数字数据

For practicality, this paper designs a new digital access system, which uses the Atmel Corporation's AT89S51 and AT24C02 as the chief chip and data cell store, combined with the function of keyboard input, digital display, intelligent alarm, recording the information of alarm, Video interphone and intelligence alarm.

本文从经济实用的角度出发，采用Atmel公司的AT89S51单片机与AT24C02作为主控芯片和数据存储器单元，结合外围电路设计了一款密码开锁、数字显示、密码储存、报警信息记录、可视对讲和智能报警的数字门禁系统。

The primary technical issues with streaming were:· having enough CPU power and bus bandwidth to support the required data rates · creating low-latency interrupt paths in the OS to prevent buffer underrun However, computer networks were still limited, and media was usually delivered over non-streaming channels, such as download of a digital file from a remote web server that was then saved to a local drive on the end users computer or as a digital file stored and played back from CD-ROMs.

与流主要的技术问题是：·有足够的 CPU 电源及巴士的带宽来支持创建低滞后时间的所需的数据率·中断 OS 为防止缓冲区不足中的路径但，计算机网络仍然有限，和媒体通常送非流信道，该等作为数字从远程 Web 服务器的最终用户计算机上的本地驱动器，然后保存文件的下载或作为一种数字文件存储和播放从 CD-ROM 回来。

Digital carbonless is optimized for monochrome or color digital printing and positioned for applications that require offset preprinting with secondary variable-data printing.

数字无碳复写纸适合单色或彩色数字印刷和定位的应用，需要抵消预中学可变数据印刷。

It adopt technique by preventing from coping screen in postil 、 siginate and seal. It can siginate for manuscript and stamper basing on PKI by 1024 RSA arithmetic,assure distinguishing and preventing disavow.It can find nonlicet sophisticate of attacker by data fingerprint,protect data facticity and integrity.

其中手写批注、签名和电子签章采取了防截屏拷贝处理技术，基于国际公认的公钥基础设施体系，通过采用RSA算法（1024位）对手写笔记和印章进行数字签名，能保证手写笔记和电子印章的可鉴别性，防止对操作的否认与抵赖，同时利用数字指纹技术能精确的发现攻击者对文档的非法篡改，以保护数据信息的真实性和完整性。

Government figures record that more than 300 children died in Puno in May 2009 from the cold; NGOs say that the figure was probably much higher.

政府的统计数字显示，2009年5月，普诺地区有300多名儿童死于严寒；而非政府组织则认为实际数字有可能要远远高于这一数据。

By using integration classification systems, subject thesauri and semantic metadata, we can realize the knowledge organization of digital library.

利用集成分类法、主题词表和语义元数据构造数字图书馆知识组织系统的方法，可以实现数字图书馆的知识组织。

According to Newell and Simon, a physical symbol system is a machine, like a digital computer,that is capable of manipulating symbolic data-adding numbers, rearranging lists of symbols (such as alphabetizing a list of names), replacing some symbols by others, and so on.

按纽厄尔和西蒙的想法，物理符号系统是这样一种机器，就象数字计算机，它能处理符号数据，累加数字，重排符号表（如按字母顺序排列一个名称表），用一些符号替换另一些符号等等。

The huge challenge in digital image and video sequence is the great amount of data, which should be compressed and decompressed in practical work.

数字图像视频的突出问题在于庞大的数据量给存储和传输带来困难，因此数字图像视频的处理离不开压缩和解压缩技术。

In this paper, the characteristics and the principals of the digitalizing Erhai lake geo-spatial analysis are outlines firstly.

本文首先分析了数字湖泊地理空间分析的特性和基本方法，研究了紧耦合和松耦合两种建模方式；然后对湖泊区域数字地形的多尺度表达问题进行了研究，最后提出了湖泊区域不同尺度空间数据的组织方式和数据库建立的方法与技术路线。
