| Abstract: | The periodicity of the dynamical evolution and the exact expressions of the pure states of the atom and the field are investigated in the two-photon Jaynes-Cummings model for the large initial field(n >>1) and the varied initial atomic states,which are examined by the distance between density operators. |

| Keywords: | Effect of atomic coherence Pure state Distance between density operators |
