The methods of forecast the public transportation strategy : " maercofu " and it ' s deformation are put forward on the basis of analyzing the history public transportation data . the methods of forecast the public transportation o - d is make out : it is on the basis of the figure of the transit passengers get on and get off the bus on the spots 首先提出了马尔可夫链法及其改善方法,这一方法是根据历史调查数据结合定性分析,建立各交通方式之间的转移概率矩阵,预测现行的客运交通发展战略所产生的未来的客运交通方式结构,以分析公交发展策略的改善方向。
How to maintain a good relation with professional channels ? the thesis discusses above issue from several aspects . firstly , the definition and character of mass - decentr alized communication and the reflection of composite channels " development by charts and figures ; secondly , the reasons why composite channels are still a main part of media market , outlining the causes from three hands : the character of chinese audience , the present situation of chinese channels , mainly in the ability of producing programs and the models of some foreign channels excelling in producing marketing and so on ; thirdly , the strategy of composite channels " development , including the choice of programs , the arrangement of channel structure and the marketing strategy of famous - brand in the composite channels 全文主要从三个角度对综合频道的发展进行阐述:第一部分,概括了分众化传播时代的特点和实质以及用图表、相关数据结合理论分析近年来1 ,国频道发展过程中出现的一系列的问题:即电视剧仍是各频道播出节目的主体、一}了日1司质化倾向严重、频道资源的优化组合问题哑待解决以及频道划分不够科学和合理,频道定位不明确;第二部分,从中国电视受众的实际情况(包括受众的年龄、性别、教育程度、家庭收入、观众的收视行为、文化产品的消费习惯、思维习惯和收视心理) 、中国的媒介大环境(主要是节目制作能力) 、国外的传媒环境(侧重于abc7频道和法国电视二台的经验分析)三个方一面阐释综合频道仍能继续发展、大有作为的原因;第三部分,也是全文最重要的部分?中国综合频道的发展,钱略。
To solve these problems , it is put forward that components technology and using the essential idea of geography information system ( gis ) : combing the spatial geography graphic data with their property data are used in the development of generic cabling management system ( gcs ) software , to develop one small scale applied gis 针对这些问题进行了研究,提出了将组件技术应用于综合布线管理系统的软件开发,并将地理信息系统( gis )的空间数据和属性数据结合的基本思想应用于综合布线管理系统中来,开发这样一个小规模的应用型gis系统。
In this paper , the ecology environmental information system based on gis , gave up the traditional method and stepped out a new pace in translating from the traditional management of statistic data to the management of spatial data in this way , the system can construct the ecology environment management and decision making on the base of the joint of spatial data and attribute data 使生态环境管理与决策建立在空间数据与属性数据结合的基础上,通过空间数据与属性数据的结合,进一步进行空间分析,挖掘隐藏在数据背后的信息,通过gis可视化的功能使信息及空间分析的结果以各种直观图形、图表、多媒体的方面显示出来,并可以进一步通过网络进行生态环境信息共享。
In the following chapters , the interoperable model of webgis , multi - level b / s architecture , multi - thread for network computing and concurrent access , dcom , intelligent agent , intelligent spatial search engine , information security are discussed in detail . with these key technologies , the system of publishment and analysis of city air quality based on webgis is designed and implemented 借鉴这些关键技术,在arcims的基础上,设计并实现了基于webgis的全国重点城市空气质量发布系统,将空气质量状况与空间数据结合起来,生动直观的反映了各主要城市的空气质量状况,方便了用户的查询,为环保事业作出应有的贡献。
