The invention relates to an arbitration method of exchange network, wherein each input buffer inputs one exchange request to arbitrator; based on exchange allowance, building connection allowance with relative output unit; on the idle input buffer and output unit without connection, arbitrator uses random distribution to build one-to-one connection with all input buffer and output unit.

本发明提供了一种交换网络的仲裁实现方法，该方法中，每个输入缓存每次向仲裁器仅需提一个交换请求，然后根据交换许可与对应的输出单元建立连接认可，对于未建立连接认可的空闲输入缓存和输出单元，仲裁器按照公平性原则，采取随机分配的机制，使得交换网络的所有输入缓存和输出单元间均能建立一一对应的连接。

1、Neural network correlated with LIFG and RIFG exists in normal subjects in resting-state,which might be the neural foundation in retaining the normal language function;2、The left fusiform gyrus,bilateral medial frontal gyrus and right anterior cingulum in aphasia patients after stroke showed low degree correlation,that might be one of the mechanisms of aphasia;3、The brain regions showed positive correlation with RIFG in aphasia patients only exist in right hemisphere in resting-state as well as which exist in bilateral hemisphere in normal subjects,suggested that RIFG is out of correlation with the left hemisphere in aphasia patients;4、The left thalamus showed positive correlation with RIFG only in normal subjects, inferred that the left thalamus might be an important mesomerism structure in the correlation of bilateral hemisphere;5、Left insula showed stronger positive correlation with RIFG in normal subjects than that in aphasia patients,suggested that dominant hemisphere insula is important in retaining in normal language function.

1、正常人在静息状态下即存在与LIFG和RIFG具有相关性的神经网络，该网络可能是维持正常语言功能的神经基础；2、脑梗死后运动性失语患者左侧梭状回、双侧额叶内侧回、右侧前扣带与LIFG的连接程度的减低可能是运动性失语的发生机制之一；3、与RIFG正相关的脑区在对照组为双侧半球分布，而在患者组仅出现在右侧半球，说明患者组RIFG与左侧半球的连接中断；4、RIFG与左侧丘脑的正相关性仅出现在正常对照组中，推测左侧丘脑可能是联系两侧半球功能区的重要中介结构；5、对照组与RIFG正相关性明显高于患者组的脑区位于左侧岛叶，说明优势半球岛叶对维持正常语言功能具有重要作用；第二部分脑梗死运动性失语患者语言恢复机制的静息态fMRI初步探讨目的：运用fMRI技术，采用种子点方法在静息状态下分析脑梗死运动性失语患者不同的恢复阶段语言功能连接方式。

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.

The network is liable to be attacked by the hacker and virus because of the fluidness of information, the distribution of resource, the opening of connection and diversity of connection forms. So the security problem is become more and more serious.

由于计算机网络具有信息的流动性，资源的分布性，连接的开放性和连接形式的多样性等特征，致使网络易受到黑客和病毒的攻击，因此计算机网络的安全问题变得越来越突出。

On the net collect summed up the following respects, offer text to receive the main page on the site repeatedly, according to website size, more or less can webpage numerary receive all pages repeatedly even; For every join provides a brief introduction, in order to hints this one's duty allows the person that visit is about which on one hand; Exceed in website map and text the mainest crucial term alludes inside join, the help searchs theme of page of join of engine identifying place is about which on one hand; Help engine indexes a few dynamic pages, because a few pages will be of dynamic generation, if not be user behavior is called,will not show come, can put this join on website map, in order to help the dynamic page with engine main index; To make website map attracts the visit of network spider, the descriptive sex statement with go up certain must be written to use this connective keyword to have simple description at the back of join, but the use keyword that cannot transfer, can be just the opposite to what one wished otherwise; Because general spider catchs page of before 3 class only, so website map makes the same score better more, what point to here is logical way, is not physical method.

在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。

The data capture mainly gathers the data from the network. Protocol analysis can analyse every segment of the data packet according to protocol standard. Data recover can recover all the data of the application layer of the TCP connection. IP spoofing can construct all kinds of packets and realize the network attack. Real-time interruption can interrupt the TCP connection of Both sides of communication as the third party. Fire wall can realize network access control. Then the system can protect the network information safety from many aspects.
