第286行： − 在模型系统中，当猎物数量充足时，捕食者就会兴旺发达，但最终会超过食物供应量而减少。当捕食者数量较少时，猎物数量又会增加。这些动态在增长和衰退的循环中继续。+ 第585行：

In the model system, the predators thrive when there are plentiful prey but, ultimately, outstrip their food supply and decline. As the predator population is low, the prey population will increase again. These dynamics continue in a cycle of growth and decline.

在该模型系统中，捕食者在有大量猎物的情况下肆意成长，但最终它们会因为食物供应不足而下降。随即捕食者数量变低，猎物数量将再次增加。就此形成的动力结构以增长和下降的周期持续。
