Abstract：
A new method for the relativistic calculations of particle hole and delta-hole excitations of pious in nuclear matter is given.We point out the difference between the usual methods and ours.The dispersion relation of the pion meson including virtual particle-hole excitation is calculated and compared numerically with that of the non-relativistic case.The formulae of relativistic delta-hole excitation of pious in nuclear matter are also given.
