  We studied the long-term evolution of the spectral-temporal correlated
properties of the black hole candidate Swift J1753.5-0127 from the onset of its
outburst until 2011 with the Rossi X-ray Timing Explorer (RXTE). The source
stayed most of its lifetime during hard state, with occasionally transitioned
to the hard intermediate state. Similar to typical black hole transients, Swift
J1753.5-0127 traces a clear hard line in absolute rms - intensity diagram
during the low hard state, with expected highest absolute rms, while shows a
clear turn during the hard intermediate state, accompanied by lower absolute
rms. Different from Cyg X-1, we found that frequency-dependent time lag
increased significantly in the 0.02 -- 3.2 Hz band during state transition in
this source. The X-ray time lags in 0.02 -- 3.2 Hz can therefore be used as
indicators of state transition in this source. Type-C QPO frequency is
positively related with its fractional rms and X-ray photon index, suggesting a
moving inwards disk/corona scenario. We discussed the physical interpretation
of our results in our paper.
