Laboratory equipment managements system is a typical management information system, the system is a software system that adapts to the urgent need of management of laboratory equipments to school, the development including two aspects, one is the establishment and maintenance of the background database , the other is the development of fore-end application. After analysis and comparison, we decide to use ASP and SQL as the development tools, use various object-oriented development tools. Especially the data window , an intelligent database objects which can control the database conveniently and simple. First establishes application system prototype in a short period of time, and then, carries out the need iteration on the initial prototype system, constantly revised and improved, till to the viable system that the users satisfy

摘要实验室设备管理系统是一个典型的信息管理系统，本系统是一个为适应对学校实验室设备管理的迫切需求而设计开发的软件系统，其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面，经过分析和比较，我们决定使用ASP和SQL作为开发工具，利用其提供的各种面向对象的开发手段，尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象，首先在短时间内建立系统应用原型，然后，对初始原型系统进行需求迭代，不断修正和改进，真到形成用户满意的可行系统。

Database, GIS and. Then, the design of the survey database in detail: Requirementanalysis, and function design. Then the impletion of the surveying spatial database inclass view.

The system can receive data from the STEP-NC interpreter by using the resource model of the function block type database, then translate the receiving data into the data of function block format; the tool path generator can dynamically transfer the function block in the function block type database; it can also use the data of function block management resource to export DSP order; depending on VC to edit function database and Dynamic Linkable Library, we can connect the tool path generator with research platform, use the tool path generated from the tool path generator to drive the tool move.

结果 通过功能块类型库中的资源模型接收STEP-NC解释器解释的数据，并将接收的数据转化成功能块格式的数据；依据工艺规划好的加工工序，刀具路径生成器动态调用功能块类型库中的功能块；利用功能块处理资源提供的数据，输出DSP指令；依靠VC语言编辑函数库和动态链接库，将刀具路径生成器与实验平台建立关联，基于刀具路径生成器生成的刀具轨迹驱动机床刀具运动。

The multiple-database model can be used to work around the conflict situations inherent in long lunation database sessions.Since each user from the shared database and work against.

多个数据库模式可用来围绕长期数据库对话所固有的矛盾形势而工作，因为每一个用户可从共用数据库拷贝数据这不同于他／她的专用数据库，该数据库与共用数据库至少在表面上分开，这样用户就能避免矛盾形势。

This Memory Resident Database Supply these features: Definition of data(table、index、queue et), operation of data; synchronization of data: Data synchronous abilty is pivotal function to distributed DBMS(synchronization of static data, dynamic synchronization between master processor and slave processor); database power-on; Saving and Loading of database etc.

根据系统设计的要求该内存数据库提供以下功能：数据定义，数据操作（数据的插入、删除、修改、查询）；数据的同步机制：数据的同步功能是数据库系统保证分布、备份数据系统一致性的关键(各模块之间的静态数据同步、主备MP大量数据的动态数据同步、MP间动态数据同步)，其中本文主要介绍了主备MP的动态数据同步；数据库系统并发性控制。

Based on the Fact Sheet: Journal Selection for Index Medicus/MEDLINE and the Fact Sheet: Response to Inquiries about Journal Selection for Indexing at NLM, this article was to introduce the MEDLINE database, the process of applying a journal to be indexed in the MEDLINE database and review process. Meanwhile, this paper was to share Tzu Chi Nursing journal Editor's experiences in applying the Tzu Chi Nursing Journal to be indexed in the MEDLINE database, and hopefully these experiences can provide other nursing publishers with a reference.

本文参考「MEDLINE期刊筛选条件之说明」与「申请加入国家医学图书馆资料库之说明」此两份文件，兹对MEDLINE资料库、申请加入MEDLINE资料库之过程以及审查过程做一简明介绍，同时也分享慈济护理杂志总编辑向「美国国家医学图书馆」提出申请「慈济护理杂志」加入MEDLINE资料库之经验谈，期望此经验可做为其它护理杂志社的参考。

In the design and implementation of the database applications part,this paper introduces a method of progressive expansion to design concept structure of the database, and put forward the "pseudo-code" to solve the existing problem in modification complexity and large data redundancy after using the traditional method of normalization theorem to process the database.

在该系统数据库设计与实现部分，本文介绍了运用逐步扩张的方法设计本数据库概念结构过程，并提出了"伪码"的概念以解决利用传统规范化理论处理后数据库存在的修改复杂、数据冗余度大的问题。

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

关系数据库上的关键词检索已成为数据库和信息检索领域的研究热点之一现有数据库关键词检索系统可分为在线和离线两大类，它们都难以兼顾查询效率和效果：在线系统能够获得数据库最新结果，但速度较慢；离线系统使用预处理提高查询速度，但若数据库更新就要重新执行预处理。
