In Chapter 2, the learning algorithm of the single-layer perceptron and its limitation are considered firstly.

前馈结构的神经网络是最重要的神经网络模型之一，本文系统地研究了前馈结构神经网络的能力，包括多层感知机和径向基函数网络两部份。

In the Internet supply market, we establish a Bertrand duopoly game model:one Internet Service Provider with flat - rate pricing scheme for its service and the other ISP with two - part pricing scheme- fixed access fee plus usage fee.

在网络供应市场上，我们建立一个价格竞争的伯川德双垄断模型：一个网络提供商对其提供的网络服务采用固定定价，另一网络提供商采用两部分定价策略--固定链接费加使用费。

Network quality of service in future needs to consider the impact of inherent self-similar. Traditional networks ignore this.

将来网络服务质量需要考虑网络业务流自有的自相似性对网络性能的影响，而传统的网络模型未考虑此因素。

Last, we discuss new field about network traffic self-similar applied in network security.

最后，我们对网络流量自相似性在网络安全中的应用这个新的研究方向进行了探讨，根据网络流量的变化直接影响流量的自相似性程度，在入侵检测系统中对网络流量异常引起自相似性变化明显的数据进行研究。

The major contributions of the dissertationinclude:Firstly, research on the impact of self-similar in Ad Hoc network.

通过理论分析解释了Ad Hoc网络中业务具有自相似特性的原因，利用相位法对自相似模型的网络性能进行了理论上的分析，证实了突发特性是影响网络性能的最根本原因，得到了影响网络性能的具体参数。

ABSTRACT Computer network security deals with wide range. For the self-security of computer network information, the transmission security of computer network information and the information security of network host are studied.

计算机网络安全涉及的范围很广，本文从计算机网络信息的自身安全出发，研究了计算机网络信息的传输安全和网络主机的信息安全。

We organize the self-security mechanism of Windows2000 Server, the technology of firewall and network anti-virus system together. We describe the basic theory of the system and provide concrete strategy of the implementation.

通过研究密码技术和防火墙技术等网络安全关键技术，本文给出了青岛检验检疫局网络安全解决方案，将Windows2000 Server自身安全机制、网络防火墙技术和网络病毒防范技术有机结合，对该系统的理论基础进行描述，并对系统的实现做了详细说明。

In allusion to weak point of traditional PID control can't effectively tracking parametric variation of control system ,utilize neural network have predominance that self-study、self-organization、associative memory、concurrent processing and can get satisfactory result in complex control system on the basis of double closed loop,advance apply adaptive linear element network—Adaline network, which has self-learn and self-adjust ability.

在双闭环控制的基础上，针对经典PID调节器不能有效跟踪控制系统参数变化过程这一弱点，利用神经网络具有自学习、自组织、联想记忆和并行处理等功能和对于复杂系统控制可以达到满意效果的优势，提出了采用具有自学习和自适应能力的单神经元网络——Adaline网络，来构成一种神经网络自校正控制器。

Results:①While the score of whole subjective well-being was higher than average, the scores of life satisfaction, positive emotion and negative emotion were lower than average. On the other hand, teenager's internet behavior was on normal level.②There were differences in whole subjective self-being, life satisfaction and negative emotion between internet addiction disorder and non-disorder.③Whole subjective well-being, life satisfaction and negative emotion were all slightly predicted by internet behavior.

结果：①青少年主观幸福感总体水平较高，但生活满意度、积极情感、消极情感水平较低；青少年网络行为处于正常水平；②总体主观幸福感、生活满意度、消极情感在网络成瘾和非网络成瘾之间存在显著差异，但在积极情感维度上差异不显著；③网络行为对总体主观幸福感、生活满意度、消极情感作出显著预测，但预测力较微弱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
