Based on the "Structural Holes" theory and the concept of "Bridge",combined with the characteristics of the sharing, divide the "Bridge" into five types. Discuss the role of the five types in sharing; Based on the results of the UCINET analysis, express the coordination role of coordinator, and give a optimization way of the inside network; Divide the broker into two types, and make a description of the two types' function in details; Integrate the discussion of gate keeper and representative, and descript the different function of them on the same system; Descript the function of the Simmel model,and illustrate the bad effect of the model and give measures to avoid that.

在简述"结构洞"理论和"桥"的概念的基础上，结合科技资源共享的特点，把"桥"划分为5种类型；对不同类型"桥"在共享中的作用进行论述；基于UCINET分析结果说明协调者的协调作用，并提出内部人际网络优化方法；对中介者进行再次分类，并详述两种模式在科技资源共享中的功能实现；将守门人与发言人综合论述，描述在同一个体系下实现两者不同作用；对齐美尔连带的作用进行论述，对其可能产生的负面影响进行说明并给出相应的避免措施。

While library resource sharing is shifting to the new networking environment era, it is also in face of a lot of new challenges and"Access versus Assets"is becoming the new theme of the resource sharing in this new networking era, based on this point this thesis studies the development and the transformation of the resource sharing both in practice and in theory in the networking environment, particularly focus on a serial of issues, including the construction of resource sharing system, digital information resource, digital library, interlibrary loan, document delivery service and collection development etc. The writer also analyzes the coexsitence of the traditional resource sharing and modernizational resource sharing and the relationship between them in 21st, explores the revolutionary changes of resource sharing as the"Assets"model is driving to the"Access"model, discusses the development of specific collection for a single library and how to construct a seamless integrated information resource system in the networking environment, systematically studies and introduces the new organization model of resource sharing, especially emphases that document delivery is the key of the success in resource sharing, and finally tries to outline the main trends which will influence resource sharing.

本文立足于网络环境下资源共享的新主题：存取与拥有，研究和分析了网络环境下资源共享及其体系建设，包括电子信息资源、数字图书馆建设、馆际互借、文献传递服务、文献资源建设等几方面在理论和实践中的发展和变革；论述了21世纪初网络环境下传统型和现代型两种层次并存的资源共享；探讨了文献资源建设从"拥有"模式到"存取"模式的重大转变、特色馆藏建设和无缝一体的网络信息资源体系的建设途径；较为全面、系统地研究和介绍了网络环境下资源共享的新型组织模式的形成及其特点；强调了文献传递是实现资源共享的关键；并试图准确把握网络环境下资源共享研究和实践的发展趋势。

The development of network and communication technology provide convenient and shortcut approach to exchange information and share resource. On the other hand, there has been the problem how to manage the network since the network appeared. SNMP emerging as the times require with the development of Internet provides the universal methods to get and configure the information of network management from the objects managed. It is a discussable problem how to understand SNMP deeply and apply SNMP to practice effectively.

网络和通信技术的发展，一方面为信息的交流，资源的共享带来了方便、快捷的途径；另一方面，从网络出现起，就存在着网络管理的问题，在Internet发展中应运而生的简单网络管理协议定义了从被管理对象获取和配置网络管理信息的简单而功能强大的通用方法，然而要透彻地理解它和有效地应用于网络管理的实践中是值得研究的问题。
