| 摘 要： | 研究和详细地比较了RMF理论中不同的有效相互作用强度的密度依赖性， 并且讨论了这种密度依赖性对于核物质和中子星性质的影响. 对于核物质， 不同的参数组给出的对称核物质的饱和点非常接近， 基本都在经验值的范围内. 对于中子星， 考虑超子后不同参数组给出的质量极限的范围为1.52—2.06 M☉， 半径为10.24—11.38 km.The density dependencies of various effective interaction strengths in the relativistic mean field and their influences on the properties of nuclear matter and neutron stars are studied and carefully compared. The differences of saturation properties given by various effective interactions are subtle in symmetric nuclear matter. The Oppenheimer Volkoff mass limits of neutron stars calculated from different equations of state are 1.52—2.06 M☉, and the radii are 10.24—11.38 km with hyperons included.

| Abstract: | The density dependencies of various effective interaction strengths in the relativistic mean field and their influences on the properties of nuclear matter and neutron stars are studied and carefully compared. The differences of saturation properties given by various effective interactions are subtle in symmetric nuclear matter. The Oppenheimer-Volkoff mass limits of neutron stars calculated from different equations of state are 1.52-2.06 M☉, and the radii are 10.24-11.38 km with hyperons included. |
