| Abstract: | 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. |
