Application software is designed and developed by b / s model , adopted general data access or general xml data documents to realize data exchanging ; the application software system consists of three main sections : integrated oa , kinds of professional management systems ( such as client service system , billing system ) , knowledge management and determination support system 应用软件以b s模式设计开发,采用通用的数据接口或通用的xml数据文档,实现数据交换,应用软件系统包括了综合办公信息系统、各类专业管理系统(如客户服务系统、营业系统、计费帐务系统等) 、知识管理和决策支持系统三大部分。
Non - point source pollution metadata of the three - gorge reservoir area in chongqing not can only help manage and maintain huge data , set up data document , know about data items of the non - point source pollution study in three - gorge reservoir . provide data format , projection , scale , etc . , but also can provide effective way and technicle means for spare data and comm 从评价结果中可以得出重庆市三峡库区面源污染危险性高和较高的区域占全库区面积的3 . 71 % ,危险性中等的地区占整个流域面积的6 . 76 % 。
Given that the drawing of plane arrangement maps of electrified railway contact net is one of the important junctures of the whole contact net design , starting from the perspective of system , the paper firstly analyzes the drawing task of the plane arrangement maps of railway contact net in details and presents the structure and function of the system , secondly discusses the formulation of consumer menu and dialogue frame and lists the main controlling program of dialogue frame , then by analyzing the involved data of originally drawing course gives and realizes the management of the original drawing data , which achieves the drawing of choosing inter - station and station , the establishment of drawing papers and drawing form , the setting - up of character height and the drawing form coordinate points and drawing starting points and the preserving routes of data documents of drawing form and the note - marking column and the size of subsidiary table 系统是基于autocad2002平台,在visuallisp环境下,采用面向对象的编程方法,运用参数化设计的原理,设计开发了运行于windows9x ~ xp上的电气化铁路接触网平面布置图参数化绘图系统。电气化铁路接触网平面布置图的绘制是接触网整体设计中极其重要的一环,本文从系统的观点出发,首先对铁路接触网平面布置图的绘制工作做了详细分析,提出了系统的结构和功能;然后详细讨论用户菜单及对话框的定制,并列出主要的对话框控制程序;接着通过对初始化绘制图形过程中所涉及的数据的分析,提出并实现对初始化绘图数据的管理。
