摘要：In this paper we discuss the recent advances in the quantitative comparison of accretion, and the
accretion:jet coupling, in accreting black holes in both X-ray binaries (where MBH 10M ) and
Active Galactic Nuclei (105 MBH 109). These similarities include the radiative efciency
and jet power as a function of accretion rate, which are themselves probably the origin of the
`fundamental plane of black hole activity'. A second `fundamental plane' which connects mass,
accretion rate and timing properties provides us with a further physical diagnostic. Patterns of
radio loudness (i.e. jet production) as a function of luminosity and accretion state are shown to
be similar for X-ray binaries and AGN. Finally we discuss how neutron stars are a useful control
sample, and what the future may hold for this eld.
