网络规模

• Given the size and the minimum degree of scale - free networks , it is shown that nse reached a minimum value when scaling exponent is about equal to 1 . 7 and the nse increases with increasing scaling exponent after the minimum value
  在给定网络规模及最小度条件下，无标度网络的网络结构熵在标度指数等于1 . 7附近取最小值，即此时网络最不均匀，当标度指数大于1 . 7时，无标度网络的网络结构熵随标度指数单调递增。
• Meanwhile some statistics methods such as , anova and ridge regression were used to discuss the structure , relation types and strength of adolescent social networks , which resulted in great impact on adolescence interpersonal relationship
  本研究结合使用方差、回归等统计分析方法探讨青少年的社会网络构成、社会网络关系类型、社会网络关系力量以及青少年的社会网络规模与关系力量对青少年人际关系的影响。
• In addition , the enormous use of cables in city power system increases the current through the grounded capacitor . these make the single - phase fault current get greater , which lead to more and more instantaneous grounding faults unable to eliminate naturally
  近年来，由于城市配电网络规模的不断发展，以及城网中大量使用电缆，使得系统的接地电容电流大大增加，系统单相接地故障时接地电弧不能自动熄灭，越来越多的瞬间单相接地故障不能自动消除。
• The result of testing the performance of the system indicates that , the time which peers cost on downloading increases very much when the number of the peers increases at a rapid rate in the model of the centralized server , and the performance declines very fast at the same time
  对系统的性能测试表明,集中式服务器的下载方式在节点数激增时,节点下载所用的时间也增加非常迅速,其性能下降也非常快,而livenet在网络规模非常大时,也能保持良好的性能。
• In the same time , implement of qos mechanism will increase the management burden of ip network . it would be too difficult or even impossible to manually configure heterogenous devices with correct queue parameters and traffic processing mechanism to provide consistent qos service in a large scale network
  随着网络规模的不断扩大，通过传统的网管方法配置设备的队列参数、流量调节机制等来保证提供给网络连续一致的qos服务非常困难，甚至是不可能的。
• As computer networks increase in size , complexity and pervasiveness , effective fault diagnosis of such networks becomes more important and more difficult . in order to satisfy the modern network fault diagnosis and elimination , a special tool for the network management operator is required urgently
  当前网络规模曰益扩大，网络结构日益复杂，这些新的变化使得网络故障的诊断变得越来越困难，急需一个工具来为网络管理人员完成网络故障的诊断和排除。
• We designed an integrated system to meet many special requests in the broadband man . there are two main methods for users to connect to the broadband man . the first one is dhcp ( dynamic host configuration protocol ) , which is fit for the ethernet users
  长沙宽带城域网组网主要采用了以太网和adsl (不对称数字用户线)技术，并且网络规模和用户量增长很快，但是在宽带城域网快速建设的同时，在安全管理、用户接入控制和认证计费方面存在许多待解决的问题。
• With the rapid development of telecommunication technology , rapid expanding of the type of telecommunication network and business volume , the size of telecommunication network is becoming larger and larger ; the traditional network management system has not fit itself to the current complex network and has not satisfied telecommunication suppliers ’ needs because of lacking of standard interlinking interface
  随着世界电信技术的飞速发展,电信网络种类和业务量急剧增加,网络规模也越来越大,传统的网络管理系统由于没有标准的互联接口,已经不能适应当前复杂的网络和多样化的电信业务情况下的电信运营商的需要。
• As the higher speed development of the network technology , the larger scale of the network , the more increasing application of the network , it is becoming a huge task and an difficult problem for the network managers how to design and build a network management system adapting to one ' s own local network
  随着网络技术的飞速发展，网络规模的日益扩大，网络应用的不断增加，如何设计和建设一套适合被管网络特色的管理系统已成为网络管理员所面临的一大任务和难题。本文正是基于这样的需求背景和应用特性开展研究的。
