摘　　要：The contribution of the resonant continuum to pairing correlations is properly treated in the relativistic mean-field （RMF） ＋ BCS approximation with a constant pairing strength. The single particle resonant states in the continuum are calculated by imposing proper scattering bound conditions. Introducing a level density in the continuum we studied the effect of the widths of single particle resonant states on the ground state properties. It is found that the proper treatment of the resonance continuum is important to the exotic nuclei near the drip lines. It could affect the pairing gap, Fermi energy,
