摘要：

All stars in the General Catalogue of Cool Galactic Carbon Stars with IRAS 12-mu-m fluxes greater than 10 Jy were searched for LRS spectra in the IRAS LRS data base. Out of the 532 spectra examined, 11 were found to show the 9.7-mu-m silicate emission feature. Four of these are identified for the first time. This group of carbon stars may represent transition objects between oxygen-rich and carbon-rich stars on the asymptotic giant branch.
