有向图

This algorithm has following characteristics: 1 Adopt directed acyclic graph as the basic data structure to deal with more complicated and integrated ontology structure.

算法的主要特点为： 1 采用环形有向图的数据结构，面向更复杂完整的本体结构。

The given matrix A can be regarded as the adjacency matrix of a directed graph.

给出的矩阵 A 可以看作一个有向图的邻接矩阵。

To the adjacency matrix is not necessarily symmetric.

有向图的邻接矩阵不一定对称的。

The Adjacency Matrix of the Directed Graph is easy to build, but the reach-relation of factors is more useful when building the structure model.

有向图的邻接矩阵比较容易建立，但是在建立结构模型时，更有用的是要素间的可达关系。

The main points of this paper are as follows:(1) The actuality and the deficiency of the current workflow technology is analyzed according to the expatiating on the workflow technology.(2) A workflow model supporting the dynamic modifying and its implementation arithmetic and an implementation method using the OO technology is proposed according to the Directed Graph theory.(3) The strategy of dynamic modifying of workflow model is researched, a improved conversion strategy is proposed, and the detailed process of dynamic modifying is discussed.(4) Having researched on the construction scheme of digital campus based on URP and the workflow of office business, an OA system model based on dynamic workflow technology was proposed according to the workflow management system model and several typical functions of OA workflow management system were realized, which is of high value on improving the autoimmunization of business operation and the cooperating work ability.

论文的主要内容如下：(1)通过对工作流技术的全面阐述，分析了目前工作流技术发展的现状和不足，为自己的研究工作划定了问题域范围；(2)利用有向图定义了一个支持动态修改的工作流模型，并给出了该模型的执行算法，给出了该模型利用面向对象技术的一种实现方法；(3)详细讨论了工作流模型的修改策略和方法，提出了一种改进了的转换策略，并给出了动态修改操作的具体步骤；(4)在深入分析基于URP的数字校园建设方案以及办公工作流程的基础上，结合工作流管理系统参考模型，提出了基于动态工作流技术的OA系统模型，实现了OA工作流管理系统中几个典型的功能，对提高业务处理自动化，提高协同工作能力具有重要的应用价值。

In this thesis,we first obtain some sufficient and necessary conditions aboutnormal connected Cayley digraphs,using properties of so called alternating circuit.

本文中，我们首先应用所谓交错回路的性质得到了连通Cayley有向图正规的一些充分的和必要的条件。

有向图有简单的图形表示。

For example, if the two methods used are the Playfair cipher and simple columnar transposition, if transposition is used first, the Playfair cipher can still be attacked, because it takes each input letter to a limited number of substitutes; if the Playfair cipher is used first, multiple anagramming, although now much more difficult, is still possible because a text enciphered by Playfair still has digraph frequencies marked well enough to allow a correct match to be detected.

例如，如果这两种方法用的是playfair密码和简单的柱状移位，如果移位是用第一， playfair密码仍然可以被攻击，因为它需要每个输入信有限数量的代用品；如果playfair密码是用来首先，多重anagramming ，虽然现在困难得多，仍然有可能因为一个文本加密由playfair仍然有向图的频率明显做得不够好，让一个正确的匹配，以进行检测。
