摘要In the GCM we study some properties of pi meson as the Goldstone bosons in a nuclear matter with finite density. Using the effective action in a nuclear matter, we calculate the decay constant and pi mass as functions of the chemical potential. The relation between the chemical potential and the density of a nuclear matter is firstly given here. We find that f(pi) and m(pi) monotonously decrease as nuclear matter density increases. The result is consistent with the usual assumption that the chiral symmetry is gradually restored as the density of a nuclear matter increases.
