摘要
Based on the recent QSO surveys it is shown that, contrary to the widespread notion, high-luminousity QSOs are at least as numerous in the nearby universe as the ultraluminous far-infrared galaxies (ULIGs). Therefore, the fraction of ULIGs that have got a hidden quasar at the nucleus, for example in the dust shrouded phase, cannot be overwhelmingly large.
