Resource access and management is one of the most important key factors for grid computing. The agent union's social activity model is really suitable for resource management in computer system. This paper proposed a method for grid computing based on agent union. The method used agent union's society activities as foundation, realized resource control and management in grid computing with media service, policy management and dynamic negotiation in agent union.

本文在分布式基于主动对象的基础上给出了在一个World Wide Web上实现的全局工作流系统。文章首先根据Internet应用环境的特点与要求，对主动数据库中的ECA模型进行了时间和空间上的扩充，从而解决了主动对象在分布式环境下的时域和空域相关问题；其次，文章采用任务层次分解的方法建立起主动对象控制的工作流管理模型；最后，文章在相关模型和分布事件通信模式的基础之上，给出了World Wide Web之上的基于主动对象的全局工作流系统结构及其应用。

可视化软件开发平台所支持的数据模型和系统框架是决定可视化应用的使用范围与处理能力的两个重要特性。传统的可视化开发平台在多数据模型处理和与分离场景数据包容等方面还不能做到有效的协和与统一。本文采用扩充的软件体系结构的系统分析与设计方法，对大型可视化软件开发平台进行了基于软件体系结构的进化分析与设计，在较好的保持传统系统的原有特性的基础之上，有效的将一个只支持面模型处理应用开发的可视化软件设计开发支持平台进化扩充成为一个能够同时支持面模型和体模型应用开发的综合模型支持系统。

本文提出了一种采用Agent联邦技术来管理和控制的网络社区系统。基于Agent联邦的网络社区系统不仅在internet为核心的网络技术基础上突破了协同运作的时空局限性，而且还通过Agent联邦的控制方式解决了开放式网络环境下角色协作的自动化控制和智能化管理问题。

When we look back to the history of Internet, we can see that the need for human being to communicate with computers through Internet has made HTML the most popular tool for application of first generation World Wide Web on Internet. This fact gives us a sense that the need for more and more computers to communicate each other through Internet will make XML the mostly used technology for computers on Internet to exchange and store distribute data in near future. But even with the help of DTD and schema to today's XML documents & data sources, the programming works for programmers to integrate XML documents through Internet is still very hard and complex. One of the important reasons to this situation is that the programmers who want to integrate the XML documents have not only to analyze the document's original DTD, but also to write a new DTD for the new integrated XML data. Because DTD is really a specification for one XML document, it is only suitable for software & programs that have basic knowledge of DTD to analyze and create them. Based on the character of XML documents and their DTD specifications, this paper proposed a new system framework to use software agent to help the work for XML document & data integration. While software agents have DTD knowledge for them to automatically analyze and memorize the character of XML's DTD, they are absolutely effective in works of DTD analysis and XML creation. This character makes the system with the framework of this paper efficiently relieve the programmers' work by the automatic processing in XML document’s integration.
