Under some weak assumptions on f, with the aid of some new analytical skills and Non-Nehari manifold method, we prove that (0.1) possesses one ground state sign-changing solution 616300663&_mathId=si7.gif&_user=111111111&_pii=S0022039616300663&_rdoc=1&_issn=00220396&md5=906d47e197e86b6da131b0b83a07970a" title="Click to view the MathML source">ub, and its energy is strictly larger than twice that of the ground state solutions of Nehari-type.
