  Bosonization of the strong interacting matter as a process of arising
observable hadrons is studied in terms of the phase transition of the second
kind. The spectrum of bosons which is free from the zero point energy is
derived . The calculated boson mass is found to depend self-consistently on
both the amplitude of a gauge field and quark mass. In the framework of the
quasi-classical model a hadron mass is calculated in the case of bosonization
into pions.
