| 摘 要： | Variable separation approach is introduced to solve the （2＋1）-dimensional KdV equation. A series of variable separation solutions is derived with arbitrary functions in system. We present a new soliton excitation model （24）. Based on this excitation, new soliton structures such as the multi-lump soliton and periodic soliton are revealed by selecting the arbitrary function appropriately.

| Abstract: | Variable separation approach is introduced to solve
the (2+1)-dimensional KdV equation. A series of variable separation
solutions is derived with arbitrary functions in system. We present
a new soliton excitation model (24). Based on this excitation,
new soliton structures such as the multi-lump soliton and periodic
soliton are revealed by selecting the arbitrary
function appropriately. |
