使用Rossi X射线计时探测器对黑洞瞬变进行了16年的观测，加上其他X射线天文台和地面光学/红外/射电望远镜的补充，让我们清楚地看到了与其明亮爆发相关的复杂现象。这导致了少数光谱/计时状态的定义，这些状态由可观察到的显著跃迁分开。这些状态及其与相对论射电喷流射电辐射变化的关联完善了这一图景，并导致了吸积和抛射之间的联系的研究。许多基本问题仍然没有答案，但现有的图景为理论研究提供了一个很好的框架。我们讨论了目前的观测观点，重点讨论了爆发期间的光谱和时间演变，以及未来任务的前景，如ASTROSAT(2012)和LOFT(如果选择的话)。
Sixteen years of observations of black hole transients with the Rossi X-ray Timing Explorer, complemented by other X-ray observatories and ground-based optical/infrared/radio telescopes have given us a clear view of the complex phenomenology associated with their bright outbursts. This has led to the definition of a small number of spectral/timing states which are separated by marked transitions in observables. The association of these states and their transitions to changes in the radio emission from relativistic radio jets completes the picture and have led to the study of the connection between accretion and ejection. A good number of fundamental questions are still unanswered, but the existing picture provides a good framework on which to base theoretical studies. We discuss the current observational standpoint, with emphasis onto the spectral and timing evolution during outbursts, as well as the prospects for future missions such as ASTROSAT (2012) and LOFT (>2020 if selected).
