It uses its claws to catch its prey, which is never bigger than the arachnid itself.

巨骆驼蜘蛛会用爪子捕获体型不及蜘蛛纲动物的猎物。

Predatory arachnid that usually has silk-spinning organs at the back end of the body; they spin silk to make cocoons for eggs or traps for prey.

食肉型蜘蛛类节肢动物，通常在身体尾部有一个吐丝器官；它们吐丝来结茧或结网以捕捉昆虫。

The Arapaima uses its bony tongue to crush prey against the roof of its mouth before swallowing.

在咽下去之前，巨骨舌鱼使用其带骨头的舌头将猎物与自己的上颚仿佛撞击。

De Blacas, I must change your armorial bearings; I will give you an eagle with outstretched wings, holding in its claws a prey which tries in vain to escape, and bearing this device--Tenax.

我让你猜一谜，有一只展开双翅的老鹰，它的脚爪抓住了一只猎物，这个猎物想逃跑，但又逃不了，它的名字就叫做――Tenax［拉丁文：固执］。

In Chapter 3, the asymptotic behavior of n-species nonlinear prey-competition systems is discussed.

在第三章中，我们讨论了n-种群非线性捕食—竞争系统的渐近行为。

We proposed and analyzed a class of Lesli predator-prey model with mutual interference and obtain global asymptotic stability of positive equilibrium point for the model by using the theory and method of stability.

建立并分析一类具有相互干扰的Leslit捕食与被捕食模型，运用稳定性理论及方法得到了该模型正平衡点的全局渐近稳定性。

This paper consists of three parts:We first consider the non-autonomous predator-prey system with both Beddirigton-DeAngelis functional response and dispersion. By using comparison theorem of differential equation, we study the permanance of the system. After that, by constructing suitable Lyapunov function, we obtain some sufficient condition which guarantee the existence of globally asymptotically stable almost periodic solution of the system.

本文研究三方面的内容：第一部分考虑具有扩散和Beddington—DeAngelis功能反应的捕食-食饵系统，利用微分方程比较原理得到该系统一致持续生存的条件；通过构造适当的Lyapunov函数得到了该系统存在全局渐近稳定概周期解的充分条件。

With the help of comparison theorem, sufficient conditions which guarantee permanence of the system are obtained. For the almost periodic case, by constructing a suitable Liapunov function, we obtained that the system has a unique globally asymptotically stable positive almost periodic solution. Finally, we study a multispecies predator-prey system with stage structure and Holling II type functional response.

第二部分考虑具有阶段结构的非自治扩散捕食系统，利用比较定理得到该系统持久生存的充分条件，其后在概周期情形下通过构造合适的Liapunov函数得到了保证该系统存在唯一一个全局渐近稳定的概周期解的条件。

This paper consists of three parts: Firstly, we discuss a nonautonomous -species two-patches cooperative Lotka-Volterra diffusion system. Using Brouwer fixed-point theory and Liapunov function, under some conditions, we obtain that the system has a unique globally asymptotically stable positive periodic solution. Secondly, we consider a kind of nonautonomous predator-prey model, in which preys are with stage structure and the predator are with two patches.

中文摘要：本文分三部分讨论三类生态模型周期解或概周期解的存在性及全局渐近稳定性等内容：第一部分讨论了两斑块种群的互惠Lotka-Volterra扩散系统，运用不动点理论和构造Liapunov函数，得到了系统存在唯一一个全局渐近稳定的正周期解的充分条件。

By using competitive adsorption of activated carbom to remove unfavorable influence of carbon in carbonaceous gold concentrate on leaching process, the leaching rate of gold concentrate can be improved to 88% as compared with 10%by direct cyanidation.

本文论述了利用活性炭竞争吸附作用，消除含炭金精矿中炭在浸出过程中的影响，使金精矿的浸出率可由直接氰化的10％提高到88％。
