本文用数值方法研究了活化剂-抑制剂型反应扩散系统中脉冲的碰撞和自复制问题。我们建立了脉冲动力学的以下新性质。两个传播脉冲在正面碰撞后产生局部振荡域。然而，这个域是一个瞬态域，在一个周期后消失，留下新的脉冲向外传播。在另一个参数范围内，一个行进脉冲分解成一对沿相反方向传播的脉冲。
We study numerically, the collision and self-replication of pulses in a reaction-diffusion system of the activator-inhibitor type. We established the following new properties of pulse dynamics. Two propagating pulses result in a localized oscillatory domain after a head-on collision. However this domain is a transient one and disappears after one period leaving new pulses propagating outward. In another parameter regime, a traveling pulse breaks into a pair of pulses propagating in opposite directions.
