对太阳质量为1.97\pm0.04 $的类中子星星的观测，对冷凝聚态物质的状态方程（EOS）给出了约束。本文考虑了用准粒子模型描述的纯夸克星星和含夸克核的混合星星的状态方程。影响夸克星星和混合星星质量的准粒子模型参数可以通过观测得到约束。
The observation of $1.97\pm0.04$ solar-mass neutron-like star gives constraint on the equation of state (EOS) of cold, condensed matter. In this paper, the EOS for both pure quark star and hybrid star with a quark core described by quasi-particle model are considered. The parameters of quasi-particle model which affect the mass of both quark star and hybrid star can be constrained by the observation.
