中文摘要论文摘要论文名称：以讯息平台与行动通讯为基础之紧急医疗资讯系统台北医学大学医学资讯研究所研究生姓名：洪培修毕业时间：91 学年度第 2 学期指导教授：刘立台北医学大学医学资讯研究所副教授本研究目的是以讯息服务平台与行动通讯为基础，来提供各项即时的卫生医疗资讯服务，藉由所规划的架构蓝图及各种无线媒体传输的特性，将目前可供应用的资讯存取途径整合在一起，使卫生医疗资源资讯个人化、透明化并受到妥善的规划及运用。

It took me quite a long time to access several different files to find the correct information.

我花了好长时间存取了好多文件才找到所要的信息。

Route incoming calls to the correct application ( fax, answerphone, remote access ) depending on the criteria; Time, Day of week, Distinctive ring and caller number.

路线传入的呼叫到正确的应用（传真， answerphone ，远端存取），视乎有关标准；的时间，一周内每天的，独特的环和来电号码。

Topics include: mathematical definition and properties of information; source coding theorem, lossless compression of data, optimal lossless coding; noisy communication channels, channel coding theorem, the source-channel separation theorem, multiple access channels, broadcast channels, Gaussian noise, and time-varying channels.

课程主题包括：针对「资讯」的明确数学定义及性质描述；信源编码理论、无失真资料压缩技术、最佳化无错误编码；杂讯干扰的通讯频道解析、频道编码理论、资讯来源-通道编码分离理论、多重存取频道解析，广播型态频道解析、高斯杂讯及多变量时间频道解析。

Vopt is a disk defragmenter that includes batch and scheduled defragmentation options to keep your disk performance at an optimal level and can show information and statistics for file usage, fragmentation, and more all combined in a visually rich yet compact environment. It offers advanced features to override NTFS packing style, exclusion of large files and specific paths, as well as strategic placement of file to improve defragmentation speed.

硬 盘长时间安装软件或者删除文件变的凌乱，这样不仅硬盘存取资料速度变慢也会影响系统效率，虽可以利用Windown内附的磁盘整理程序来整理硬盘，但速度并不是很快，想找其它Windown用的磁盘整理程序取代，Vopt可将分裂在硬盘上不同扇区的文件快速和安全的重整，帮你节省更多时间。

But in DRAM, each memory element is a simple transistor using the internal capacitance between electrodes to store a small amount of charge as one bit of information, since this charge dissipates with time, it must be recharged or refreshed periodically to keep the information (usually 2 milliseconds).

但是在动态随机存取储存器中，每种记忆元素是一个使用在电极之间的内在容量储存如点点的数据很少的费用简单的电晶体，因为这一项费用以时间发泄，它一定定期地被再休整或生气蓬勃保存数据。

The controller uses the data write buffer to reduce the data access waiting time, and employs the two ways of duo channels instruction pre-fetch buffer to decrease the fetching instruction waiting time and increase the instruction pre-fetch buffer hit rate. Meanwhile, to reduce the waiting time aroused by page miss of SDRAM, a four ways of on chip stack memory is introduced. Compared with traditional controller through experiments the novel SDRAM controller gets a high reduction up to 63% in access waiting time and 64% in page miss.

该控制器采用数据写缓存方式降低了数据在存取内存时的等待时间；并引入了两组双通道预取指令缓冲器，每组双通道都用以减少取指令时的等待时间，采用两组的结构是为了增加指令预取的命中率；同时还使用了四路组关联的片上堆栈存储器来降低SDRAM的页失效频率，从而降低了因页失效而需要等待的时钟周期。

Different types of memory, including RAM, RAM cache, ROM, and CMOS, and the importance of memory access time are explored.

记忆的不同类型，包括随机存取储存器，随机存取储存器隐藏所、 ROM 和互补型金属氧化半导体，和记忆通路时间的重要性被探究。

Even though time needed for one memory access is quintupled, caching permits performance to remain reasonable.

尽管每次内存存取的时间是很大的，高速缓存使执行的时间还是可以接受的。

So in this paper we discuss the content of version management from data storage, and put forward two models of difference storage. Constructing storage threshold unites difference storage and full storage in order to balance space efficiency and time efficiency. It not only improves the answer time of version access but also reduces storage space.

因此本文从数据存储的角度讨论了版本管理的内容，提出两种差值存储模型，构造了版本存储阈值来将差值存储与完整存储相结合，从而有效地在空间效率和时间效率上进行平衡，不仅提高了版本存取的响应时间又减少存储空间。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
