In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.

本文系统地介绍了网络安全的概念、OSI及Internet的安全体系结构，并讨论了计算机网络面临的各种安全威胁；内部网络的安全问题是每个建网单位面临的最大问题，可以认为防火墙技术是解决网络安全的一个主要手段，本文研究了防火墙的原理及其实现手段；作为一种主动的防御措施，入侵检测系统作为网络系统安全的重要组成部分，得到了广泛的重视，TDS对计算机和网络资源上的恶意使用行为进行识别和响应，不仅检测来自外部的入侵行为，也监督内部用户的未授权活动；虚拟专用网技术的出现，为实现网络间的连接提供了快速安全但又相对便宜的手段，本文较深入的探讨了实现VPN的隧道技术，并对VPN的概念、功能、实现途径、基本构成、关键技术及发展前景等问题进行了全面论述；数据加密技术是网络安全核心技术之一，本文从数据加密算法、数字摘要、数字签名及数字证书等几方面简要介绍了数据加密技术，并分析用数字证书和数字签名实现网络安全的原理和过程；对安全协议的基本原理、主要特点进行了较为深入的研究，并就网络的安全性问题剖析了三种安全协议：IPsec协议、SLL协议和SET协议。

section summarizes simply innovations and inadequacies in this dissertation,specially,it introduces Lyotardpragmatic thought,who defends the legitimacy of scientific knowledge in using the methods and idea of pragmatics,reinterprets modern scientific crisis,social variation and cultural symptoms,and holds extricating the right of legitimacy from metanarrative ,deciding it through gamers and discourser,then,setting up a foundation for legitimacy of scientific knowledge.This inspires the new study about scientific rhetoric.

结语部分简单总结了本论文在写作上创新的地方和不足之处，特别是着重介绍了利奥塔把语用学的方法和观念运用于辩护科学知识的合法性，用科学知识语用学来重新解释当代的科学危机、社会变异和文化症状，主张把合法性的权利从"元叙事"的束缚中解脱出来，而由游戏者和对话者本人去决定，从而对科学知识的合法性问题进行奠基，这启发了新的"科学修辞学"问题的研究。

Therefore, the following works was conducted: 1 Setting up different types combination failure model of ice sheet interaction with semi-breakwater, and considering different actual conditions of crushing, bending and bucking failure in the process of ice pileup when ice sheet acts on the semi-breakwater; 2 Applying analysis of non-continuous transmutation for the numerical simulation. This method is a new numerical analysis method of simulating mechanics response of dispersoid, it has a broad application prospect for the simulative questions of ice sheet moving, deforming, breaking and circumvolving after ice sheet occur pileup.

I thought once--I meant once to--to make her an offer by and by, when this horrible mystery about George Talboys should have been cleared up and everything peacefully settled--but now-- His thoughts would ordinarily wander away at this point of his reflections, carrying him where he never had intended to go; carrying him back under the pine-trees in Dorsetshire, and setting him once more face to face with the sister of his missing friend, and it was generally a very laborious journey by which he travelled back to the point from which he had strayed.
