摘要：

We have obtained CCD spectra for 30 chromospherically active binaries using the 2.16 m telescope at Beijing Observatory in 1995. Our purpose was to search for the presence of H-alpha emission which is characteristic of stars with extreme levels of chromospheric activity. Spectra of V711 Tau, V471 Tau, HD 12545 and V833 Tau presented H alpha emission above the continuum in the different degree. The H alpha behavior of the other observed 26 active binaries, which were unknown in CABS (1993), has been discovered in this paper. The H alpha profiles of the most among 26 systems are partially filled-in by chromospheric emission. The H alpha profiles of a few systems show a pure absorption line. The results are given in Table I.
