以太网

The method of designing an industrial ethernet based process control system and application layer protocal is introduced.

介绍了一种运用工业以太网技术的过程控制系统及其网络应用层协议的设计思想。

The network architechure of control system consists of two layers; The hardware architechure of ethernet node is based on ARM7 core processor; The software architechure is based on uClinux embedded OS; The application layer protocal is customed and is realized by C language.

控制系统的网络架构分为两层；以太网节点的硬件基于ARM7 内核的处理器；软件基于uClinux 嵌入式操作系统；网络的应用层协议自行定义，由C 语言实现。

The StarBook controller provides a built-in star chart for intuitive goto control of the telescope, a searchable library of 22,725 celestial objects, autoguider port for astrophotography, and an Ethernet interface for full remote control capability.

该StarBook控制器提供了一个内置的星图直观转到控制望远镜，搜索图书馆22725天体， autoguider端口天文摄影，和一个以太网接口充分远程控制能力。

Examples of network protocols are Token Ring, Ethernet, and Asynchronous Transfer Mode.

网络的协议有"令牌环"，以太网，异步传输状态等。

电力系统同步相量测量；以太网；异步传输模式；监控系统；相角测量装置

With Asynchronous Transfer Mode, Fast Ethernet, and FDDI, today's network planner has three completely different ways to accomplish essentially the same thing: getting data from one computer to another fast.

有了异步传输模式、快速以太网和FDDI，今天的网络计划人员就有三种完全不同的方法完成一件基本上相同的事情：快速地把数据从一台计算机送到另一台计算机。

The network microcontroller DS80C400 is the core of the network interface board, which implement the connection between the sampling board and the Ethernet. The network interface board sends the audio data sampled by the sampling audio board to the multicast address of the network.

网络接口板以网络微控制器DS80C400为核心器件，主要实现音频采集板与以太网的接口，将音频采集板采集到的各路音频数据发送到各自的多播地址。

This connector is a cylindrical (barrel-shaped) connector used to splice together two lengths of thick Ethernet coaxial cable.

这种连接器是一种圆柱形连接器，用于将两根以太网粗同轴电缆结合在一起。

Its middle-ground price will probably doom it to be an innocent casualty of the Ethernet vs.

适中的价格可能注定它要成为以太网与atm之争的牺牲品。

Its middle-ground price will probably doom it to be an innocent casualty of the Ethernet vs. ATM war.

适中的价格可能注定它要成为以太网与ATM之争的牺牲品。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
