研究了二维可变形自推进粒子相互作用系统中的类孤子性质。通过改变形变的弛豫速率，数值研究了迁移速度随局部密度增加而增加的模型的碰撞动力学。在较大的弛豫速率下，带在迎面碰撞时是不稳定的。这清楚地表明，变形能力起着关键作用的孤子的行为。
We study the soliton-like character of traveling bands in systems of interacting deformable self-propelled particles in two dimensions. The collision dynamics of the model in which migration velocity increases with increasing local density is investigated numerically by changing the relaxation rate of deformations. The bands are unstable upon head-on collisions for larger relaxation rates. This clearly indicates that deformability plays a crucial role of the soliton-like behavior.
