摘要：

We present results from the first systematic survey of the near-infrared (1-2.5 mum) spectra of cataclysmic variables. Emission lines of H I and He I are present in most objects. He II emission is observed in V Sge. Lines from high-ionization species may be present in TT Ari and SS Cyg. Absorption features typical of late-type stars are detected in some systems. Spectra of SS Cyg over several years show possible variability of the absorption line strengths. On some occasions the absorption lines in SS Cyg may be stronger than those expected from a K5 V star.
