First, the definition, significance, research emphases and status of NC machining verification technology are introduced in this paper. Then the platform—ACIS for the development of verification system, including its development interface, data structure, main functions, features and the application in the system is introduced. And, we indicate in brief the correlative knowledge of NC machining and then discuss the definition of the machining environment of NC machining verification system as well as the way that the module has been developed. Finally, we describe how to make Help Files and the structure of the Help Files in the system.

The fixed asf wmv wma files can skip the damaged data block, and continue to play.

固定ASF文件格式WMA文件可以跳过损坏的数据块，并继续发挥。

There is an introduction to Mars meteorites, and detailed descriptions of individual Mars meteorites. Each document about the individual meteorites contains all existing information such as petrography, whole rock and mineral chemistry, radiogenic, cosmogenic and stable isotope data and weathering.

该站点详细的介绍了火星陨石及其各自的具体特点，这些以PDF格式保存的档案文件包含了岩石记述学、岩石和矿物化学、射电数据、宇宙测年数据、稳定同位素数据等。

If want the data of built-in in HTML page of the static state trends, and these dynamic data are the word that will offer by the program such as ASP, PHP, so every time a person visits your website, the server is about to carry out and handle Tongji.asp document, from the data with draw-out and relevant database, reexport shows to the webpage, if tens of thousands of person is visited at the same time, be about to be carried out tens of thousands of times, consequence cans be imagined.

假如要在静态的HTML页面里嵌入动态的数据，而这些动态的数据是由ASP、PHP等程序来提供的话，这样每次有一个人访问你的网站，服务器就要执行并处理一次tongji.asp文件，从数据库抽取相应的数据，再输出给网页显示，假如有几万个人同时访问，就要执行几万次，后果就可想而知。

Because RIA transmit the data by file based XML standard. And GIS data is high secret sometimes. So in the representation tier components design, the data security must be considered.

由于RIA技术使用基于XML标准的文件传送数据，而GIS数据具有一定的敏感性，因此，设计表现层构件时需要考虑数据安全。

Undoing a block does not require an expensive sequential scan of a log file. It is simply a matter of locating the right version of the data block within the database.

还原数据块时无需执行代价高昂的日志文件顺序扫描操作，而只需在数据库内确定数据块的正确版本即可。

The metadata management server, which we call manager, is responsible for storing and maintaining system metadata(including file inodes and superblock), and it also records the data location in the clients' caches so as to preserve cooperative cache coherence.

元数据管理服务器除了存储及维护系统元数据（如文件索引节点和超级块）外，还记录了数据缓存位置，并维护合作式缓存的一致性。

The new control and data collecting system can run on WINDOWS system. The data of tapping toque can be input into EXCEL software system to deal with. This new system realize showing of the data on line so it is useful to monitor the condition of the tapping.

在对"一种振动攻丝在线故障诊断的方法及其装置"进行系统分析的基础上，提出了对其进行改进设计和再开发的工作思路，并优化设计了振动攻丝控制与数据采集系统的硬件电路板；把原有系统的操作平台提高到WINDOWS操作系统；攻丝扭矩数据可以存入文件或直接写EXCEL进行处理；实现了攻丝扭矩数据的在线采集和动态显示。

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

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。
