摘要

我们研究了液体中高振幅共振孤子与相互运动的气泡的碰撞。这种相互作用具有非弹性性质。两个共振孤子完全合并状态的振幅是它们初始振幅的三倍。在相互作用过程中会发出两种强烈的声波前体。当孤子离开相互作用区域后，其中会出现一个空间有限的耦合气泡脉动区。这些过程降低了孤子的能量，使其永远无法恢复到原来的状态。

Inelastic Collision of Resonant Solitons in a Bubble Medium

We study a collision of high-amplitude resonant solitons in a liquid with gas bubbles moving towards each other. The interaction is of an inelastic nature. The amplitude of the state of full merging of two resonant solitons is three times their initial amplitudes. Two intense sonic precursors are emitted during the interaction. After the solitons leave the interaction region, a space-limited zone of coupled bubble pulsations arises in it. These processes reduce the energy of solitons, which never restore to their original state.
