This text utilizes the stability theory of differential equation, establishes the mathematical model of praying on the relation among the living beings, then according to the characteristic of differential equation group set up, through analyze to its equalization point,discuss the rail line distribution situation and overall stability, studies the dynamic change situation of every species during sufficient long time slot.

摘要本文利用微分方程稳定性理论，建立生物间捕食关系的数学模型，然后根据建立的微分方程组的特性，通过对其平衡点分析，轨线分布情况以及全局稳定性的讨论，研究出各物种在充分长时间段中的动态变化情况。

By comparison of the size, haunt, predator behavior and dietary habits, the Megalodon and the Timingila appear to be the same creature.

通过对比大小尺寸、游弋行踪、捕食者的行为以及饮食习性，Megalodon和Timingila都显示为是同一种生物。

How Much Nature Is Enough?Even some ardent conservationists acknowledge that the diversity of life on Earth cannot be fully sustained as human populations expand use more resources nudge the climate and move weedlike pests and predators from place to place.

连一些积极的自然资源保护论者都承认，随着人口的膨胀、消耗更多的自然资源、引起气候的变化，以及造成大量害虫和捕食动物的迁移等，地球上的生物多样性肯定不会完全地持续下去。

He points out that creatures are programmed to find food and to avoid predators.

这句的翻译应该是：他指出生物对其寻找食物和躲避捕食者的行为进行编程。

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.

随着邻体数目的增加，病毒的感染力度变得更大而且在空间上形成聚集的波形；(5)生境破坏及其空间结构在一定范围内有利于疾病的控制，这暗示人为对生境的干扰可作为疾病控制的一个潜在方法；(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播，生境破碎化程度越高(高丧失斑块的数量或低聚集程度)，将越有害于病毒的入侵和传播，这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程；(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内，宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势；(9)在捕食-食饵系统中，寄生感染病毒极有可能在生境破坏量较低时爆发；(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略；(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制，其中捕食者扮演共位捕食者的角色，已感染食饵作为共位食饵，易感染食饵扮作共同消耗的资源；(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的，这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

They hold great enmity for harpies, as the vile creatures like to capture young wyverns for food and to subvert and train as guardians.

它们对鹰身女妖怀有很大的敌意，因为这种邪恶的生物喜欢捕食年幼的双足飞龙，或暗使训练它们成为守卫。

As the vile creatures like to capture young wyverns for food and to subvert and train as guardians.

它们对鹰身女妖怀有很大的敌意，因为这种邪恶的生物喜欢捕食年幼的双

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
