摘　　要：中子星致密物质的状态方程具有核天体物理、天体物理、致密QCD相结构等多方面的重要研究意义,对星体的结构、形成和演化等起决定作用。LIGO实现引力波直接探测更是开启了中子星研究的黄金时代。本工作介绍结合核物理和天文对中子星奇异相变、超子疑难、温度和频率演化等方面的研究进展,也将基于目前的多信使观测和状态方程微观参数的模型计算简述区分不同类型中子星的可能方法。The equation of state of dense matter in neutron stars holds significant research significance in nuclear astrophysics,astrophysics,and dense QCD phase structure.It plays a decisive role in the structure,formation,and evolution of these stars.The direct detection of gravitational waves by LIGO has ushered in a golden age of neutron star research.This article presents our research progress on neutron star strangeness phase transitions,hyperon puzzle,and the evolution of temperature and frequency.We combine nuclear physics and astronomy to analyze these phenomena and also discuss ways of distinguishing different types of neutron stars based on current multi-messenger observations and model calculations of microscopic parameters in the equation of state.
