Abstract: The entropy exchange between the field and atom in a Jaynes-Cummings model with a dissipation field are studied.The results show that there is an entropy correlation phenomenon between atom and field.Especially we proved that there exists a condition for entropy exchange between atom and field.At the same time, the con-currence between the atom and the dissipation field is calculated.The relationship of entropy change and entan-glement between two subsystems is found.
