摘要 (Abstract): 

Black hole X-ray binary systems (XRBs) are ideal sources to study the accretion process. In this talk, I will discuss how we can use the X-ray reflection component, namely the reprocessed coronal emission by the optically thick accretion disk, to study the evolution of the disk-corona system during the outburst of XRBs. One of the most important results is that the disk is found to be stable during the hard-to-soft transition. Accretion is always accompanied with outflows, which not only regulate the inflow but also contribute to feedback to the environment. I will also talk about disk wind outflows in XRBs.
