摘　　要：We investigate the entanglement in the interacting system of a single mode thermal field and a single qubit with dissipation in the dispersive limit. The influence of initial temperature of thermal field and atoms on the entanglement is then examined.We investigate the entanglement in the interacting system of a single mode thermal field and a single qubit with dissipation in the dispersive limit.
