On the jet properties of the gamma-ray loud active galactic nuclei
  Based on broadband spectral energy distribution (SEDs), we estimate the jet
physical parameters of 1392 $\gamma$-ray-loud active galactic nuclei (AGNs),
the largest sample so far. The (SED) jet power and magnetization parameter are
derived for these AGNs. Out of these sources, the accretion disk luminosity of
232 sources and (extended) kinetic jet powers of 159 sources are compiled from
archived papers. We find the following, (1) Flat-spectrum radio quasars (FSRQs)
and BL Lacs are well separated by $\Gamma=-0.127\log L_{\gamma}+8.18$, in
$\gamma$-ray luminosity versus photon index plane with a success rate of
88.6\%. (2) Most FSRQs present a (SED) jet power larger than the accretion
power, which suggests that the relativistic jet-launching mechanism is
dominated by the Blandford-Znajek process. This result confirms previous
findings. (3) There is asignificant anticorrelation between jet magnetization
and a ratio of the (SED) jet power to the (extended) kinetic jet power, which,
for the first time, provides supporting evidence for the jet energy
transportation theory: a high-magnetization jet may be more easily to transport
energy to a large scale than a low-magnetization jet.
