Consequently, a prey-predator model with impulsive effect and the prey infected is established. In this model, the disease is controlled by the impulsive culling to the prey.
有时为了对传染病进行控制,常常在固定的时间点对有疾病的种群直接进行捕杀,以降低种群的密度,因此建立了一类具有脉冲效应且食饵有病的捕食与被捕食模型,该模型通过对食饵进行脉冲剔除对其进行疾病控制。

第三章讨论了一类具有阶段结构的捕食被捕食生态流行病模型，考虑了特定的功能反应函数和饱和传染率，得到了既有时滞因素又有脉冲效应的微分方程。
参考来源 - 具有时滞和脉冲的传染病模型与生态流行病模型的动力学研究There have been a fair amount of previous works on the standard Lotka - Volterra type prey-predator model (see 1-3),in which the mean predation rate was also assumed to be dependent on the density of the prey.
比如说，对于标准的Lotka-Volterra型捕食被捕食模型(参见1～3)，在这些模型中考虑的平均捕食率一般基于食饵种群的密度。

When experimental populations are set up under simple laboratory conditions, the predator often exterminates its prey and then becomes extinct itself, having nothing left to eat.
当实验种群在简单的实验室条件下建立起来时，捕食者往往会消灭它的猎物，然后自己也走向灭绝，因为没有东西可以吃。
The elements of intelligence and consciousness come together marvelously to produce different styles in predator and prey.
智慧和意识的元素奇妙地结合在一起，在捕食者和猎物身上产生了不同的风格。
Parasitism is a kind of predator-prey relationship in which one organism, the parasite, derives its food at the expense of its symbiotic associate, the host.
寄生是一种捕食者与被捕食者之间的关系，寄生者利用共生伙伴——宿主来获取食物。
