What we do at this aspect are : firstly, we describe the permutation symmetry of the structure of some special networks and the corresponding attractor sets with some geometric graphs in euclidean space, which are called attractors graph and geometrized structure graph of the networks respectively ; the geometrizing conditions are also given ; we study the dynamical behavior of the networks using the geometrized structure graph and attractors graph of the network ; moreover, we propose an approach to construct a big - size network with some small - size network with symmetry by the method of direct - sum, direct - produce and semidirect - produce. we also study the dynamical properties " relation between the big - size network and the small - size networks. all those results will provide some theoretical basis for designing a special large - scale network
本文在這方面所做的工作如下：首次將一些特殊網路的結構和吸引子集的置換對稱性用三維歐氏空間中的一些幾何圖來表示，分別稱之為幾何結構圖和吸引子圖；給出了網路對稱性的幾何化條州即相應的對稱性群為可遷群） ：並惜助網路的幾何結構圖和吸弓吁圖分析網路的動力學性質；此外，我們提出了用簡單的具有一定對稱性的小網路按照群的直和、半直積和直積的方式組合成較大的網路的方法，探討了這些小網路和所組成的大網路的一些動力學性質的關系，如穩定態的個數、各穩定態的回憶性質等，為較大網路的設計提供一些理論依據。 -
( 3 ) the inhere drawback of traditional algorithms to construct bayesian networks is pointed out. so the local bayesian network metric attribute based - on bayesian dirichlet metric is also researched, and some notions on bayesian networks are presented, such as comparability, independency and symmetry on nodes etc. it is showed that the comparability is an important factor on whether two nodes is linked, and a sufficient condition for nodes with most comparability is obtained. by using this analysis on local bayesian network, the important principia are presented to create graph models
（ 3 ）由於構造貝葉斯網路圖的傳統演算法存在固有缺陷，本文通過探索貝葉斯網路圖的內在規律，主要研究基於bd度量的局部貝葉斯網路圖的度量屬性，提出網路圖中節點的相似性、獨立性及對稱性等新概念，得出相似性是兩節點連接與否非常重要的因素，對稱節點具有相同的bd度量值，獲得具有最強獨立性節點的充分條件。
