电弧

To improve its reliability, it is necessary to investigate the effects of various factors on the arc moving process, as well as the dynamic change of the whole process from arcing to arc suppressing.

要提高低压电器产品的可靠性，就必须研究各种因素对电弧运动过程的影响，以及从燃弧到灭弧整个过程的动态变化。

But arcing time is very short in the operation of switchgear under the real situation.

在开关电弧燃烧过程中，包含有温度场等标量场，也有流场、电磁场等矢量场。

Secondly all the research works on this project are introduced, including the platform of arcing experiment, hardware system and software.

本文首先介绍了故障电弧保护的发展背景，研究现状和前景，以及立项意义。

The internal arcing faults in switchgear have been paid more and more attention on.

与此同时，我国许多工程，尤其是国家重点工程都对开关柜内部故障电弧提出要求。

Ground-fault protection of low-voltage systems is a considerable problem because of the presence and nature of low-level arcing ground faults.

接地故障的低电压系统的保护是因为存在和电弧接地故障的低级别的性质相当严重的问题。

In the present study, tungsten oxide nanomaterials were synthesized by a modified plasma arc gas condensation technique. The effects of the plasma currents (70~90 A), chamber pressures (200~600 torr), production time（3~12 min）, oxygen partial pressure Ar:O2（1~6:1）and plasma including the hydrogen（0~10 %）on the preparation of tungsten oxide nanostructures were investigated. Pre-treatment on the tungsten oxide nanorods for surface modification was investigated by atmospherical plasma jet. The optical, filed emission, and gas sensing characteristics of tungsten oxide nanopowders were also examined.

本研究系利用电浆电弧气凝合成法来制备氧化钨奈米材料，分别探讨不同腔体压力（200~600 torr）、电浆电流（70~90 A）、制备时间（3~12 min）、氧分压Ar：O2（1~6：1）、电浆气含氢量（0~10 %）对於产物的形貌、相态影响，并使用常压低温电浆设备对氧化钨奈米棒进行表面处理，且针对氧化钨奈米材料的光学、场发射以及使用自行组装气体感测量测设备量测其气体感测特性。

Dark Horse's other songs -- recorded during the summer at Chad Kroeger's converted barn studio in Vancouver -- traverse a wide terrain, from the arcing melodic ebb and flow of the first single,"Gotta Be Somebody" and the metallic groove of "Burn It To The Ground" to the heavy riffery of "Something In Your Mouth" and "The Next Go Round" and the inspiring balladry of "You'll Never Be Alone" and I'd Come For You.

& 黑马的其他歌曲-记在今年夏天在乍得克勒格尔的转换谷仓工作室在温哥华-穿越了广泛的地形，从电弧旋律低潮和流动的首支单曲&爱是要有人&和金属槽的&烧地面&的沉重riffery的&东西你的嘴&和&下一页转到回合&和鼓舞人心的民谣的&你将永远不会被孤立&和&我想现在您。

A buffering agent for a cementitious hazardous waste composition, containing electric arc furnace dust and water, includes dolomitic lime, namely either dolomitic quicklime, dolomitc monohydrated lime or dolomitic dihydrated lime.

用于含有电弧炉灰和水的粘结性危险废弃物组合物的缓冲剂，包括白云石灰，即白云生石灰、白云一水合石灰或白云二水合石灰。

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。
