查询词典 predator

When these parameters surpass a certain value, the system cannot appear the limitcycle. Through the various parameters\' changing, it demonstrates the forming process of the dissipative structure. Thus it show the dissipative structure\'s characteristic of the trophodynamics predation model and point out the ecological significance of the various parameters in the model.On the fourth chapter, the spruce aphides and its predator model is a predator model.

第四章，以两个捕食者作用于同一食饵的竞争关系模型为例，应用微分方程定性理论，对捕食模型中存在极限环的情况进行了讨论，用MATLAB在相平面上模拟出系统的极限环，此时该体系状态的发展呈现周期振荡趋势，从而揭示出营养动力学为基础的捕食模型耗散结构特征。

In Section 2.1, we construct a predator-prey system with stage structure on predator and impulsive per-turbations on prey,the predating products is used to increase the predators constitution.

在本章第一节中，构建了一个捕食者具阶段结构与食饵具脉冲扰动的时滞捕食-食饵系统，其中捕食者捕食食饵是为了增强体质。

In Section 2.2,we present a delay predator-prey system with stage structure on predator and impulsive perturbations on prey,the predating products is used to increase the predators ability of birth.

在本章第二节中，我们又构建了一个捕食者具阶段结构与食饵具脉冲扰动的捕食系统，其中捕食者捕食食饵是为了增强生育能力。

In this paper, we consider stage-structured predator-prey models with general functional response of predator and with prey using hawk and dove tactics.

本文主要考虑了捕食者具有一般性功能反应的阶段结构捕食模型以及阶段结构捕食模型中食饵采取鹰鸽对策的问题。

It should also be pointed out that the impact of the Allee effects of predator and prey due to different mechanisms on different predator-prey systems may also vary.

此外，引起Allee效应的机制不同，所考虑的系统不同，则Allee效应的影响也不一样。

The main conclusions in this paper are as follows:In this paper, I selected two classical models describing predator-prey systems and introduce the Allee effects into the dynamics of both the predator and prey populations in these models respectively.

通过数学分析和计算机模拟，我们可以看出，Allee效应可能是捕食者-猎物系统中的一个不稳定的因素。

In fact, in reallife, the prey species will be usually a?ected by the patchy environment, oncethe food in their patch is exhausted or there are abundant natural enemies intheir patch, they will leave in search for new habitats or refuges, at the sametime, the predator species also will be confined in a isolated patch, when thereis little food to feed on or the last prey is eaten the predators will depart andbecome predator dispersers.

事实上，在现实环境中食饵种群通常会受到斑块环境的影响，一旦在一个斑块上的食物吃完了或者存在太多天敌，它们会离开这个斑块寻找新的栖息地或避难所，同时捕食者种群同样会受到隔离斑块的影响，当在某个斑块上食饵种群稀少或吃完了最后一个猎物，捕食者种群将会离开变成迁徙者到其他栖息斑块上寻找猎物。

The predator will only hit you 4 in 100 times; And even then, it most likely WILL NOT be a vital organ

一百次中，只有四次歹徒会袭击逃跑的目标；即使他攻击你，大多不会是致命的部位，要跑！

The predator will only hit you 4 in 100 times; And even then, it most likely WILL NOT be a vital organ, RUN!

一百次中，只有四次歹徒会袭击逃跑的目标；即使他攻击你，大多不会是致命的部位，要跑！

The French are not suggesting a new EU treaty, but they have plenty of other wheezes.

法国人并不是在建议签署一个新的欧盟条约，但他们有许多其他的阴谋。
