生态学

I imagine there might be a world of mutating buildings, living silicon polymers, software programs evolving offline, adaptable cars, rooms stuffed with coevolutionary furniture, gnatbots for cleaning, manufactured biological viruses that cure your illnesses, neural jacks, cyborgian body parts, designer food crops, simulated personalities, and a vast ecology of computing devices in constant flux.

没准儿我们将面临一个世界，它变异建筑林立，活生生的硅聚合物肆虐，软件程序脱机进化，还有可变车辆、房间，里面塞满共同进化的家具，打扫卫生的蚊型机器人，批量生产的用以治病的生物病毒，神经外衣，生控体系统的身体部件，特制粮食作物，模拟个性，以及不断变化的巨型生态学的计算机装置。

Ecology is an interdisciplinary field which studies life and environment, human and nature, society and earth, spirit and material.

生态学是一门包容生命与环境，人类与自然，社会与地球，精神与物质的交叉学科。

Taking 6 evergreen avenue tree species including Magnolia grandiflora L.

63，从生态学和经济学角度看，这些行道树种选择比较合理。

Aerobes may be eliminated gradually after operation, and its likely to reach the normal state; the postoperative recovery of mucosa and mucociliary transport system seems to be a vital contributor for it. Two months maybe a transition during the repairing stage if systemaitcally postoperative cares engaged;5. Insights fro

在加强综合性术后处理基础上，两个月左右可能是一个转折点： 5、从微生态学角度出发，在慢性鼻窦炎中，全身性或局部抗微生物药物应用的必要性值得重新评价。

Both the Allee effect and the Allee-like effect are important for ecology and conservation.

不论局域种群的Allee效应还是集合种群的似Allee效应，对生态学的各个方面和保护生物学都有深刻的影响。

Allee effects have been much studied in ecology, reservation biology and biological invasion.

Allee效应是当前生态学、保护生物学和入侵生物学的研究热点之一。

Although there have been a great many papers on the Allee effect, they have mainly referred to only local populations and have not dealt with the relationship between the two and their impacts on the stability of ecological systems.

然而，虽然近年来关于Allee效应的研究文献非常多，但对于集合种群水平上的似Allee效应与局域种群水平上的Allee效应之间的关系，以及二者对生态学系统稳定性的影响的研究还相当缺乏。

However, most research has been focused on the Allee effects of local populations and both theoretical and experimental studies on Allee-like effects at the metapopulation level remain much too limited.

然而，目前的研究主要集中在局域种群水平上，关于集合种群水平上似Allee效应对生态学系统的影响，不论是理论还是实验研究都十分缺乏。

In the past tens of years, a lot of studies have been done to investigate the influences of Allee effects on population dynamcs, species interaction, conservation, species range expansion and alien species invasion.

近几十年来，人们开展了大量的理论和实验研究探索Allee效应对种群动态、种群间相互作用、生物保护、物种扩张和外来种入侵等生态学过程的影响。

In this paper, I have constructed models for local population and metapopulation dynamics. Then by mathematical analysis and numerical simulation, I focus my studies on the relation between the Allee-like effects at the metapopulation level and the Allee effects at the local population level and their impacts on the stability of ecological systems.

在本文中，通过建立局域种群和集合种群的理论模型，把局域种群动态和集合种群动态结合起来，用数学分析和数值模拟分析的方法研究了集合种群水平上的似Allee效应与局域种群的Allee效应之间的关系以及它们对生态学系统稳定性的影响，并对含Allee效应的物种的自然保护提供了理论依据。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
