摘要：The conserving σ-ω-ρ mean-field approximation with nonlinear interactions of hadrons has been applied
to examine properties of nuclear matter and hyperonic neutron stars. The nonlinear interactions that will
produce density-dependent effective masses and coupling constants of hadrons are included in order to
examine density correlations among properties of nuclear matter and neutron stars such as binding energy,
incompressibility, K, symmetry energy, a4, hyperon-onset density, and maximum masses of neutron stars.
The conditions of conserving approximations in order to maintain thermodynamic consistency to an
approximation are essential for the analysis of density-dependent correlations.
