索引文件

Eugene Garfield published a paper in science entitled "citation indexes for science: a new dimension in documentation through association of ideas".

Eugene Garfield发表过一篇科学论文，名为"科学引证索引：一个通观关联信息编制文件的新时代"。

The number of bits per pixel allocated for storing indexed color information in a graphics file.

位深度 图形文件中为存储可索引的颜色信息而给每个象素分配的位数。

Set up the essential tools of catalog, card and index, and the files marshal as well.

根据工作需要，编制必要的目录、卡片、索引等检索工具，编辑档案文件汇集等参考材料。

Projects can also pre-define a set of index card templates corresponding to different categories of documents.

计划也能预先定义对文件的不同种类符合的一组索引卡片型板。

With Max Data Recovery, you can quickly recover and rescue corrupted, unopenable, or unreadablefiles.

该软件支持恢复类似于文档、应用软件、音乐文件和图像这样的索引类型的文件。

If there is enough interest, I may extend the project to use the document filters from the Nutch web crawler to index PDF and Microsoft Office type files.

如果有足够的兴趣，我可以将项目使用从Nutch是网络抓取的文件过滤器，索引PDF和微软Office类型的文件。

Traditionally, full-text searching systems were usually based on inverted-index, which is usually huge in volume and unsorted. That makes users suffer from easily determining the information embedded in the collection.

传统上仰赖反转索引档为基础的全文检索技术，往往搜寻出相当庞大且杂乱的文件资料，所以还需经过进一步的筛选，才能找到真正有用的文件。

From ORACLE system structure, the paper organizes and allocates memory with SGA and PGA. The key of performance tuning is to confirm the hit ratio of system. The ORACLE system's store structure includes physicial structure and logical structure. So , it is the basis to decide the size of tablespace, data file and control file. The database object includes index, cluster, views and store procedure etc., the object have important effect on database. Lastly, it contrasts the ways of Based on Cost and Based on Rule and organizes the SQL under SQL/PLUS system environment.

本文从目前的医院信息系统现状分析，提出系统性能评价指标，并从ORACLE体系结构出发，对内存区中的系统全局区及程序全局区进行合理的组织与分配，确定合理的命中率，这是性能优化的关键；ORACLE存储结构采用的互为关系的逻辑存储结构与物理存储结构，故确定其中的表空间、数据文件、控制文件的大小是性能优化的基础；数据库对象结构中的索引、簇、视图、存储过程等对其进行合理的设计，对大型数据库的性能有着重要的影响；最后便是在SQL／PLUS境下，通过与基于代价与基于规则的方法进行比较，对合理高效的SQL语句进行组织，并列出优化后系统性能的情况。

To prevent against this without creating lots of new 'index' files, you can enter a command into your .htaccess file to stop the directory list from being shown

为了避免这种情况（而不必创建一堆的新index文件），你能在你的。htaccess文件中键入以下命令，用以阻止目录索引的显示

In the United States, chronic alcoholism and hepatitis C are the most common ones.
