The theoretical analysis are verified by numerical simulations.Chapter 3 mainly considers a class of predator-prey model with sublinear functional response function. We deduce some sufficient conditions ensuring stability of equilibrium, nonexistence , existence as well as uniqueness of the limit cycle around the positive equilibrium.

第3章研究了一类食饵为线性密度制约，功能反应函数为次线性函数的食饵-捕食者模型，完整地对模型的平衡点的全局稳定性和极限环的存在惟一性进行了定性分析，得到了该系统不存在闭轨线，正平衡点全局稳定和存在惟一稳定的极限环的充分条件。

Through the simulate experiment, the studies on the eeffects of decomposition of the bait in a shrimp-pond on the water quality, changes of the water quality after the replacement of the seawater and after the removal of the remain bait coved the pond-bottom were done.

通过室内模拟实验，研究了虾塘底层残饵腐解对虾池水质的影响和更换虾池海水后底层水质质量的变化和清除覆盖于池底的残饵后池底底层水质的变化。

Don't use snail bait that contains metaldehyde, fly bait that contains methomyl, and mole or gopher bait where your dog or cat can get to it.

不要使用蜗牛的饵料，包含聚乙醛，飞饵包含灭，和摩尔或鼠饵所在狗或猫可以得到它。

Solenopsis invicta is definitely one of the most serious invaded species of the world. It has caused countless economic loss and public health risk. Unfortunately, it was found at Taiwan in 2003. The government purposes to eliminate S. invicta from Taiwan, and large amount of bait and contact insecticide has been applied in the field.

入侵红火蚁在其侵入地区造成了无以数计危害及经济损失，在防治上，以缓效性的饵剂为最节约的防治方式，尤其是对於建立初期，不易被发现的蚁巢，相对於接触性药剂，饵剂的灭蚁效果显得更为全面。

There are plastic baits that do but natural baits such as worms and flies make better.

有塑胶做饵，但天然饵虫和苍蝇等更好。

BassFan received TriggerX samples this week. They haven't been tested yet, but the baits look slick. They come in a clamshell package so each bait retains its shape while it marinates in the Ultrabite, and each bait style is ribbed to help increase the su**ce area and release more attractant.

TriggerX 系列产品外观润滑，每一条软饵都储藏在于其形状相同的独立容仓内，容仓包装设计坚硬，配以筋骨，不易被压变形，舱内存储密封液体 Ultrbite 浸液，软饵不但能长期保持形状，并可长期吸收信息素，保证饵料使用时的新鲜。

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。

It could test chain killing rate of cockroaches quickly using quadrate box, while simulating house could evaluate the chain killing efficacy against cockroaches externally.

结论方箱法能快速检验饵剂的连环杀蟑效果，模拟现场法能更客观的评价饵剂的连环杀蟑效果。

We formulate and study a predator-prey model with nonmonotonic functional response type and weak Allee effects on the prey.

本文主要对食饵上受到弱Allee效应作用的具有非单调功能反应的捕食-食饵系统进行研究。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
