It is pointed out that the strategic emphasis is to build the industrialization central city of china s ev, according to the location strategic theory . the system characteristic and function of the industrialization central city are presented . the strategy implementation of the central city is proposed 根据产业区位战略理论,提出了我国应执行电动汽车产业化中心城市的区位战略;还描述了电动汽车产业化中心城市的体系特征与功能,并提出中心城市的战略实施要点。
This text starts with the theory of the analytical system and application while studying in coordinated development, defines comprehensive transportation compound systematic concept, analyses systematic structure and interaction mechanism at first, points out its systematic characteristics and coordinates the mechanism; from learn angle set out, define comprehensive transportation compound systematic concept of coordinated development in coordination, probes into its hierarchical structure and system characteristic, the system has developed the conceptual model in harmony after establishing comprehensive transportation and compound, and coordinates evolution and goal and carries on in-depth analysis to this system 本文从分析系统理论及其在协调发展研究中的应用入手,首先定义综合运输复合系统的概念,并分析其系统结构及相互作用机理,指出其系统特征与协调机制;从协同学角度出发,定义了综合运输复合系统协调发展的概念,探讨其层次结构与系统特征,建立了综合运输复合系统协调发展概念模型,并对此系统协调发展过程及目标进行深入分析。
Beginning with a series of modern enterprise theories, such as the origin of enterprise, characteristic, the foundation of property rights, rights distribution, agent theories and so on, this paper analyzes the foundational concept of state-owned enterprises, and studies the internal logic, system characteristic, object characteristic of existence and proves that the essence of all the problems that exist in state-owned enterprises, for example, lower efficiency and competitive power, insider control . . . is the system limitation of state-owned enterprises, that is to say, the internal contradiction between public-owned property rights and market mechanism 本文从企业起源、性质、产权制度基础、权利安排、委托代理理论等现代企业理论来分析认定国有企业的基本概念,研究其存在的内在逻辑、制度特性、目标特性,分析证明国有企业存在的诸如效率流失、内部人控制、竞争力低下等一系列问题的背后本质是国有企业的制度缺陷??公有产权制度与市场机制的内在矛盾,剖析由此带来的产权缺位与行为扭曲。
Building a framework of function-driven product configuration management system based on customization of web and making a detailed analysis and research on the system characteristics and functions based on the academic background on web-based customization and product configuration management . 2 . having a study on product configuration management idea in the system and bringing forward a function-driven product configuration management thought based on the analysis of functions in product and building the system model 本文主要进行了以下方面的研究:1、介绍和分析了基于web的个性化产品定制及产品配置管理的理论背景,在此基础上提出了一种基于个性化web定制的功能驱动产品配置管理系统的体系框架结构,该结构具有分布性、集成性和可扩展性等特点;2、探讨了产品配置管理理念,在产品的功能分析的基础上提出了功能驱动的产品配置管理思想并建立了系统模型;3、对配置管理系统中的产品配置过程进行了数学描述,对定制产品相似实例的提取算法进行了研究;4、以温州东华服装设备有限公司的干洗机系列产品为应用对象,设计和开发了原型系统。
After analyzing the advantage and disadvantage of some models ( such as cgi server apk plug-i activex java applet ) in constructing webgis, the paper analyzes the system characteristics and some application branches of a perfect net language-java, so all of this give prominence to the advantage of applying java in constructing webgis . then in view of software engineering the paper analyzes the superiority of developing component-based webgis by javabeans and practices the yunnan resort navigation system using maplnfo " s mapxtreme for java 3.1 beans . the system can provide some basal functions such as zoom in, zoom out, pan, adding theme, measuring and so on 接着论文分析了构造webgis的几种模式??cgi模式、服务器应用程序接口方法、plug-in模式、activex模式以及javaapplet模式的优缺点,进而阐述了网络语言java的系统特性及其各种应用分支,突出了采用java开发webgis的优势,然后从软件工程的角度分析了采用javabeans进行webgis组件式开发的优势,并具体试验了基于mapinfo公司mapxtremeforjava系列beans进行云南省旅游景点导航系统的构造,开发出的系统实现了地图显示、放大、缩小、漫游、添加专题等常规的gis功能。
