The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.
本文的研究工作主要集中在以下几方面:研究了如何利用混沌映射产生置乱矩阵的方法,给出了基于混沌的数字图像置乱方法,该方法能够将原始图像变成面目全非的杂乱图像,从而保护了数字图像的真实内容;研究了灰级混合函数,提出了基于混沌的灰级混合函数,由于该函数具有混沌特性,所以经过该函数处理后的图像具有非常均衡的灰级直方图;针对图像加密的错误鲁棒性与安全性之间的矛盾,提出了一种含有扩散机制的灰级混合函数。

In this paper, we deal with the complete extension of a fuzzy relation and obtain the following main conclusion. Every reflexive,*-antisymmetric and *-transitive fuzzy relation can be extended to a complete reflexive,*-antisymmetric and *-transitive fuzzy relation, namely, every partial order can be extended to a linear order.
文章研究了一个模糊关系的完全扩张问题,主要结果为:一个自反的、*-反对称的*、-传递的模糊关系可以扩张成为一个完全的、自反的、*-反对称的、*-传递的模糊关系,即任何一个偏序都可以扩张成一个线性序。

In the paper, the kinds of reachability notions are defined and charactered firstly in their matrices and graphs. By the discussion of the matrix standard form and its transitive closure, the relation among the maximum partial reachability sets, the standard form of the matrix and its transitive closure are posted and the network partial reachability is based. The standard form provides methods for the improvement of the network reachability.
