Abstract：
Based on the nonlinear σ-ω-ρ mode in the relativistic mean fields approximation, we have obtained the relation between nuclear density r and the effective masses M*Θ+ of the pentaquark Θ+ by using the function of energy density. We investigated the parameter of the different models effects on the effective masses M*Θ+ of the pentaquark Θ+ in the nuclear density r. At the same time, we also try to study the couple coefficient ΓΘ/Baffect on the effective masses M*Θ+ in different parameters.
