摘要：
We present preliminary results of a neutral hydrogen (HI) redshift survey to find Low Surface Brightness (LSB) galaxies in the very nearby universe. Our sample consists of all galaxies in the APM catalog (Maddox et al. 1990) with a mean surface brightness of mu greater than or equal to 24 mag/arcsec(2), down to a magnitude limit of b(j) less than or equal to 17. With the Parkes 64m radiotelescope 35 objects were detected at nu < 4300 km s(-1). The resulting luminosity function, HI mass function, and for the first time total mass function are presented. It is found that LSBs make a negligible contribution to the overall integrated luminosity, HI mass, and total mass contained in galaxies.
