| 摘 要： | 利用Nambu|Jona|Lasinio(NJL)模型描述奇异夸克物质, 并研究奇异夸克物质及奇异星的性质. 通过求解能隙方程, 给出了组分夸克的动力学质量和数密度随重子数密度的变化关系; 计算得到奇异物质的状态方程及奇异星的质量|半径关系. 结果表明, 用NJL模型描述的奇异星质量和半径均较小, 并在观测值的下限附近. |
| 关 键 词： | 奇异星 状态方程 质量 半径关系 |

| Abstract: | The properties of strange quark matter and strange stars were studied by means of Nambu-Jona-Lasinio(NJL) model to describe the strange quark matter.Dynamical mass and number density of consisent quarks versus baryon number density were given by means of solving the gap-equations.The equations of states for strange quark matter and corresponding mass-radius relation of strange star were also investigated.The numerical results show that the mass and radius of the strange stars described by NJL model are smaller than that of EMBM within the scope of observational data. |
| Keywords: | strange stars equations of state mass-radius relation |
