Based on how routers gather information about the structure of a network and their analysis of information to specify the best route , we have two major routing algorithms and decentralized routing algorithms 人们基于路由器收集来的关于网络拓扑结构和传输信息分析报告来确定最优路由路径，现有两种路由选择算法，基于中心控制的路由选择算法和基于动态分布式的路由选择算法。
By comprehending the theory of computer programmable logic device and comparing of various of cpld structures , we choose flex10k series chip as the central controlling part of data acquisition card , which is theoretically fit for on - site monitoring technology 通过对可编程逻辑器件原理的了解以及各种cpld结构的对比，选取适用于在线监测的flex10k系列芯片作为数据采集卡的中心控制部分。
The chief difference between mobile ad hoc networks and conventional cellular technology is the apparent lack of a centralized entity within an ad hoc network . there are no base stations or mobile switching centers in an ad hoc network 它与传统的蜂窝通信系统之间最重要的区别是前者不需要中心控制的功能实体，网络中没有固定的基站和移动交换中心，因此，所有协议都必须以分布式工作。
The utilization of wind energy which is clean has become more and more important in electric power , in this paper , the electric control system of the large - scale wind turbine generator ( wtg ) is designed and studied , including central control system and grid - connected control system 风能作为一种绿色能源，已经成为一种新兴的重要发电型式。本文对兆瓦级风力发电机组电控系统中的中心控制和软并网两个部分进行了设计和研究。
Internet worms are difficult to eliminate because internet is an open and complex scale - free system , and there are a mass of vulnerable nodes , which are absent of managing and defending . if these nodes are infected with worms , worms will be left on them and may attack the other nodes on internet 网络蠕虫之所以难于控制主要是由于internet本质上是一个开放的复杂巨系统,其结构复杂,缺乏中心控制能力以及其开放性的特征导致存在大量网管层面上的不可控节点。
In the paper we amply introduce the logical structure and design of software and hardware of the virtual multi - channel instrument system for temperature measurement . applying the object oriented programming ( oop ) method , center control module , transmitter demarcating module , channels and scopes module , data collection and process module , data analyze module , data display module , data redisplay module , print module and the other auxiliary functions are designed , which realize the collection , process , analyze and display of the powerful virtual instrument 在本文中，作者详细介绍了虚拟式多通道温度测试仪系统的逻辑结构和软硬件设计，运用面向对象（ oop ）的软件设计方法，通过中心控制模块、变送器标定模块、测温通道和测温范围设置模块、数据采集与处理模块、数据分析模块、数据显示模块、数据回放模块、打印输出模块和其他辅助功能模块的设计，实现了对温度信号进行采集、处理、分析和显示的功能很强的虚拟测温仪器。
The system has ten major function subsystems in common : supplier management subsystem , purchase management subsystem , storage management subsystem , logistics centre control subsystem , production management subsystem , cost accounting management subsystem , manager information subsystem , code management subsystem and information issue subsystem , client and client relation subsystem 系统共有十大功能子系统：供应商管理子系统、采购管理子系统、仓储管理子系统、物流中心控制系统、生产管理子系统、成本核算管理子系统、经理信息子系统、编码管理子系统、信息发布子系统、客户与客户关系管理子系统。
