The stability of entanglement of two atoms in a cavity is analyzed in this work. By studying the general Werner states, we clarify the role of Bell singlet state in the problem of suppression of disentanglement due to spontaneous emission. It is also shown explicitly that the final amount of entanglement depends on the initial ingredients of the Bell singlet state.
