| Abstract: | With the aid of a simple black hole model of quasars we have found that the majority of the distinguishable emission lines in the spectrum of the quasar 1604+179 can be assigned to two redshift systems,z
r
=3.712 andz
b
=2.701. The appearance of double emission redshifts means that this quasar might be a massive black hole (of mass 108
M
  M1011
M
) with a ring-like emission line region (of radius 1 light-day r
01 light-year) in its accretion disk. |
