讨论了中子星星在绝对零度下的性质。确定中子星星基态的问题是制定在一般的方式和条件下，人们可能会合理地希望，一个单独的粒子模型（我们采用）是有效的。强相互作用对各种强子的数密度和产生阈值的影响用几个例子来说明。利用核物质理论中的有效质量近似，计算了中子星星中中子和质子能谱的修正。除了核子以外，强子对物态方程和比热的贡献也作了粗略的估计。
The properties of a neutron star at absolute zero temperature are discussed. The problem of determining the ground state of a neutron star is formulated in a general way and the conditions are described under which one might reasonably hope that an individual-particle model (which we adopt) is valid. The effects of the strong interactions on the number densities and production thresholds of the various hadrons are illustrated with several examples. The modification of the energy spectrum of neutrons and protons in a neutron star is calculated using an effective-mass approximation adapted from the theory of nuclear matter. Crude estimates are made of the contributions of hadrons other than nucleons to the equation of state and specific heat.
