摘要(Abstract): Blackhole X-ray binaries frequently exhibit quasi-periodic oscillations (QPOs) in their X-ray flux. Although these signals are strong and readily measurable, their physical origin has long remained elusive. Recent observational and theoretical advances, however, have significantly deepened our understanding. In this report, we first review the phenomenology of the various QPO classes observed in black-hole systems, with particular emphasis on low-frequency QPOs, where much of the recent progress has been made. We then introduce several key timing instruments-RXTE, XMM-Newton, and Chandra-and outline, in detail, the data-processing procedures employed for each. Finally, we discuss the scientific insights that these timing analyses can provide.
