数据共享

The research resloves the dual-port RAM's port competition problem and realizes the resource sharing between the master and the slave processor. Although in the higher sampling frequency, the acquired data can definitely be written into the flash in time.

解决了双口RAM的端口争用问题并讨论了极限采样频率，实现了主、从单片机数据共享，缓存采集信号，即使在较高采样频率下，仍能确保及时、可靠地存储实时信号。

The data sharing is based on an MMF.

数据共享是基于MMF的。

The dissertation also analyzes the design of the system from the view of availability, modifiability and performance. To improve those quality attributes, more detailed designs or modules have been added to the components and connectors.

本文还从质量属性的角度出发，分别在可用性、可维护性、性能三个方面对科学数据共享网系统的设计作了分析，为了提高这几方面的质量要求，更具体地补充设计了结构中的一些部件及它们之间的联系成分；而且对如何权衡质量属性之间相互作用的问题也做了分析和说明。

The management system of students realizes to make the college personnel management more scientific ,-informative and netty and data preservation more complete and standard . This system basically satisfies the personnel share for college management departments , and the network can complete the fundamental material s management of students and teachers which improves the col .

学生和教师管理系统实现了学院人事管理的科学化，信息化，网络化和资料保存的完整与规范，该系统基本满足了学院各管理部门针对人事方面的数据共享，通过网络完成学生和教师基本资料的管理，提高了学院管理效率；同时也可以满足包括教师绩效评估，学生综合测评，注册，学籍档案等人力资源的配套管理。

The method of reading the line, arc, spine, tolerances, surface roughness and full messages of the part from DXF file generated by AutoCAD is mainly introduced. Based on the study of DXF, a program interface is developed, by which the data can be shared among different CAD systems. According to the different Characters, the respective tool paths are designed. And by a machine configure file, the General postposition process is deal with. On the research of thegeneral simulation technology that is based on the NC codes. By analyzing the characteristics of the CNC system and the NC codes, a set of general simulation interface is developed.

本文主要介绍如何从AutoCAD生成的DXF文件中读取直线、圆弧、样条曲线、尺寸公差、表面粗糙度等信息及零件的全局信息，结合回转体零件的特点，通过对应用广泛的DXF的深入分析，建立了与不同CAD系统实现数据共享的编程接口；根据零件的不同加工特征提出了相应的走刀路线，并通过机床配置文件，初步实现了通用后置处理；研究了数控系统和NC代码的特点，建立了仿真通用接口，并提出代码翻译地基本思路。

In order to improve the efficiency of DBMS, Concurrent Control is the basic requirement on concurrent transactions execution. When transactions execute instantaneously, Lock Mechanism which could ensure transaction serializability is a good way. But the problem that LM produces should be faced.

并发控制是数据库管理系统提高运行效率的基本要求，事务并发执行时，采用锁机制是保证事务可串行化的一个方法，但因此而产生的死锁问题是一个必须面对的问题，其根本原因是由于数据共享的要求而造成的。

The amount of loss and sold-out of energy be calculated in the software.

软件中设计了电量统计和线损管理模块，实现了数据共享和Web查询，使用户可以通过网络查询自己的用电信息。

At the very beginning of C/S application, which was applied in only a single department , there was no necessary for Integration systems. But the need for Integrating systems into a more complex system is increasing, mainly because new and more useful solutions can be achieved, and enterprises need to consider the business process problems. If the single systems still run singly, they must be lack of the capacity of data-sharing and transaction-collaborating, and then become the infomation acnode in Internet. EAI could help enterprise solve these problems and improve the effectivity of whole system.The web is now evolving into a distributed device of computation from a collection of information resources.

在早期单一部门级小型C/S系统的应用阶段，企业和开发商并没有集成系统的需求与必要，随着企业实施的信息系统不断增多、范围逐渐扩大，企业也越来越多地将注意力集中在面向业务过程问题上，而这些各司其职的信息系统却缺乏互联互通数据共享事务协作的能力，形成了网络时代的信息孤岛，因此，企业应用集成便成了企业必须面对并需要解决的复杂问题，用来解决企业内部之间、企业与企业之间的集成，是多个系统能够相互协作，以提高效率。

According to the related new state regulations on explosive production, we have proposed a management-control integration mode based on the original automatically con- trolled emulsive explosive production line, that is, the combination of video control and on-site DCS automatic control.

根据国家关于炸药生产的新规定，在原来的乳化炸药自动控制生产线的基础上，提出了管控一体化的模式，即视频控制和现场DCS自动控制相结合，并与企业的管理网络互连，实现全厂级的数据共享和实时控制。

Presently, spatial data share has beenone of impendent unsolved problems in GIS.

空间数据共享已成为目前GIS领域迫待解决的问题。

This brought fixed cost, but it also is meant at the same time use a source to won't make you singlehanded assume a problem.

这带来了一定的成本，但它同时也意味着使用开源不会让你独力承担问题。
