摘要：
From the LRS spectra of almost 2000 IRAS sources showing the 1612 MHz OH emission we found 9 candidates for OH/IR stars with SiC features in their envelopes. Further study indicates that 6 of these are definitely or very probably carbon star with the 11.3 mu m SiC emission feature in addition of being OH/IR stars showing the 1612 MHz OH maser emission.
