Abstract：
The shell closure and shell anomalies of Mg, Si and S isotopes are investigated in the framework of relativistic mean-field theory. From two-proton and two-neutron separation gaps, we find that (1) there exist obvious shell effects at N=12, 16 in Mg isotopes, at N=14 in Si isotopes, and at N=16 in S isotopes, (2) the shell structure of Si isotopes at N=28 does not disappear, (3) the shell effects of Mg, Si and S isotopes at 20 are not very obvious.
