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.
