本文从理论上和数值上研究了有限势垒非对称势阱中孤子运动的动力学。当阱宽、势垒宽和势垒高较大时，孤子表现为经典的孤子行为。另一方面，我们得到了具有亚势垒动能的孤子隧穿存在的条件。我们将这些结果应用于无序系统中孤子传输的研究。
We investigate (theoretically and numerically) the dynamics of a soliton moving in an asymmetrical potential well with a finite barrier. For large values of the width of the well, the width of the barrier, and/or the height of the barrier, the soliton behaves classically. On the other hand, we obtain the conditions for the existence of soliton tunneling with sub-barrier kinetic energies. We apply these results to the study of soliton propagation in disordered systems.
