摘要：

Preliminary results of high-resolution optical spectral analysis of two carbon-rich long-term variables, V1983 Cyg and V2047 Cyg, are presented. The stars were suspected to be cool R CrB variables according to their photometric light curves, although our spectroscopic study suggests that both stars are more similar to ordinary N-type carbon stars. For V1983 Cyg, possible absorption in the Balmer lines is detected.
