  The nature of AXPs/SGRs (anomalous X-ray pulsars/soft $\gamma$-ray repeaters)
and high field radio pulsars is still unclear even in the magnetar and/or
accretion models. The detection of radio emission from AXP XTE J1810$-$197 and
the discovery of a debris disk around AXP 4U 0142+61 might shed light on the
problem. We propose that AXPs/SGRs could be pulsars that have magnetic field
$B\lesssim 10^{13} \mathrm{G}$ as normal pulsars, but in accretion
environments. We investigate these issues under the accretion model and find
that two of the AXPs/SGRs might be low mass quark stars if all AXPs and SGRs
are likely grouped together.
