摘　　要：综述了脉冲星-黑洞（PSR－BH）系统的诞生率理论并指出近期发现该系统的可能性。通过综述和分析脉冲星-中子星（PSR－NS）系统的观测特性，特别是脉冲星精确守时性对精确确定双星轨道参量和验证引力理论的重要意义，推测了PSR－BH系统的可能性质，指出发现PSR-BH系统对黑洞的搜寻和最终证认的重要意义。最后简介目前搜寻PSR-BH系统的现状和我们搜寻短轨道周期脉冲双星的计划。Theories of the birthrate of the pulsar-black hole (PSR-BH) systems are reviewed. It is pointed out that at least one of such kind of systems is likely to be discovered recently. The observational characteristics of the pulsar - neutron star (PSR-NS) systems, especially the important impact of their accurate timing properties on the determination of orbital parameters of binary systems and the test of gravitational theories, are reviewed and analysed, which sheds light to the study of the unknown PSR-BH systems. It is argued that the discovery of the PSR-BH system is of great significance in the field of searching for and confirming the existence of black holes. Finally, current status of searching for PSR-BH systems and our plan on searching for short orbital-period binary pulsars are briefly introduced.
