Ananalytical solution of the master equation for two qubits-field system in
the dispersive reservoir are investigated, the qubits are initially in werner states. Under
the influence of the damping we investigate the quantum correlation in a two-qubit
based on measurement-induced disturbance (MID). We compare MID and entanglement
measured by negativity and illustrate their different characteristics. We find the
effect of damping on MID is weaker than negativity. Negativity will experience a
sudden transition but this will not happen for MID.
