Abstract: The Markovian approximation of quantum dissipation has been reconsidered in the model of Caldeira and Leggett [Physica A 121 (1983) 587]. Their high temperature master equation has been generalized to medium temperatures. Two additional damping terms in the master equation have been derived and shown to assure the Lindblad form of the equation. A transient term in the density matrix has been found and expressed in a simple form.
