摘　　要：利用分离变量法,获得了广义Nizhnik Novikov Veselov方程的局域相干孤子解.考察了多Solitoff解和多孤子激发的相互作用,发现其相互碰撞是完全非弹性的.这些局域相干结构的相互作用存在裂变和聚变现象.By using the variable separation approach, we have obtained abundant localized coherent solutions for the (2+1)dimensional generalized NizhnikNovikovVeselov (GNNV) equation. We have studied the behaviors of the interactions for the multiSolitoff solutions and multiSolitonic excitations and found the interactions are completely nonelastic. The fissions (or fusions) of these localized coherent structures may occur after their interactions.
