查询词典 the food chain

Based on the food chain relationship between nutrition, autotrophy and detritus biomass, considering the complementarity of the nutrition which is caused by the animalcule decomposition of the propagation reliquiae, as well as its losing caused by physical therapies, we set up a model of zoology dynamics about the reciprocity of nutrition-autotrophy-detritus biomass, and analyze the dynamical stability of the model solution by using modern nonlinear theory.

基于营养盐、赤潮藻类、碎屑的生物量之间的食物链关系，考虑到由于海洋内微生物分解动植物遗体对营养盐的补充以及物理因素导致的流失，建立了营养盐－赤潮藻类－碎屑的生物量相互作用的耦合生态动力学模型。运用现代非线性动力学理论，对模型解的动力学稳定性进行了分析。

In the animal world, the predators and their preys battle for life or death within the food chain. As for us human beings, we have a lot more to do in many others fields. Therefore, the room for tolerance and courtesy is much larger. People can coexist in peace as long as no one challenges another's limit. Those who bestride others' life and infringe their interests will certainly be punished because they are not supposed to act like bullying beasts.

动物界主要是为了果腹而激战，人类因为有更多的事情要做所以活动的范围更广、目标更多，彼此容忍和谦让的空间就大很多，只要不是超越了底限都是可以和平共处的，而那些无故挑战他人底限的人便被绳之以法，因为他们无权拥有野兽那样的行动理由。

4以电子商务网站作为实例，来验证了模型的正确性，并给出了模型的应用方法。

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。

It is great news for long-suffering depositors who have been at the bottom of the food chain.

Although no longer used, dieldrin can persist in the environment for decades and move up through the food chain, particularly in dairy products and meats, to humans, Pennell said.

虽然不再使用，狄氏剂，可长期存在于环境中，几十年来，并提出了通过食物链中，特别是在乳制品和肉类，给人类， pennell说。

Pyramid of numbers A type of ecological pyramid in which the number of individual organisms at each stage in the food chain of the ecosystem is depicted diagrammatically.

数量金字塔：一种生态金字塔类型，其生态系统食物链中每个阶段的生物个体的数量用图表描述。

They are not watersoluble and float on the surface of water where they are eaten by aquatic animals and so enter the food chain.

So if the old theory that we die with the heart cells we are born with is true, then people born before carbon 14 got into the food chain (nuclear testing didn't start until 1955) wouldn't have any carbon 14 in their heart cells.

如果根据心肌细胞不可再生理论，那么在C14进入食物链之前（1955年核试验开始前）出生的人心肌细胞内不会有C14，但事实并非如此，这些人的心肌细胞不仅含有C14，研究者还测定出了C14存在体内的时间。
