摘　　要：本文综述了中子星内部可能的退禁闭相变以及相结构和相变行为对中子星演化的影响.通过分析两化学势核物质相平衡条件下的解,指出中子星中可能存在混合强子-夸克物质相.讨论非静态中子星的r-模引力波辐射和热辐射,从中子星动力学过程探讨夸克物质存在于中子星内部可能的信号.Possible deconfinement phase transitions in neutron stars and the influence of phase structure and phase transition behavior on their evolution are reviewed in this paper.Possible existence of the mixed hadron-quark phase was studied by analyzing a solution of the phase equilibrium of the nuclear matter system with two chemical potentials.The r-mode gravitational wave instability radiation and the thermal radiation of non-equilibrium neutron stars are discussed,and possible signals of the existence of quark matter inside neutron stars were investigated from the aspect of the dynamic process of neutron stars.
