关键词: The shell corrections and shell gaps in nuclei are systematically studied with the latest Weizsacker-Skyrme ;  (WS4) mass model. We find that most of asymmetric nuclei with (sub) shell closures locate along the shell stability ;  line (SSL) ;  N=1.37Z+13.5 ;  which might be due to a strong correlation between neutrons and protons near ;  the Fermi surface. The double magicity of nuclei Si-46 and Ni-78 is predicted according to the corresponding ;  shell gaps ;  shell corrections ;  and nuclear deformations. The unmeasured superheavy nuclei ;  (296)118 and (298)120 ;  with relatively large shell gaps and shell corrections ;  also locate along the SSL ;  whereas the traditional magic ;  nucleus (298)F1 evidently deviates from the line. The alpha-decay energies of superheavy nuclei with Z=113-126 ;  are simultaneously investigated by using the WS4 model together with the radial basis function corrections. For ;  superheavy nuclei with large shell corrections ;  the smallest alpha-decay energy for elements Z=116 ;  117 ;  and 118 ;  in their isotope chains locates at N=178 rather than 184.
