基于非线性平均场模型,引入介子自能中的交换图修正,得到介子在介质中的有效质量随核物质密度的变化,且影响核子在介质中的有效质量以及高密核物质的状态方程,使得高密核物质的状态方程变软.

Based on the nonlinear mean field model,the contribution of the exchange diagram in the self-energy of mesons is introduced.This correction leads to the variation of the in-medi-um meson mass with respect to the nuclear matter density.It also modifies the in-medium nu-cleon masses and the properties of high density nuclear matter.The equation of state for high density nuclear matter is softe...
