We have investigated the entangleable properties of two two-level atoms inside the dissipative cavity coupled to a single-mode radiation field under the big detuning, and discussed the influence of the initial state of the two atoms, the cavitity decay constant and the mean photon number on the entanglement degree. It have shown that if the two atoms are initially in the exicited or the ground states, they will be separate always; if the two atoms are initially in the coherent superposition of the excited and the ground states, the influence of cavity dissipation on the entanglement degree wil...
