集聚

This thesis does a study of the following points: Firstly, the theories in theindustry cluster and the way to industry cluster were set forth, and then a study wasmade into the problems and countermeasures of improvement in the industry cluster.

本文的主要工作如下：首先，阐述产业集群理论和产业集聚的实现路径，并对推进产业集聚面临的问题与对策进行了探讨。

This article introduced the spinning principle of COM4,EliTe and Air-Com-Tex700 compact spinning set.

本文详细介绍了COM4、EliTe和Air-Com-Tex700集聚纺纱系统的纺纱原理，并对各种集聚纺纱系统存在的问题及不足进行了分析。

In another word, if we want to make an area have notable effect of agglomeration, the key does not lie in the size of advantage of agglomeration, but lie in the factors of elasticity of substitution of industry agglomeration.

或者说，要使一个地区有明显的集聚效果，关键不在于该地区集聚优势到底有多大，在于它替代其他地区的能力，进一步说，是在于集聚的替代弹性的影响因素。

From angle of external economy, knowledge spillover and social capital, the paper discusses the relation between corporation cluster, agglomeration economy, city location and development of urban services.

本文从外部经济、知识溢出和社会资本等角度分析了企业集聚、经济集聚状况、城市地理位置与城市服务业发展的关系，并利用分层线性模型检验了集聚效应对服务业差异的影响。

This article introduces the principle of compact spinning with mechanism of inspiratory trough-like roller compact spinning analysed.

介绍了集聚纺纱的原理，分析了气流槽聚型集聚纺纱的作用机理，并对集聚纺纱沟槽的尺寸进行了设计计算，分析了机构的力学性能。

Furthermore, it is researched into the intercorrelation mechanism of mutual affect between the three macro-factors and human capital evolution respectively.The effect and influence of factors on human capital was analyzed during the process of human capital flow between industries and regions by the core-periphery model of introducing human capital variable.

在探讨城市集聚背景下人力资本的历史演变的基础上，抽象出对人力资本演变具有关键作用的三个关联影响因素即产业集聚、知识集聚和制度因素，分别从这三个宏观因素出发剖析其与人力资本演变的相互影响及作用的关联机制。

At first, the article explores the factors causing the migration and conglomeration of population mobility and migration, by constructing the microeconomic model of population floating. Then, based on the analysis of the spatial distribution of population and industry, the article draws a conclusion that the population conglomeration of pro-developed region should adapt to the process of industry conglomeration, and the other developing region should adjust to the both the process of inverse flow of population refluence and the industry transformation.

通过构造人口流动迁移的微观经济模型，掌握人口流动、迁移和集聚的动因；通过人口与产业的空间布局分析，说明泛珠三角区域先发展地区的人口集聚与产业集聚过程应该相互适应，而后发展地区的人口"回流"与产业转移过程更应互为补充。

However, due to the substantially different allocation of resources in various geographic regions, along with their own characteristic formation, agglomerate economies show rather a strong tendency of unhomogeneity, which leads to the unhomogeneous characteristics of their advantages regarding FDI attraction. Therefore, this paper proposes there exists an interactive relationship between the primary advantage and the multi-level agglomerate advantages by dividing the latter one into original agglomerate advantage and late-developing agglomerate advantage.

本文认为虽然随着经济全球化和信息技术的进一步发展，基础性优势的重要性逐步下降，从一种显性优势转化为潜在优势，是东道国吸引FDI的一种比较优势，集聚性优势则起着越来越重要的作用，是东道国吸引FDI的一种竞争优势，两者之间存在着质的差别，但作为分别作用于国家和次国家两个不同层面上的优势，基础性优势和集聚性优势之间存在着互动互补关系，基础性优势是集聚性优势形成的前提，集聚性优势则是对基础性优势的提升，两者共同构成了东道国吸引FDI的二重优势，在东道国吸引FDI中缺一不可。

Influence of Additional Twist on Flax Cotton Blended Compact Yarn Property;2. By numerical integral of this model, the factors which affect the additional twist of yarn are analyzed, including the pressure in the profile tube and the coefficient of friction between the fiber band and lattice apron.

通过对集聚区内须条的集聚过程分析，建立须条变截面部分的力学模型，可以得出此部分须条是有附加捻度的，并且对影响这部分须条附加捻度的因素：须条与网格间的摩擦因数和负压的大小进行了分析，结果表明集聚区须条的附加捻度随着须条与网格间的摩擦因数和负压的增加而增加。

By numerical integral of this model, the factors which affect the additional twist of yarn are analyzed, including the pressure in the profile tube, the coefficient of friction between the fiber band and lattice apron, the length of the suction slot and the curvature radius of profile tube.

通过对集聚区内须条的集聚过程分析，建立须条的受力模型，发现须条在集聚过程中会产生附加捻度，并且对影响须条附加捻度的各种因素：异型管开槽长度、负压大小、须条和网格套圈间的摩擦因数以及异型管的曲率半径进行了分析。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
