On conic optimization, we work over some properties of cone and its dual cone, and solve the relations between special cones (obtuse cone, orthogonal cone, superior and inferior obtuse cones) and their dual cones.Furthermore, sufficient and necessary condition under which they exist are proved detailed .

本文围绕锥规划问题，对锥及其对偶锥的性质进行了研究，解决了一些特殊锥(钝锥、直角锥、优劣钝锥)及其对偶锥之间的关系，并对它们存在的充要条件给予了详细的证明。

The harm of worms' outbreak becomes greater and greater. Such make worm detection and defense technology face an increasingly tough challenge. Attack Signature Automatically Generation technology is one of the key technologies, this paper focuses on the ASAG technology for research, its main jobs include: 1）Analyzed the research status of ASAG technology from the overall, described its design goals and evaluation criteria, and the current approaches' limitations is given. 2） After deeply researching and analyzing a various of ASAG systems, a basic framework for the network ASAG system is presented, and the detailed analysis of the main function of the components in the framework is also presented. 3）An attack capture model based on distributed honey-pots system is presented. This mode integrates the anomaly detection which based on the mode of dubiety score in the honey-pots, can do a second filter for the samples in honey-pots, and improve the purity of the samples captured. 4） A simple noise-resilience ASAG algorithm is presented, which used the behavioral characteristics of the worm outbreak to generate efficient signatures of samples in the suspicious dataset, which contains large amounts of noisy data, under the complex environment.

攻击特征自动提取技术是网络蠕虫防御技术的关键技术，本文围绕攻击特征自动提取技术开展研究工作，其主要工作包括： 1）对攻击特征自动提取技术的研究现状进行了综述，介绍其设计目标与评价标准，并指出了现有方法存在的局限性； 2）在深入研究与分析各种攻击特征提取系统的基础上，提出基于网络的攻击特征自动提取系统的基本框架，并详细分析框架中各部件的主要功能； 3）提出了基于分布式蜜罐系统的攻击样本捕获模型，该模型在分布式蜜罐系统的基础上，结合基于可疑度模型的异常检测，对蜜罐中的样本进行二次过滤，较好地提高了捕获样本的纯净度； 4）提出一种简单抗噪的攻击特征自动提取算法，该算法利用蠕虫爆发时的行为特征，在复杂环境下含有大量噪声数据的可疑样本训练集中提取有效的特征，降低对样本纯净度的依赖。

After that comes a potted history of the aftermath of the English civil war, starting with the botched scheming that led the maddeningly duplicitous Charles I to lose not only the military conflict but also his head.

在这之后是英格兰内战余波的简史，这部分内容是围绕一个糟糕的阴谋开始的。正是这个阴谋让口是心非，引发众怒的查理一世输掉了内战，还让他身首异处。

Planets are believed to emerge from the accretion of particles in a disk of gas and dust as they whirl around the star.

PDM provide the way that manages product data by static store and dynamic processing. Product is the key data in PDM, all of other entity data and function set are carried about product. Product described and manage product life cycle from design to over. PDM provide basis service for product management, include details and documents.

PDM系统是企业产品数据管理系统的简称，提供了对企业的产品数据进行静态的存储管理和动态的过程管理的方法，产品是PDM系统的核心数据，所有其他实体数据和功能集和都是围绕产品而展开的，对产品加以描述的同时，对产品从设计到报废作全生命周期管理。
