I introduction in this part , the research background and purpose gave been introduced firstly . then , the domestic and overseas research development of rural industrial structure have been summarized and appraised . lastly , the research ideas , methods of the paper have been explained 本文主要内容共分为五部分:首先阐述了研究的背景及意义,并对国内外研究的现状与动态做了综述,通过对不同国家的农村产业结构演进过程系统的分析总结,得到其演进的一般规律。
This real time data collection - management net system is integrated with existing systems , for instance desulfurize 、 extracting - vanadium process - computer system 、 steel - making ladle process - computer system and continuing caster process - computer system , and transmit producing sampling data to molds of computers which are in every producing process so as to develop the process of production 本文在介绍了该项目的基本条件、控制要求以及部分相关生产工艺过程管理系统基础上,根据实时准确、与现有的脱硫、提钒转炉过程系统、炼钢转炉过程系统和连铸过程系统、炼铁mis系统集成的原则设计了该数据采集系统。
My paper , firstly builds up a logic framework in the research , that is element mechanism , concept foundation ( avs ) and theory foundation . on elements mechanism layer , the paper not only extracts three key elements , that is host , information and environment , combined with other elements , but also builds up a model of element agreement and constructs appraisal process systematical structure as well as control flow chart . on concept foundation layers , the paper 按照这一逻辑层次,本文在要素机理层面,提取评估主体、信息、环境三大关键要素,结合其他要素构筑要素耦合图,并依此构造资产评估的过程系统结构图与控制流程图;在概念层面,确立资产评估价值标准( avs )这一核心概念的内涵( fmv ) ;在理论基础层面,首先澄清了资产评估的会计理论基础,然后依次(第三章与第四章)介绍了基于新古典经济学与博弈论的资产评估机理的特点。
The thesis describes the opc data access rules , interfaces and methods based on com technology , brings out a method of applying opc rules to implement a universal , open and standard method , presents an implementing scheme of opc client and gives out a industry process control system frame based on opc at last 针对传统工业过程系统中存在的不足,提出了运用opc技术,实现一种通用的、开放的、标准的数据采集方法。给出了opc客户端的具体实现,并提出了一个基于opc技术的工业过程控制系统应用框架。
