Abstract
We make a systematic study of the chiral restoration transition in fun ction of the two free parameters of two scaled effective NJL Lagrangia ns. We show that it is not possible to reproduce with the same set of parameters the temperature behaviours of the quark condensate and of t he quark entropy and a critical density at least equal to the normal d ensity of nuclear systems.
