结果表明，一个外部的交流场可以支持稳定传播的孤子和椭圆余弦波的相互作用的粒子链中存在的摩擦，只要驱动振幅超过一定的阈值。的效果进行了分析的一般形式，然后被认为是详细的户田晶格与弱摩擦和任意摩擦的硬珠串。这种效应在连续极限中消失。
It is demonstrated that an external ac field may support stable propagation of solitons and cnoidal waves in a chain of interacting particles in the presence of friction, provided that the drive amplitude exceeds a certain threshold value. The effect is analyzed in the general form, and is then considered in detail both for the Toda lattice with weak friction and for a string of hard beads with arbitrary friction. The effects disappears in the continuum limit.
