The time-evolution of quantum meson fields in O(4)-linear sigma model istreated approximately. It is shown that the amplification of the amplitudes ofpion modes with low momenta occurs by means of both the parametric resonanceand the forced oscillation.Comment: 8 pages, no figure, using PTPTeX styl
