Abstract：
The density dependent relativistic hadron field theory(DDRH) containing meson δ is applied to very asymmetric nuclear matter. Because of the interaction between the nucleons and the scalar-isovector meson δ,the property of the asymmetric nuclear matter is so different from symmetric nuclear matter.The relations between scale density ρ_S and vector density ρ_B have been calculated. We also investigate the effective masses of nucleons in symmetric and asymmetric nuclear matter by using DDRH.The density dependence of in-medium kaon and antikaon effective masses has been obtained and then the effects of both the density dependence of the coupling constant Γ_i(ρ)(i=σ,ω,δ,ρ) and the scalar-isovector meson δ were discussed.
