Based on the rising suburbanization in China, this thesis focuses on the unique phenomena of large number of floating population flood into the suburb area. By using the integrated methods and views including sociology, demology, environmental science, the author studies on the causes of a series problems triggered by the huge increasing floating population and tries to use the new thought to resolve the problems.

本论文主要针对近年来在我国许多大城市进行工业郊区化的背景下，流动人口大量向城市郊区农村地区集中这一独特现象进行研究，综合运用社会学、人口学和环境科学的观点和方法，对这一过程中郊区农村因外来流动人口剧增而引发的一系列社会、环境问题的产生原因进行探讨，并寻找解决问题的思路。

According to the 1991 Northern Ireland census, there remained only 131,974 people, or about 8.8% of the population who could speak Gaelic, particularly on the southern and western regions of the country. The greatest urban concentration of Gaelic speakers, however, was in Belfast, where 27,430 were found. In second place with metropolitan Derry, with 9,731 people. In a few Local Government Districts, Gaelic speaks numbered 30% of the population, and even as high is more than 50%.

根据1991年的人口普查，目前北爱尔兰会说爱尔兰语的人数只有131，974，约8.8%，特别是在南区、以及西区，不过，人数最多的还是在贝尔法斯特，有27，430人，其次是在第二大都会区 Derry ，有9，731人；在一些「地方政府区域」，会讲爱尔兰语的人超过30%、甚至於一半以上。

Changes in the trends for a given phytoplankton population—such as its density, areal distribution, and rate of population growth or diminishment—will alert Earth scientists that environmental conditions are changing there.

地球科学家通过观察某一特定种群在密度、空间分布及种群数量增减方面等等的变化趋势，就能够判断当地的环境条件正在发生着改变。

CBFEC emphasizes direct correspondence of concepts in EC with its software architecture for ease of understanding and using; minimal coupling with specific problem structure for easy adaptation it to solve a large number of wholly different problems; interface-centered design for extendibility. To achieve those objects, the problem-solving method of EC is analyzed and the problem-solving procedure of EC is divided into three interactive aspects: population-based stochastic searching mechanism, problem specific information to implicitly guide the stochastic searching, and the observation and control of the computation procedure of EC. Then the key concepts of EC are identified in those three aspects; the normal implementations of those concepts are summarized; the interfaces represents those concepts in software are abstracted; the collaborations of components through those interfaces are designed. CBFEC is implemented on mainstream component software platform COM/DCOM (Component Object Model/Distributed COM from Microsoft), which includes interfaces definitions, commonly using EC components implemented those interfaces, such as Simply EA component, Steady State EA component, EA component, EA component, Population component, Tournament Selection component, Linear Ranking Selection component, Nonlinear Ranking Selection component, Random Number Generator component, etc, and the collaborations of those components through those interfaces.

具体的做法是把演化计算看作是基于组件的软件工程的一个应用领域：首先分析了演化计算求解问题的一般思路和方法，把演化计算问题求解过程分为："设计基于群体的随机搜索机制"、"研究问题的性质并以此隐含地定义算法的搜索方向"和"求解过程的观察与控制"三个部分；然后分别找出各个部分中的关键概念，总结这些概念现有的一般实现方法，抽取其本质，以此结合设计模式来定义组件软件的接口；通过分析演化计算各个概念之间的相互联系来设计组件软件间通过接口的进行交互的方式；最后还在目前一种主流组件软件开发平台COM／DCOM（微软提出的组件对象模型）的基础上实现了常用的演化计算组件，如简单演化算法组件、稳态演化算法组件、演化算法组件、演化算法组件、种群组件、锦标赛选择策略组件、线性排名选择策略组件、非线性排名选择策略组件、随机数发生器组件等等。

Trying to solve the problem of 'difficult to see a doctor and expensive to see a doctor' as a matter of fact is to treat means as the goal, which disproportionally uses tax payer's money to protect the interest of a smaller group of population, scarifying a larger group of population (relatively disease-free group).

解决群众反映较多的"看病难、看病贵"问题的做法实际上是把手段之一当成目的了。把手段之一当成目的的结果是不成比例地强调了一部分人的利益，侵害或牺牲了大部分人的利益。

Using circle distance method and GIS software, we obtain the detailed data on Shanghai's population distribution at street/town level, based on the 4th and 5th Population Census.

文章首先运用圈层距离法和GIS分析软件，在全国第四次和第五次人口普查数据中提取并获得上海市街道人口分布数据。

The results are as follows: 1 mean length and weight tend to increase while dominant length and weight groups are noted to be increasing from Oct. 2004 to Sep. 2007; 2 by using length-weight formula, calculated weight value at the same length is higher for track-data than that for background-data; 3 growth parameters of L∞, W∞ and K respectively increase from 140.5 mm, 36.5 g and 0.28 a-1 to 186.0 mm, 118.5 g and 0.36 a-1 after artificial reef deployment; 4 appreciable increases are noted in body length and weight growth rate after artificial reef deployment, and inflexion age of weight growth increases from 2.55 to 2.58 years after artificial reef deployment; 5 there is an increase in critical biomass age from 3.21 to 3.77 years after artificial reef deployment; 6 there is a decrease in total instantaneous population mortality from 1.065 to 0.75 per year after artificial reef deployment; and 7 the overall population biomass of small yellow croaker stands at 131.5 tons.

结果表明：投礁后小黄鱼的平均体长和体重均呈上升趋势，优势体长组和体重组均向高值移动；同等体长情况下由投礁后体长体重关系式估算的体重比用投礁前的体长体重关系式估算的值大；投礁后小黄鱼个体生长方程的参数 L∞、W∞、K 值分别从投礁前的140.5 mm、36.5 g和0.28 a-1增加到186.0 mm、118.5 g和0.36 a-1；投礁后体长与体重生长速度与投礁前相比有所增大，且体重生长的拐点年龄从投礁前2.55 a提高到2007年的2.58 a；小黄鱼种群生物量增长的临界年龄从投礁前的3.21 a提高到3.77 a；小黄鱼种群的总瞬时死亡率从投礁前的1.065 a-1减小到0.75 a-1；鱼礁区小黄鱼资源量约
