四米长的海蝎子，十尺长并长有狗状头骨的哺乳动物，还有如人类头般大的巨型蜘蛛，以上提到的并非是在恶梦才会见到的生物，而是在恐龙出现前，曾经占领地球中的几种动物。

Diffusion problem of a predator-prey model with Holling typeⅡfunctional capturing function is studied. Stability condition is obtained when diffusion is absent, and the effect on stability of positive equilibrium is studied when diffusion is present. In the end, the problem of existence of limit cycle is proved in the first quadrant when diffusion is absent.

针对一类具有HollingⅡ型功能捕获函数的捕食－食饵模型的扩散问题进行了研究，得到了无扩散时正平衡点的稳定条件，以及扩散存在时对正平衡点稳定性产生的影响，最后证明了无扩散时系统在第一象限存在极限环的问题。

A: The flintlock pistol from Predator 2 was inscribed Raphael Adolini 1715, thus proving that either Yautja are very long-lifed creatures, or just that their clans have been hunting on Earth for hundreds of years.

答：那把燧石手枪上面记着"Raphael Adolini 1715"，证明 Yautja 是一种寿命很长的生物，并且已经在地球上狩猎了数百年，根据"XXX"这把手枪是一个Yautja在1718年猎杀一帮海盗时获得的奖品。

Predator: The unmanned plane is in high demand in Iraq and Afghanistan because it provides full-motion video of a battle zone in near real time.

捕食者：伊拉克和阿富汗急需无人驾驶飞机，因为它能提供近乎实时的战区全面动态视频。

Predator-prey models ; Functional response ; Constant rate stocking ; Limit cycle

1模型与平衡点分析考虑捕食者无密度制约，食饵具有非线性功能反应函数

In the last chapter,by means of coincidence degree theory,we consider the existence of positive periodic solution for a generalized discrete prey-predator system with delay and functional responses.

在解的优先估计过程之中，运用了分析的方法，从而使得条件的验证更具可行性。

The first chapter discusses the showness of geometric figure and equilibrium\'s asymptotically stable of mathematical model of predator-prey.

第一章利用分析技巧和霍维茨定理研究了捕食与被捕食种群的循环Hassall数学模型几何图形表达和平衡点的渐近稳定性问题。

Experience with other fisheries, such as the collapse of the cod population of the Grand Banks off Newfoundland in 1992, has shown that the dynamics of an ecosystem can change when a top predator is removed completely.

根据其他鱼类的经验，如1992年的纽芬兰大浅谈的鳕鱼数量骤减事件表明：顶层肉食者完全被移除可改变成个生态系统的活性。

Gray-Faced Buzzard-Eagle is under the category of CITES Appendix II and also listed as the Rare and Valuable Animal Species in Wildlife Conservation Act . Gray-Faced Buzzard-Eagle as the highest predator in the food chain is thus also ecologically significant.

灰面鵟鹰为《华盛顿公约》附录二物种，同时也是《野生动物保育法》列名的珍贵稀有野生动物，而且灰面鵟鹰是食物链中的最高猎食者，因此在生态系里具有特殊重要性。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
