| 摘 要： | With Hirota＇s bilinear direct method, we study the special coupled KdV system to obtain its new soliton solutions. Then we further discuss soliton evolution, corresponding structures, and interesting interactive phenomena in detail with plot. As a result, we find that after the interaction, the solitons make elastic collision and there are no exchanges of their physical quantities including energy, velocity and shape except the phase shift.

| Abstract: | With Hirota's bilinear direct method, we study the special coupled
KdV system to obtain its new soliton solutions. Then we further
discuss soliton evolution, corresponding structures, and
interesting interactive phenomena in detail with plot. As a
result, we find that after the interaction, the solitons make
elastic collision and there are no exchanges of their
physical quantities including energy, velocity and shape except the phase shift. |
