Abstract：
A model is proposed in which a meson considered as a collective vibrational stateconsisting of various quark-antiquark pairs. Whereas the quarks are quasi particlesundergone a superconductivity phase transition, there is a characteristic softeningphenomenon in the meson spectrum near the critical point of phase transition. Afterdiscussing the meson states with isospin I=0 (spin S=0,1) and I=1,(S=0) re-specticely, it is argued that phase transition occured all of them.
