摘要：

The QCD-motivated NJL model with gluon condensate is studied at finite temperature and baryon number density. We investigate the behavior of the constituent quark mass, quark condensate, meson masses, F(pi) and the coupling constants g(piqqBAR), g(sigmaqqBAR) as a function of temperature T. It is shown that the gluon condensate plays a stabilizing role for the behavior of different physical quantities when temperature changes.
