Using non-equilibrium molecular dynamics and the Monte Carlo method, we simulated mass transport in a onedimensional channel with dynamic exteal potentials. This study focuses on the influence of the dynamic exteal potential field on the mass transport. Traveling wave and standing wave potential fields have been employed as our dynamic potential field. We found that mass transport can be promoted by the traveling wave field when the exteal potential moves along the direction of the mass current. When the standing wave field is exerted on the channel, the channel is found to work like a switch. The mass current can be "on" or "off" by adjusting the standing wave frequency. The effects of the period number, the amplitude and the velocity of the exteal potential on the mass transport are also discussed. Our research provides valuable advice for the control o particle transport through one-dimensional channels.
