Compared with the testing set given by the specification, this instrument has the characters of automation, high accuracy, security, transplantability and extensibility.

该设备具有自动化程度和精度高、安全性强、可移植性和可扩展性强的特点。

Furthermore, to improve the expansibility and transplantability of the system, AIIDS is implemented as a JADE based multi-agent system and employs Java to develop.

同时，为了加强系统的可扩展性和可移植性，AIIDS利用多代理系统进行实现，采用Java作为开发工具，整个系统在JADE(Java Agent Development Environment)平台上进行开发。

The system is developed in the JAVA programming language. Based on themulti-tier model in the architecture of J2EE and the Struts framework in MVCmodel, it shows strong reliability, usability, maintainability, transplantability, andextensibility.

本系统的开发使用JAVA语言，基于J2EE架构中的多层模型，采用符合MVC模式的Struts框架，具有很好的可靠性、可用性、可维护性、可移植性和可扩展性。

The main features of this paper is: nothing to do with the platform, this system can be compatible with the majority of software and hardware used by the platform, as well as various database platform, shielding the differences of hardware and software platform such as network, operating systems, databases, application systems and so on, so that enterprises and institutions could achieve seamless, transparent data exchange through data exchange system; Java technology used to develop the system transplantability; using data exchange center to achieve centralized data processing, different data format conversion, increased system scalability; from data transmission, authentication, access control, encryption and more news content log-class areas enhanced data exchange system security; using DES and RSA algorithm , increased the confidentiality of data transmission; create WrapperTimer category achieved data transmission timing implementation and reduce the dependence on artificial.

设计的系统与平台无关，能兼容企业所用的大多数软硬件平台，以及各种数据库平台，屏蔽网络、操作系统、数据库、应用系统等软硬平台的差异，使企事业单位通过数据交换系统实现无缝的、透明的交换数据；采用数据交换中心来实现数据的集中处理、不同数据格式的转换，增加了系统的可扩展性；从数据传输、身份认证、权限控制、消息内容加密和多级日志等多方面增强数据交换系统的安全性；用DES和RSA算法对XML文件或XML文件中的元素进行加密，增加传输数据的保密性；创建WrapperTimer类实现了数据传输的定时执行，降低了对人工的依赖性。

This design has solved the problem which many wired networks are not easy to realize, For example: But the extension is bad, Transportability inferior question.

本设计解决了好多有线网络不容易实现的问题，如：可扩展性差，可移动性差等问题。

But most of these systems developed under Windows OS are stand-alone software using different database, therefore they have many shortcomings such as poor transportability, working inefficiency, bad scalability, bad maintainability, and etc.

但目前使用的科研管理系统大多是早期开发的Windows操作系统下的单机版软件，使用不同的后台数据库，普遍存在着可移植性差、工作效率低、可扩展性差、可维护性差以及部署麻烦等缺点。

It is studied the relation about the change and unchange of information system scheme,and put forward a new model of information syetem based on 3-Tier.

变革时期的企业信息化具有一些新的特点，本文对此问题进行了探讨，研究了信息系统结构中变与不变的问题，并在此基础之上提出了一种具有良好灵活性与扩展性的三层架构的信息系统模型。

It is discussed about some new characteristics of MIS of tobacco collectivize enterprise in reform times. It is studied the relation about the change and unchange of information system scheme, and put forward a new model of information syetem based on 3-Tier.

变革时期的企业信息化具有一些新的特点，本文对此问题进行了探讨，研究了信息系统结构中变与不变的问题，并在此基础之上提出了一种具有良好灵活性与扩展性的三层架构的信息系统模型。

There is unwounded coupling relationship for intercourse between the service provider and the service user in the system, and then there is preferable expansibility for this system.

因为服务提供者与服务使用者之间通过松散的耦合关系进行交互，系统的可扩展性很强。
