Black hole X-ray binaries are two-body systems, which are quite active and always attract great attention from astronomer over last century. In this binary system, the primary object is believed to be stellar-mass black hole, while the companion star are thought to be normal stellar or white dwarf. The black hole and companion star orbit around each other, and the matter from the companion is accreted onto BH, releasing gravitational energy and radiate in multi-bands from optical to hard X-ray, even Gamma ray. Moreover, Such binary system are observed to undergo transition of the flux from quiescent state to burst state. In the burst state, the luminosity of the system in X-ray band is at least 1000 times brighter than our Sun's radiation. Studying black hole X-ray binaries system will help us not only test Einstein's general relativity theory, but also better understand the magneto-hydrodynamics (MHD) in the nature. In this presentation, I will mainly talk about the spectral and timing properties of black hole X-ray binaries.
