英文摘要We present preliminary results of near infrared observations of 6 S type symbiotic binaries, made with the aim of confirming and improving previous spectral classifications of the cool component. Representative CCD spectra of some symbiotic and comparison stars in the region of the Ca II infrared triplet are displayed. On our spectrograms at a dispersion of 33 angstrom/ mm the FeI/Ti II blend at 8469 angstrom and the Fe I line at 8514 angstrom are more useful luminosity discriminants for symbiotics than the Ca II triplet (8498, 8542 and 8662 angstrom) which is disturbed in some symbiotic spectra by emission components of the Ca II triplet and of Paschen lines. The temperature classification of late M cool components can be reliably derived from strengths of TiO and VO bands. Preliminary new spectral types and luminosity classes of six observed symbiotic stars are described and discussed.
