With the rapid development of web-based education , the Network-Based Curricula Resources are also constructed speedily and applied extensively in varied fields of web-based teaching and E-learning .The NBCR is the core and basis of the whole web-based education , but currently NBCR is serious lack of integration and conformity, including low-level construction and underdevelopment , the dissimilitude of standards and technologies , repeatedly projected and created , bad stability of curricula resources system , impedient cross-operation of NBCR , deficiency of outstanding NBCR , etc..

目前，作为网络教育基础与核心内容的网络课程资源缺乏整合的现象普遍存在，不仅造成了大量的人力、物力、财力与教育信息资源的浪费，而且低水平开发、标准各异、稳定性差、重复建设、资源零散、条块分割、共享机制缺乏、互操作不畅、资源保障不力、优质网络课程资源匮乏等不利因素，已经严重影响了网络教学与网络学习的质量与效益。

The main work and innovation of this dissertation are: 1. The network management domain-specific mobile agent system architecture and mobile agent model are proposed and described in details. The lifecycle of mobile agent is described by using state diagram. The layered security model is introduced. The mobility model is distinguished by the complete and partial one as well as the explicite mobility and implicite one. 2. Aimming at the complexity and heterogeneity of the network, the abstract network entity is presented and defined in details. The mobile agent is also classified and studied from the point of the mobile mechinisim along with the resposibility view. The NMBMA, which the main component is ANE, is put forward and described by using organizational, informationl, computational and implementary model. 3. The two architectures, NMBMA and Client/Server-based one, are compared and analyzed quantitatively and qualitatively. 4.

The network is exterior the main factor that the gender is influence network product requirement, preference of people basis oneself selects network product, and the network that chooses a process to affect a product again is exterior sexual size, network product market is so balanced be consumer preference do not move a point.

网络外部性是影响网络产品需求的主要因素，人们依据自身偏好选择网络产品，而选择过程又影响到产品的网络外部性大小，所以网络产品市场均衡是消费者选择的不动点。

Bring forward a kind of learning algorithm fitting on the base of spline function, because the spline function has good flexibility and quadratic smoothing property, the search problem of network weight functions training can be converted into the resoluting extreme value problem of the plurality function through using spline function to represent network input and link weight functions, thus the PNN can be trained with the help of the existing neural network learning algorithms;④build a kind of learning algorithm base on the alternate of Walsh function, the complexity of network computing can be decreased through using the complete orthogonality of Walsh function corollary.

应用结果表明该算法收敛速度快，稳定性好；③提出了一种基于样条函数拟和的学习算法，由于样条函数具有很好的柔韧性和二次光滑性，将网络输入函数和连接权函数用样条函数的形式表示，可把网络权函数训练的函数寻优问题转换为多元函数求极值的问题，从而可借助于现有的神经网络学习算法训练过程神经元网络；④建立了一种基于Walsh函数变换的学习算法，利用Walsh函数系的完备正交性，可大大降低网络计算的复杂度。

Wavelength requirements, fair factor and wavelength reusability of ring and real networks are systematically analyzed under uniform and non-uniform traffic patterns. Numerical results show that the heuristics can achieve a great performance of load balancing and wavelength resources are utilized efficiently.

我们以环形网络和实际网络为例，对均匀和非均匀业务模式下网络的波长需求、网络的均衡因子和波长重用度进行了系统的分析，数值结果表明本文的启发式算法能获得良好的负载均衡性能并有效地利用了网络的波长资源。

Before humanitarian company stands to the stage, a traditional publication orgnaization comes, nature of in the bookshops has see a guest begin clamour to remove again " literature of network of traditional literature bow one's head " argument, deep feeling serves as traditional literature " a large amount of " humanitarian company is met unexpectedly to " fireweed " the network literature of class searchs draft, this kind with " traditional literature and network literature confluence " fall oneself for what conceal the careless root writers that figure just invites a network to go up more be pleased with oneself, saw network literature " hasten of general trends place "" new lineal " the picture that the position is getting consolidating with each passing day.

一个传统出版机构人文社站到了台前来，坊间自然有看客又开始叫嚣起一股"传统文学俯首网络文学"的论调，感慨作为传统文学之"大宗"的人文社居然会向"杂草"级的网络文学寻稿，这种以"传统文学与网络文学融合"为掩饰的自降身段只是让网络上的草根作家们更加沾沾自喜，看到了网络文学"大势所趋"的"新正统"地位正日渐得到巩固的景象。

大体而言，中国网络的问题目前主要表现在如下方面：虚假信息特别是谣言众多，网络暴力盛行，以人肉搜索为典型的网络侵犯私人信息和企业商业秘密现象严重，网络对著作权的侵犯泛滥，网络日益成为违法犯罪的主要隐秘途径，等等。

Then the paper puts forward Industry-University-Institute Cooperation Scale-free Networks' foster mechanism based on the analysis of the function of Industry - University-Institute Cooperation Scale-free Networks from the angles of growth, heterogeneity of nodes, robustness and friability of networks and self-Organization.

然后，本文研究了两源、两宿、单中继的协作组播网络，提出了三种网络编码协议，即非再生网络编码(Non-Regenerative NetworkCoding，NRNC)、复数域再生网络编码(Regenerative Complex FiledNetwork Coding，RCNC)和伽罗华域再生网络编码(Regenerative GaloisFiled Network Coding，RGNC)。

To time;Appear the phenomenon that more than ten a students carry out homology operation in the campus net Central Standing Committee, so consider the control that erupt the information;Student the exploitation network pretends the industry, the teacher wants to be at home to stir the number interview school network, the student status management information delivers on the net, so also want the safety that consider the network, preventing the black a breakage network, student copy homework;Campus net again is tool that teacher to face to the different knowledge level of structure, student with transact the personnel, it help us betterly exaltation teaching level, transact the efficiency with study the interest, so the application should be simple with the management easy line, interface amity, not proper too the profession turns.

校园网的建设主要是为了教学应用，而多媒体辅助教学和多媒体教室是教学应用的核心，在网络建设时应考虑多媒体信息的特点，如信息量大，对时间延迟敏感等；在校园网中常会出现几十个学生执行相同操作的现象，所以要考虑并发信息的控制；学生利用网络做作业，教师要在家拨号访问学校网络，学籍管理信息在网上传输，所以也要考虑网络的安全性，防止黑客破坏网络，学生抄袭作业；校园网又是面向不同知识层次的教师、学生和办公人员的工具，它帮助我们更好地提高教学水平、办公效率和学习兴趣，所以应用和管理应简便易行，界面友好，不宜太专业化。
