架空线

Another research topic is evaluated lightning induced voltages on nearby overhead-lines. Lightning is a transient, high-current discharge whose path length is measured in kilometers. During flash, neighbor electromagnetic field change violently, that would induce voltages on close-by metal.

另一研究课题为，非直击雷害造成邻近区域内架空线上的感应电压的探讨，雷击闪络可视为长距离的放电暂态现象，过程中会使得雷击周遭的电、磁场剧烈变动，将会在邻近的金属物件上感应出电压造成二次的伤害。

The array of overhead wires supply power for the electric trolley buses such as the one seen on Stockton Street.

该阵列的供电架空线的无轨电动巴士如看到斯托克顿街。

With the need of the modern city development, at present, more and more the middle-low voltage power supply networks transport the electric power from trolly wire to electric power electric cable.

随着现代化城市建设的需求，目前，越来越多的中低压配电系统由架空线转化成电力电缆输送电能。

On the basis of analyzing and researching the reason of the current leakage with the underground D.

本文分析研究了煤矿井下直流架空线电网产生漏电的原因，总结了漏电保护研究的现状，并在此基础上阐述了基于附加直流电源的煤矿井下直流架空线电网漏电保护的原理。

With the lightning rod, the arrester and the overhead static cable to the transformer substation house, the electrical equipment and the turnover air line make the anti-radar protection, effective had prevented strikes the thunder and the invasion thunder electric wave straight to the power equipment damage.

用避雷针、避雷器和避雷线对变电所的房屋、电气设备和进出架空线做防雷保护，有效的防止了直击雷和入侵雷电波对电力设备的损坏。本设计还对变电所的接地做了说明。

The trolley bus pick s up current from an overhead wire.

无轨电车的电能是通过架空线供给的。

A device used to splice aerial service wire and attached to the aerial wire.

用来接合天线服务线，并与天线架空线相连接的一种设备。

Rationale - routes with overhead wires can be set at different heights (probably not too relevant to UK routes), so different locos look odd if the pantograph is too high (e.g. the Acela is 7.2M the Japan wire height is just over 5M).

基本原理——有架空线的线路可以设置不同高度的架空线（可能跟UK线路不是太有关），因此不同的机车如果导电弓架太高的话看上去会很古怪（比如：Acela机车是7.2米而日本的则是大约5米）。

Main products: aluminum wire cutter,钢芯铝绞线, cables, overhead insulated cables, PVC insulated cables, buried cables, fire-retardant cable.

公司主要产品：铝绞绞线、钢芯铝绞线、电缆、架空绝缘电缆、聚氯乙烯绝缘电缆、地埋电缆、阻燃电缆。

The authors give the definition of insertion loss of electric locomotive in inductive communication through trolley wire in a mine tunnel and compute insertion loss and transmission loss. After contrasting the two losses, we know that the insertion loss is very large and it is necessary to use dedicated induction line.

给出了在矿井中利用电机车架空线进行感应通信时，架空线负载引起的插入损耗的定义，计算了插入损耗和无负载时的电磁波传输损耗并对比了这两种损耗，可知插入损耗是非常大的，这说明了使用专用感应线的必要性。

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。
