关于微类星体的部分最新研究结果

对microquaLsar(微类星体)最新的一些研究结果作了比较全面的评述。具有相对论性喷流的microquaLsar在很多现象上类似于极小尺度上的类星体。对X波段的观测可以探测到吸积盘内区甚至接近黑洞的区域。结合低波段上的观测和研究，人们在吸积盘的动力学模型、物质吸积与喷流形成之间的关系以及喷流的超光速运动等方面的认识都有了长足的进步，并且发现了黑洞存在的新证据。对它们的研究为更好地理解河外天体的相对论性喷流和黑洞吸积方面的问题开辟了一条新的途径。

On Studies of Some Latest Results on Microquasar

Some latest studies on microquasars are comprehensively reviewed. Microquasars with relativistic jets mimic, on a much smaller scale, many of the phenomena seen in quasars. The X-ray emission from these objects probes the inner accretion disk and immediate surroundings of the black hole. Along with observations at lower frequencies, a great progress has been made in research fields such as the dynamical model of accretion disk, the connection between accretion of matter onto black holes and the origin of relativistic jets as well as the superluminal motion of jets. New evidences on the existence of black holes are also found in microquasars. Their studies open the way for a better understanding of relativistic jets and accretion of matter onto black holes seen elsewhere in the universe .
