In general , there are a lot of equipments in embedded application system . the distributed processors are connected by the communication link . so it is important to implement the real - time and reliable data communication among these processors 在嵌入式应用系统中，通常包含很多功能不同的设备，分布的处理机之间用通信链路连接起来，因此如何实现各处理机间实时的、可靠的数据通信，即解决嵌入式分布系统中的进程间可靠、高效通信的问题，就成为一个关键。
There exist various services in guizhou power data network . the professional service systems have various functions and are independent each other . these professional service systems are separated logically in the network , and the access between them should be controllable and manageable in function designing 贵州电力数据网络系统存在多种业务,各专业系统功能不同、业务上独立,应在网络上逻辑分开,相互之间的访问也要在可控制、可管理的方式下进行。
The most applied geography information system are arc / info and pc arc / info and arc view made in esri company and maplnfo made in maplnfo company in usa and mapgis and geostar made in china , they differ from characteristic and function and using method and used range 目前应用最多的工具型地理信息系统是美国esri公司的arc info 、 pcarc info 、 arcview和mapinfo公司的mapinfo 、我国中地公司的mapgls和吉奥公司的geostar等，它们各有特点、功能不同、使用方法及范围不一。
According to the function organization system can be divided into bearing management function , bearing service function , having supervise function and the support organization ; the equipment system is constructed in two fields of the welfare hard equipment and the form of welfare service ; and norm system is divided into unrecorded informal system and recorded formal system . furthermore it particularly points out the importance to establish flexible management systems and operation mechanisms 对组织系统根据各组织承担的功能不同划分为承担管理职能的组织、承担福利服务职能的组织、承担监督职能的组织和承担支援职能的组织四种类型；从福利的硬件设施和福利服务形式两个方面对设备系统进行建构；而把规范系统分为不成文的非正式的规范系统和成文的正式的规范系统两部分进行了分析。
Based on the investigations of domestic and overseas road traffic safety researching , this paper studies the whole scheme of vehicle operation parameters monitoring system aimed at improving road traffic safety , selects the monitoring parameters which are classified by functions and their sensors , designs the sensor signal processing circuits , the software and hardware of ecu , the display and alarm circuits as well as anti - jamming circuits , realizes the functions of displaying , alarming and " black - box " , and forms a suit of practicality methods of designing vehicle running parameters monitoring system , provides references for research and development of other on - board intelligent devices 本文在分析了国内外有关汽车行驶安全研究成果和发展趋势的基础上，以汽车运行安全为目标，确定了汽车运行安全参数监控系统总体方案，选择了运行安全监控参数，并按功能不同进行了分类，选择了传感器并设计了相应的信号处理电路。完成了电子监控单元软、硬件的设计以及显示、报警电路和抗干扰设计，实现了汽车运行过程中安全参数的显示、报警和“黑匣子”功能，形成了一套汽车运行安全参数电子监控系统设计的实用方法，为其它车载智能化仪器仪表及相关仪器的研究开发提供了借鉴。
Flashget arranges download jobs in top - to - bottom order ; higher positioned jobs get downloaded before lower positioned jobs . we think this is much more intuitive . you can rearrange the order by selecting jobs and pressing the up or down arrow on the toolbar . tip : hold down the ctrl key when clicking up or down and you can move jobs directly to the top or the bottom in a convenient single step A .快车的下载优先级功能不同一般的下载软件，它是按照显示的顺序依次下载的，这样非常清楚，可以通过工具条的上下箭头来更改下载的顺序，按住“ ctrl ”键可以一次移动任务到列表的顶部或者底部。
