  The non-topological FL model is studied at finite temperature and density.
The soliton solutions of the FL model in deconfinement phase transition are
solved and thoroughly discussed for different boundary conditions. We indicate
that the solitons before and after the deconfinement have different physical
meanings: the soliton before deconfinement represents hadron, while the soliton
after the deconfinement represents the bound state of quarks which leads to a
sQGP phase. The corresponding phase diagram is given.
