The traditional client / server structure ca n ' t adapt to the internet , a complicated distributed isomerous environment any longer . and the distributed module model , developing from the blend of object - oriented technology and distributed computing technology , is gradually becoming the standard technology of application of web database for its advanced function , transflat , portability and flexibility 传统的客户/服务器结构已经不能适应internet这样一个复杂的分布式异构环境，而由面向对象技术和分布式计算技术相互融合发展起来的分布式组件模型以其高性能、跨平台、可移植、可伸缩等特性逐渐成为web数据库应用开发的标准技术。
Mobile agent is the intelligent agent having characteristic of mobility , which can migrate from one computer to another in an isomerous network and complete appointed task of users such as computing , searching , filtrating and gathering information , so much as commercial activity . mobile agent has the characteristic of migration in addition to response , autonomy and intelligence 移动agent是具有移动特性( mobility )的智能agent ，它能在异构网络中自主地从一台主机迁移到另一台主机，代表用户完成指定的工作，如计算，检索、过滤和收集信息，甚至可以代表用户进行商业活动；移动agent除了具有智能agent的最基本特性：反应性、自治性、智能性外，主要的是它还具有移动性。
In the next place of the paper , the current situation of software in the electric power industry is analyzed . in order to integrate the datum of all isomerous systems , simple web services architecture is adopted to eai . a j2ee application invoking a web service provided by delphi is demonstrated here 文章接着分析了当前电力行业软件系统的应用现状，为了实现异构系统数据的整合，将简单web服务架构应用于企业集成，并给出一个j2ee应用程序调用delphi编写的web服务实例。
The paper raises a scheme to realize the peer - to - peer model using mobile agent , with the travel design patterns , the agents can move to a terminal , at where has the resources they may need , to execute task . a distributed isomerous database system is developed to test the above model , whose results are wonderful 本文进一步给出了利用移动agent技术实现对等模型的一种思路和方案，再利用移动agent的设计模式，设计一套用于cscw的对等模型，利用移动agent携带任务到拥有它所需要的资源的远程对等节点上执行任务。
Resources in grid environment distribute widely , change dynamically , and work on isomerous platform under control of different management policy , which presents uncommon demands to the information service , and makes the research on grid information service a significative and challenging task . this dissertation primarily researches into grid information service 网格环境下的资源地理分布极广,类型和数量巨大,动态变化,且工作在异构平台上由不同的管理策略控制,其复杂性对信息服务提出了不一般的要求,也使得对于网格信息服务的研究成为一项比较有意义且具有挑战性的工作。
Based on the next generation internet core protocol of web services and its relevant technologies such as xml , soap , wsdl and uddi , a novel solution of global - oriented distributed computing for networked manufacturing is put forward . the solution , which featured with distributed , isomerous , weak coupling and soft framework , enables enterprises and their partners to cooperate remotely more conveniently under the mode of multi - platform or / and multi - language , hence a genuine global - oriented networked manufacturing 论文运用最新的网络技术与规范webservices等，提出了一种面向全球的网络化制造分布式计算全新解决方案godc ，该方案具有分布、异构、松耦合、软架构的特性，使企业及其合作伙伴能够平滑的进行跨平台、跨语言的远程协作，从而实现真正意义上的全球化网络制造( global - orientednetworkedmanufacturing ， gonm ) 。
The structured design of profibus system indicated bus access protocol ' s advantages . then , to integrate all sub - system or devices into the synthetic system , it was put forward to lead the ethernet technique into the control network . to solve ethernet " real - time , full - duplex switching was adopted and the system " structure was optimized to solve ethernet " reliability , redundancy technique was adopted and isomerous databases between control network be adopted 对于配置灵活的优势，则列举了profibus - dp网络体系的构建过程及其通信软件设计的方便性，进行例证；对于总线存取协议，则将其支持多主-从结构的特点，与软件设计中的结构化设计概念联系在一起，提出profibus系统结构化设计的概念，并用实例验证了这个概念，以此证实profibus总线存取协议的优异。
