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。

2 And 1–7 . Although anteriorly the aorta enters the retroperitoneum at the level of the thoracolumbar vertebral junction, the crura flank the aorta bilaterally, often to the level of the second or third lumbar vertebral body, at or below the level of the renal vascular pedicles.

1–2和1–7，尽管开始主动脉是从胸腰脊椎连接处的水平位置进入腹膜后腔的，但是腕钩从两侧包裹着主动脉，通常要到达第二或第三腰椎体位置，平于或低于肾血管蒂。

Compared to the silk, moisture regains, level dyeing and thermal behavior of raw silk grafted by MA was better. The K/S value increased a little, the fastnesses decreased a little. But the level dyeing of raw silk grafted by EMA declined severely. Compared to the grafted degummed silk, the moisture regains and level dyeing improved a little.

MA生丝增重丝相对于熟丝吸湿性提高、酸性染料染色的K/S值略有上升、匀染性提高、各种染色牢度变化不明显、热稳定性有所提高；而EMA生丝增重丝吸湿性下降、酸性染料染色的K/S略有上升、匀染性变差、各种染色牢度略有下降、热稳定性有所提升。

At the phonological level, foregrounding is fulfilled through the reoccurrence of the identical sound. Nonce-formations, abbreviations, blends and sense-shift attain lexical foregrounding, and the frequent use of the shorts words and numbers also functions. At the syntactic level, foregrounded features are embodied in the frequent use of active voice and quotations, and also the peculiar use of the tenses. Foregrounding at the semantic level principally turns up in the news headlines. It is the use of metaphor, synecdoche, metonymy and pun that helps to bring the potential of the linguistic elements into full play.

从语相层来看，体育新闻报道通过对标点符号的特殊使用、拼写的变异以及排版方式来实现前景化；从音位层来看，前景化靠对同一音素的复现来实现；从词汇层来看，新词的创造、词汇的缩略、混成及旧词新义等实现了对常规语言的偏离，此外，频繁使用短小词和数字也将报道推向前景；句法层上，体育新闻报道则通过对主动语态、引语等的频繁使用和时态的特殊用法来实现前景化；语义层的前景化主要集中在新闻标题中暗喻、提喻、转喻及双关等的使用。

In organization level, design activity fragmentizing strategy and negotiation mechanism are applied to schedule the collaborative design process. To present the uncertainty in design, resource sharing, message passing and real-timed interaction between programs, the integrated control Petri net is adopted to model and simulate the collaborative level. Control level is realized by workflow model, which control the tasks in collaborative design by means of user management, access control and task control rules.

本文通过细化设计活动策略和协商机制，实现了组织级的协同设计过程规划；针对常用的有色Petri网方法不能解决实际系统运行中出现的不确定性、资源共享、信息传递和外部程序的实时交互等问题，通过对有色Petri网的扩充，提出了采用集控Petri网方法，用于协调级的建模和仿真；采用工作流模型为控制级实现，从用户管理、访问控制模型、协同任务控制规则三个方面实现协同设计过程的任务流控制。

In order to facilely perform testing on C or C++ programs, a prototype tool called CppTest is designed and implemented. It can employ three levels'testing, namely (1) structural testing in method level by analyzing program's constructs, instrumenting probes, redirecting I/O stream, etc.,(2) state-based class level testing through modeling state transition behaviors using an extended finite state machine from the class specifications, and (3) system level black-box testing with some traditional strategies such as equivalence partitioning and boundary-value analysis.

以目前普遍使用的C/C++程序作为测试对象，实现了一个能进行方法级、类级和系统级三个级别测试的原型系统CppTest：基于程序CFG图分析、探针插装和I/O重定向等技术，实现方法级结构性测试；按照需求规约运用EFSM对类的状态转换行为进行建模，并依此自动生成测试用例集，实现基于状态的类测试；在系统级别上，运用等价类划分、边界值分析等常规策略进行黑盒测试。
