摘要：
For a finite-length hydrogen-bonded chain, the soliton ferryboat model for the dc conductivity and the vibrator model for the ac conductivity are discussed. We show that the contact effect of the boundary will reduce the average speed and the mobility of the solitonic defects. When the motion of the solitonic defects keeps step completely with the periodic external electrical field, the contact energy at the boundary is zero.
