solitons motion in some external potentials. The focus is the solitons with zero initial
velocity，which exhibit different behaviors in po- tential wells and barriers，and the results are
that the barrier repels solitons and the potential well attracts solitons. These conclusions are
verified by numerical simulation.
Key words： Bose-Einstein condensate; soliton; Lagrangian
