以太网

According to production need of certain plant, this paper introduces a networks structure of combining Ethernet with other field control networks.

在本论文中介绍了结合某厂的生产需要，搭建了一个以太网与其它现场控制网络混合控制的网络结构。

However, if auto-negotiation is disabled or not supported, the duplex must be set by auto-detection or manually on both the switch port and the device to prevent duplex mismatch, a common cause of problems with Ethernet (the device set to half-duplex will report late collision s and the device set to full-duplex will report runts).

交换网络典型的使用星型拓扑，尽管设备工作在半双工模式是仍然是共享介质的多结点网。10BASE-T 和以后的标准是全双工以太网，不再是共享介质系统。

As repeaters, thereby extending the distance of your Ethernet network.

因此你的以太网络扩展的距离

Note it is also possible to connect many wireless repeaters to the network via Ethernet cable then they broadcast the signal.

请注意，也可以连接多个无线中继器到网络，然后通过以太网电缆广播的信号。

Ethernet is an ideal platform for constructing elevator monitoring system.

以太网是构建电梯监控系统的理想平台。

Ethernet inter-working model based on pseudo wire in T-MPLS layer network;2. However,traditional LDP based VPLS can not be deployed in large-scale networks due to the full mesh connection problem of pseudo wire .

它的主要思想是在MPLS网络中利用LDP建立和维护以太网伪线，并基于伪线将多个局域网两两互连成一个VPLS网络。

With Nortel's 800-watt Ethernet Routing Switch 10 Unit, up to four failed network devices can simultaneously receive RPS support.

与北电的800瓦以太网路由交换机10个供电单位，多达四个失败的网络设备可以同时接收退休保障计划的支持。

According to introducing, net of aether of operation business class is the good foundation of the framework of base of return trip line that is a center with IP.

据介绍，运营商级以太网是以IP为中心的回程线路基础架构的理想基础。

The realization of a networked small-scaled DCS is proposed.

然后融合三种网络控制系统的特点，结合实际项目——网络化小型集散控制系统的具体实现，给出一种基于交换以太网的全分散控制系统模型。

This paper introduces the hardware configuration and the software achievement of monitoring and control system based on mixed model of industrial Ethernet for sewage disposal.

摘 要：介绍了基于工业以太网混合模型的污水处理监控系统的硬件配置及其功能的软件实现。

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。
