The thermal evolution of nuclear matter at zero temperature and definite   baryon number density in chiral perturbation theory
  The thermal properties of cold dense nuclear matter are investigated with chiral perturbation theory.   The evolution curves for the baryon number density, baryon number susceptibility, pressure and the equation of state are obtained.   The chiral condensate is calculated and our result shows that when the baryon chemical potential goes beyond $1150 \mathrm{MeV}$, the absolute value of the quark condensate decreases rapidly, which indicates a tendency of chiral restoration.
