摘　　要：It is shown that SU（2） QCD admits an dual Abelian-Higgs phase, with a Higgs vacuum of a type-Ⅱ superconductor. This is done by using a connection decomposition for the gluon field and the random-direction approximation. Using a bag picture with soft wall, we presented a calculational procedure for the glueball energy based on the recent proof for wall-vortices [Nucl. Phys. B 741（2006）1].It is shown that SU（2） QCD admits an dual Abelian-Higgs phase, with a Higgs vacuum of a type-Ⅱ superconductor.
