非对称核物质状态方程是用来描写中子质子数不相等的核物质状态量,比如密度、同位旋不对称度与每核子能量之间的关系等。它对于理解很多核物理现象,如远离β稳定线的核结构、核反应及中子星的性质等都具有重要意义。大量的理论和实验研究表明,非对称核物质状态方程中的对称能部分还存在较大的不确定性。因此,如何确定对称能的密度依赖形式是目前核物理学家们关注的重要问题之一。到目前为止, Asymmetric nuclear matter equation of state is used to describe the number of neutron protons unequal nuclear state variables, such as density, isospin asymmetry and nuclear energy per nuclear relationship. It is of great importance for the understanding of many nuclear physics phenomena, such as the nuclear structure far away from the beta stable line, the nuclear reaction and the properties of neutron stars. A large number of theoretical and experimental studies have shown that there is still great uncertainty in the symmetric energy part of the asymmetric nuclear matter equation of state. Therefore, how to determine the density-dependent form of symmetry energy is one of the most important issues that nuclear physicists are currently concerned about. so far,
