摘　　要：研究了两个方向相反的孤立子的碰撞问题,并将固壁反射看成是振幅相等的情况,由此得到了固壁反射时时间滞后的精确解,跟数值结果吻合得很好。The interaction between two solitary waves moving in opposite directions is discussed. The solitary wave remains its initial shape, amplitude and propagating velocity after the interaction, but has a phase delay or time delay. This time delay is obtained. The reflection of one soliton in Toda lattice can be considered as the interaction of two solitons which have same amplitude and moving in opposite directions. The time delay after one--soliton reflection is also obtained.
