摘要：

As the chirally restored phase ends with T coming down to T-c a phase resembling a mixed phase is realized, during which the hadrons (which are massless at T-c in the chiral limit) get their masses back out of their kinetic energy. The gluon condensation energy is fed into the system to keep the temperature (nearly) constant. Lattice results for the gluon condensation are matched by a Nambu-Jona-Lasinio calculation. The latter shows that below Tc the chiral symmetry is barely broken, so that with an similar to6% drop in the scalar coupling G it is restored at T-c. Nearly half of the glue, which we call epoxy, is not melted at T-c. (C) 2003 Elsevier B.V. All rights reserved.
