According to the topology of real network 's not always being close in , an improved disjointing algorithm for calculating the reliability of networks is put forward .

本文针对现实的网络图的非封闭性特点，对计算网络可靠性的不交化算法进行了改进，其主要思想就是根据网络图的最小路集把网络图分解成若干子图，求出这些子图各自的最小路集并对它们进行不交化运算求出所有子图的可靠性，进而求出整个网络图的可靠性。

But at enjoy the convenience that high technology bring at the same time, we need to be awake of know, the safe problem of network also become the network application more and more increasingly and seriously huge bar, the situation that the campus network safety hazes already arrived and must unify the management and resolve thoroughly, only good resolve the safe problem of network, the application of the campus network then can be healthy, high speed of development.

但在享受高科技带来的便捷同时，我们需要清醒的认识到，网络安全问题的日益严重也越来越成为网络应用的巨大阻碍，校园网络安全已经到了必须要统一管理和彻底解决的地步，只有很好的解决了网络安全问题，校园网络的应用才能健康、高速的发展。

但在享受高科技带来的便捷同时，我们需要清醒的认识到，网络安全问题的日益厉害也越来越成为网络应用的巨大阻碍，校园网络安全已经到了必须要统─管理和彻底处理的地步，只有非常好的解决了网络安全问题，校园网络的应用オ能健康、高速的发展。

this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

摘 要：以陕西煤矿瓦斯监测远程联网为背景，研究其联网网络的qos保障策略实现。由于现有的各种qos实现机制无法单独为陕西煤矿瓦斯监测联网网络的qos提供保障，因此在实际应用中必须结合多种机制才能得到较好的qos保障效果。比较了传统ip网络的qos结构体系，通过分析intserv和diffserv两种模型的基本原理、工作方式，并指出其各自的优缺点和网络应用环境，设计了将rsvp协议与diffserv模型相结合来满足瓦斯监测数据传输实时性的要求；针对陕西煤矿瓦斯联网的特性，提出了将tcp拥塞控制算法与ip层拥塞控制算法相结合的算法模型，并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的qos特性。

Must speed up pace intergraded with international market and process of electronic finance,establish and perfect relative policy and law and regulation,cultivate,introduce and make use of professional talent in network computer and management,promote the development and popularity of network trade.

同时，网络贸易缩短了整个经济的中间环节，降低了交易成本，节约了社会资源。一、影响我国网络贸易发展的因素1。基础设施建设不足网络基础建设是制约网络贸易发展的重要&瓶颈&。我国由于在资金、科技、人员等方面投入不足，使其与网络贸易发展相差甚远。

Web-based learning evaluation based on Developmental Assessment Theory will absorb excellent evaluation theory, in virtual of advanced computer and network technology, integrate procedural evaluation and multi-evaluation, emphasize more evaluation subject, multiplicities of evaluation criterion and mode, evaluate the learner's ability, promote comprehensive development.

所以，构建基于发展性评价的网络学习评价系统以及相关的平台是支撑网络学习评价的基础，是构建网络学习系统迫切需要的。本文先对基于发展性评价的网络学习评价进行理论分析，然后对网络学习的发展性评价系统进行研究与设计，把此系统划分为电子测验模块、在线讨论模块、我的学档模块、园丁天地模块。

A recent report by the Internet Safety Technical Task Force says that child exploitation on the Net and elsewhere is worrisome but online social networks, such as Facebook and MySpace, are not to blame for the bulk of it since most reported cases predated their existence.

最近，由网络安全技术任务部门发布的一份报告称孩子对网络和其他方面的利用令人担忧，但是诸如Facebook和Myspace这样的社交网络并不应该为孩子对社交网络的大量利用而受到责备，因为大部分的这类报告在Facebook和Myspace这样的社交网络出现之前就有了。

When network becomes one of intermediaries of literature, its suppositional feature makes it resemble the people grand carnival fancy ball with the dummy, symbolic, and interactive characteristics. Also the hubbub, relaxed liberty, and the vulgar humorous language in network literature manifest its distinct carnival color. Compared with the traditional elite literature, network literature, with gradually richening form, has had the common people consciousness that everybody can participate in; and has had the particularity of desire consumption, and the pursuing of real life.

当网络成为文学的传播媒介时，网络的虚拟性又使得网络文学具备了像民间盛大的狂欢节化妆舞会，具有广场狂欢的虚拟性、符号性和交互性；网络文学的众声喧哗、轻松自由、富有个性的诙谐粗鄙语言等特点更加显现其狂欢色彩；与精英化的传统文学相比，网络文学具备了全民参与的平民意识，具备了大众文化欲望消费、追求现实生活的审美特质，其审美形式也在日渐丰富。

But also is facing some thornier question in the movement,like network audit scope too small, lacks the high quality the auditpersonnel, the software system function are few, the network auditdivulges a secret the event sometimes has and so on, investigates itsreason mainly is the financial network system and the auditingdepartment network construction development is not balanced; Thenetwork audit security waits for strengthens; The high quality auditpersonnel seriously lacks; Lacks outstanding network audit softwareand so on.

但在运行中也面临着一些较为棘手的问题，如网络审计的范围太小，缺乏高素质的审计人员，软件系统功能少，网络审计泄密事件时有发生等，究其原因主要是财务网络体系及审计部门网络化建设发展不平衡；网络审计的安全性有待加强；高素质的审计人员严重缺乏；缺乏优秀的网络审计软件等等。
