摘要：

All stars in the General Catalogue of Cool Galactic Carbon Stars with IRAS 12 mum fluxes greater than 5 Jy were searched for low resolution spectra (LRS) in the IRAS LRS database. Four more candidates for carbon stars with silicate features are found, bringing the total of this group of objects to 15. The spectral energy distributions of these 15 stars are fitted with a detached shell model, and the results are found to be consistent with the hypothesis that these stars represent transition objects between oxygen-rich and carbon-rich stars.
