摘要：

We construct the nuclear and quark matter equations of state at zero temperature in an effective quark theory (the Narnbu-Jona-Lasinio model), and discuss the phase transition between them. The nuclear matter equation of state is based on the quark-diquark description of the single nucleon, while the quark matter equation of state includes the effects of scalar diquark condensation (color superconductivity). The effect of diquark condensation on the phase transition is discussed in detail. (C) 2003 Elsevier Science B.V. All rights reserved.
