环境论

This guide to effortless environmentalism is based on two assumptions o:p

不费力的环境保护论基于两种假设

This course introduces the information theory , which employs probability and ergodic theory to study the statistical characteristics of data and communication systems, and the coding theory , which uses mainly algebraic and geometric tools to contrive efficient codes for various situations.

本课程讲授信息论和编码的基本理论。信息论采用概率论和遍历理论的方法研究数据和通信系统的统计特性，编码论主要使用代数和几何等工具为各种应用环境设计有效的编码。

In this thesis, we propose a self-detecting algorithm for the nodes of a wireless sensor network to determine the event boundary in the presence of faulty nodes. The nodes exchange messages and execute the algorithm in parallel to determine whether they are located on the boundary of an event.

在这篇论文中，主要的目的是在一个无线感测网路环境下，如果当事件发生时，每一个感测节点如何透过单纯的资料交换和平行演算法来达到自我侦测并且判断出本身是否位於事件的边缘。

This "internalist" approach differs from the orthodox "externalist" approach of most adaptationists who see ubiquitous natural selection as the major shaping force.

而这样的一种"内在论"的研究通路，不同于那种为绝大多数环境适应论者所持有的、正统的"外在论"的研究通路，后者认为无处不在的选择才是在塑造有机体外形的主要力量。

Environmentalism is hot right now: it even featured on a recent cover of VanityFair, with Julia Roberts as a green fairy, George Clooney fetchingly attired in peasant gear and Al Gore brooding earthily.

当今环境保护论异常火热：甚至在最近一期VanityFair杂志封面上出现如下场景：朱丽亚罗伯茨是一位绿色环保仙女，乔治克鲁尼戈身着农民服饰，戈尔则席地而坐。

The immergence of the "Neo-imperialism" can be traced to several reasons, such as its comprehensive strength, its ideology and the international environment.

新帝国论的产生具有国力、思想意识、国际环境等方面的原因，但由于受限于国际因素与国内政治，又面临着重重困局。

Left-wing literati who dominated Hong Kong literary circle launched different animadverts including attacking Xu Zhong-nian\'s materialistic view of literature, Gu Yi-qiao\'s renaissance and Qian Zhong-shu\'s Fortress Besieged. The phrases and tactics they used settled the basic form of criticism in New China.The First Congress of Literary and Art Workers was convened in Beijing in July 1949. Its reconstruction of literatus under the delegation system, its dense political and martial atmosphere, and its rewriting of May Forth literature, all symbolized the establishment of new literary pattern and the commencement of "contemporary Chinese literature".

首先，考察战后香港文学环境的大体状貌及左翼文化活动的主要内容；然后，逐一梳理左翼主流派发动的各类批判，着重分析对徐仲年"唯生主义文艺观"、顾一樵"文艺复兴论"和钱钟书《围城》的批判；最后，概括左翼文艺批判的基本范式。1949年7月，第一次文代会在北京召开，其代表制对作家队伍的重构、政治领导文艺的氛围、对"五四"新文学的重新叙述，都表明新的文学格局已经形成，"当代文学"的进程已经开始。

At first, a graph about the environment can be built based on the sample data generated from a Markov decision process.

首先，基于马尔可夫决策过程抽样得到的样本数据建立环境的图论描述。

To solve this problem, based on the concept of graph theory we give a few models and arithmetic designs of virtual backbone in the environment of different application, and propose the corresponding routing mechanism with these virtual backbones. The major achievements are outlined as follows:The state of host's power or the time of host's online plays an important role in keeping stability of a virtual backbone. With a view to this feature, the paper introduces a simple and efficient heuristic algorithm for calculating the virtual backbone by seeking a minimum connected dominating set with maximal weight. The maximality of the weight-based choice of backbone nodes guarantees that the most suitable nodes have been chosen for the role of backbone nodes so that they can properly coordinate all the other nodes and keep stability of the virtual backbone in the network.

为了解决这个问题，本文利用网络图论中的一些理论，在不同的应用环境下给出几种虚拟骨干网的模型、构建及基于稳定性和节能的算法设计，并针对这些骨干网提出相应的分层路由机制，主要研究内容和贡献如下：考虑到主机的功率大小和在线时间长短对虚拟骨干中心的相对稳固性的影响，提出用基于极大权的最小连通支配集模拟虚拟骨干网；并给出其数学模型和相应的启发式算法，确保了性能强的主机担任骨干节点；通过优化规则确保骨干网的极小性，有效地减小了控制分组转发开销；最后进行了仿真验证。

国外学者已开启了这方面的探讨，但仍缺乏系统的比较研究，参见：约翰·麦克尼尔《论环境史中的自然与文化》，J。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
