The main work and innovation of this dissertation are: 1. The network management domain-specific mobile agent system architecture and mobile agent model are proposed and described in details. The lifecycle of mobile agent is described by using state diagram. The layered security model is introduced. The mobility model is distinguished by the complete and partial one as well as the explicite mobility and implicite one. 2. Aimming at the complexity and heterogeneity of the network, the abstract network entity is presented and defined in details. The mobile agent is also classified and studied from the point of the mobile mechinisim along with the resposibility view. The NMBMA, which the main component is ANE, is put forward and described by using organizational, informationl, computational and implementary model. 3. The two architectures, NMBMA and Client/Server-based one, are compared and analyzed quantitatively and qualitatively. 4. The prototype based on the above NMBMA is designed and some examples are described in the prototype.

主要工作与创新是：提出并详细描述了面向网络管理领域的MAS结构和流动软件代理模型及其内部结构，并采用状态图描述了流动代理的生命周期；提出了层次的安全模型；从数据管理和实现方式两个方面，区分了流动模型即完全流动和部分流动以及显式流动和隐式流动；针对网络的异构性和复杂性，提出了抽象网络实体ANE的概念，并进行了定义；从流动机制和职能两个角度，对流动代理进行了分类研究；以ANE为主要部件，从组织模型、信息模型、通讯模型、实施模型四个侧面描述了NMBMA；定量和定性比较分析了NMBMA与传统的基于Client/Server模型网络管理体系结构；通过一个原型系统的设计和网络管理实例，验证了NMBMA是可行的。

Revolved around the following questions, the part analysis systematically which kinds of ritual is prevailing in the different stages of Shang and Zhou: the standard of classification of rituals recorded by oracle bone inscription, the kinds of rituals in oracle bone inscription, textual and bronze inscription, the degree of factualness recorded in lishu of Eastern Zhou.
