摘 要: 简述了中子星结构、组成、演化的理论研究以及相关的观测进展,对演化后期孤立毫秒脉冲星和处于双星系统中的脉冲星可能存在夸克解禁和夸克重囚禁的现象进行了理论上和观测证据上的探讨。认为双星系统中的脉冲星可能会由于条件不同,会分别出现夸克解禁和夸克重囚禁的现象。 Theoretical research and observational progress on the structure, compositions and the evolution of neutron stars are briefly reviewed, then the theory and observational evidence of the deconfinement and recortfinement of quark matters in the old isolated millisecond pulsars and the pulsars in binaries are discussed. To the pulsars in binaries, as the conditions are different, both of the deconfinement and the reconfinement of quark matters may take place.
