Abstract: By the method of multiple scales,we have investigated the behavior of waves in a hydrogen-bonded chain with symmetric double-well potentials under damping  and found that the amplitude of the lattice waves decreases and the group velocity becomes slow under the action of damping.At the same time,we have derived the Damped NLS Equation and obtained its analytical solution.The results show that:there exists propagating dark envelope soliton in the hydrogen-bonded chain with symmetric double-well potentials under the damping.

Key words: damping, method of multiple scales, dark envelope soliton
