 2856, 19583 - 0730 and 20092 + 3557) are found. The LRS spectra of three other carbon stars (08035 - 3837, 09083 - 5158 and 13182 - 6510) probably also contain silicate emission features.
