多年来，人们一直使用铜芯电缆作为电脑网络的传输介质。

Computers have been talking to each other for years along existing copper telephone wires .

以太网是一种典型的总线型局域网络。其传输介质采用同轴电缆、双绞线，传输速率10bi／s。

Ethernet is a kind of topical bus network , its transmission media is coaxial cable with 10 bps .

针对共享式以太网的介质访问方法以及该方法的弊病，设计了一层基于RTCC协议的网络通信中间件消除传输介质访问冲突，达到实时化改造的目的。

In order to overcome in collision of transport media access , a network middleware based on RTCC protocol should be built up , through which real-time communication can be achieved .

现有的控制网络一般基于有线传输介质，由此带来了地表、墙体布线和网络线路维护等一系列问题，在一些设备需要较大范围移动的场合，固定的线路也给应用带来了很多麻烦。

The existing control networks are usually based on wired transmission medium , so a series of problems such as cable deployment on surface and wall , and the network maintenance . The fixed cables take much trouble to the applications when some equipments needs to move .

网络控制系统是一种以通信网络为传输介质，实现传感器，控制器以及执行器之间数据交换的分布式实时反馈控制系统。

NCS is a distributed real-time feedback control system of realizing the sensors , controllers and actuators to exchange data through a communication networked transmission medium .

网络上交通流的传输依赖于网络的拓扑、传输介质、路由协议以及智能体的性能等。

The transitions in traffic flow networks depend on the network topol-ogy , transmission medium , routing strategies , the performance of agents and so on .
