The thesis introduces the concept and evolution of NC at first, and analyzes the difference of between NC and PC, diskless workstation, and discusses emphatically the characteristics and applications of NC network architecture, then introduces the definition, the mission and the function area of network management, analyzes a few architecture of network management, and goes deep in to study Simple Network Management Protocol.

论文首先介绍了NC的概念及其发展过程，分析了NC与PC、无盘工作站的区别，重点讨论了NC网络体系结构的特点和应用。然后介绍了网络管理的定义、任务和功能域，分析了现有的几种网络管理的体系结构，并深入研究了简单网络管理协议。

It is researched that the high rate of network addiction in teenagers is caused by special character of their physiological and psychological development. That the teenagers have not been well grown-up in both body and mind, their self-cognizance and interpersonal relation is changeable, the internet has great attraction, and the government is nonstandard and lack of control to the network makes teenager easily enthrall in internet. It is also researched that it is the complex factors which leads teenagers network addiction.

研究认为，青少年成为网络成瘾的高发人群，是与青少年身心发展的特殊性有着密不可分的关系，青少年时期正是人生处在生理和心理都尚未完全发育成熟的特殊时期，他们的自我探索与认同、人际关系等也都处于不断变化之中，再加上网络本身所具有的吸引力，以及政府对网络管理的不规范和严重缺位，这很容易造成青少年在面对网络时出现过度使用和迷恋现象。

Chapter 2, it brings forward the existing problems of network virtues, elaborates the four immoral netork phenomena, including multi- communication and value lose, electronic opium and network enthrallment, false communication and split personality, analyses the reasons why netizen group are absent from morality, and then put forward the major reason, which lies in netizens themselves.

第二章提出了网络道德中存在的问题，阐述了海量信息与价值迷失、电子鸦片与网络沉迷、虚拟交往与人格分裂、黑客病毒与网络攻击四类不道德的网络现象，分析了网民道德缺失的原因，提出最主要的原因还是在网民自身。

Therefore ACDC improves the average network throughput and decreases packet delay of storage network and solve the problems in traditional TCP congestion control, such as low use rate of network bandwidth, worse equability, congestion synchronization and worse adaptability of burst data flow.

在分析和研究主动网络技术的基础上，提出了基于主动网络技术的缓存模型，通过在主动网络节点中预取和缓存用户的访问数据，充分地利用网络资源，提高全局命中率，减小访问时延。

In this paper chip shapes were recognized by using of radbas neural network. We put forward area ratio feature, Euler number feature, etc. geometry feature of chip shape image and thing of those features as inputting vector of neural network. Adopt radbas neural network and training the network using RLS.

研究了径向基函数神经网络在硬质合金刀具切屑形态图像识别中的应用，提出了面积比、欧拉数、分散度等硬质合金刀具切屑形态图像的几何特征，以上述特征作为神经网络的输入矢量，利用径向基函数网络，采用了递推最小二乘法训练该网络。

Through analysing muddleheaded time alignment, build the network of the 3 make a present of before the layer that has many concealed node, be based on extensive to change a gender to consider to use lop algorithm to train, in node of concealed of part of the expunction on the foundation that assures to forecast precision in order to reduce network complexity, the overall situation that uses genetic algorithm to have searchs actor ability to train a network afresh, benefit appliance has algorithm of BP of the local ability that find actor to train this network again.

通过分析混沌时间序列，建立具有多个隐节点的3层前馈网络，基于泛化性考虑采用剪枝算法练习，在保证猜测精度的基础上消去部分隐节点以降低网络复杂性，利用遗传算法具有的全局寻优能力重新练习网络，利用具有局部寻优能力BP算法再次练习该网络。

On the basis of introducing the distributions theory, the paper tells the actuality of the development of Internet distribution channels, and many problems of the development of Internet distribution channels are analyzed. Such as the quality of products, after service and security of a deal cannot be safeguarded, logistics often drop behind. The paper also gives some advices from enterprise interior and enterprise exterior angle, for example, the government should intensify legislation, a company can potentiate its safety management, which will help enterprise adapts the network time competition.
