论文摘要
核物质参数定义了状态的核方程（EOS），它们是在对称和不对称核物质饱和密度周围扩展的系数。我们回顾了它们与均事核和中子恒星在平均场框架内的几种特性的相关性。较低的核物质参数，例如每个核子的结合能，不可压缩性和对称能量系数，通过其与有限核的选择性特性的牢固联系在狭窄的限制下受到限制。从核物质参数与中子星可观察物的相关性中，我们进一步回顾了质量范围内中子星的半径和潮汐变形性的精确知识，$ 1-2 m_ \ odot $可能会帮助它们以较窄的范围施放。但是，较高的参数（例如密度斜率和对称能的曲率或对称核物质的偏度EOS EOS的偏斜度）困扰着更大的不确定性。从这些高阶核物质参数与较低阶的相互关系中，我们探讨了如何将它们带到更和谐的界限。
The nuclear matter parameters define the nuclear equation of state (EoS), they appear as coefficients of expansion around the saturation density of symmetric and asymmetric nuclear matter. We review their correlations with several properties of finite nuclei and of neutron stars within mean-field frameworks. The lower order nuclear matter parameters such as the binding energy per nucleon, incompressibility and the symmetry energy coefficients are found to be constrained in narrow limits through their strong ties with selective properties of finite nuclei. From the correlations of nuclear matter parameters with neutron star observables, we further review how precision knowledge of the radii and tidal deformability of neutron stars in the mass range $1 - 2 M_\odot$ may help cast them in narrower bounds. The higher order parameters such as the density slope and the curvature of the symmetry energy or the skewness of the symmetric nuclear matter EoS are, however, plagued with larger uncertainty. From inter-correlation of these higher order nuclear matter parameters with lower order ones, we explore how they can be brought to more harmonious bounds.
