Another way to limit I〓 is using fault current limiters , which under normal operation have negligible influence on a power system, but in case of a fault will limit I〓 to several times of the normal current.

限制短路电流的另一方法是在电力系统中加入限流器，它在正常工作状态下对系统无影响，而当发生短路故障时，可以迅速将短路电流限制在额定值的几倍范围内。

The study results had shown that the GPR and magnetic field of grounding system will produce detrimental effects on the breaker control system. Especially, for those poor insulation control lines, large GPR and longitudinal induction voltage during ground fault may lead to flash-over at control line terminals and thus inducing breaker mis-trip out. For the practical case in this thesis, to do well maintenance and to renew those old breakers and control lines with poor insulation situations are very important strategy for preventing breaker mis-tripping. Other protection measures from GPR and magnetic field induction interferences are important too. This study may provide useful information for planning the protection measures.

本研究结果显示变电所接地系统之GPR及其产生的磁场对断路器控制回路确有不利的影响，尤其当控制系统线路及端子若有绝缘不良，在接地故障发生的GPR及磁场纵向感应电压有可能造成闪络而引发断路器跳脱，对於本研究所探讨的案例而言，经由良好的维护或更新那些绝缘情况不良的老旧断路器及其控制线路，对於本研究所探讨的案例相当重要，而做好GPR及磁场感应干扰的防护措施亦相当重要，本研究分析结果可供规则防护措施之参考。

Five suitable load models for the Taipower system are adopted here in order to discuss the effect of the load characteristics on the setting of the overcurrent relay at the time of the incident, as a basis for setting the system coordination:(1) Static ZIP model;(2) Dynamic Motor model;(3) Composite load model;(4) PTI IEEE model;(5) Exponential model.

采用五种适於台电系统之负载模型：(1)静态ZIP模型、(2)动态Motor模型、(3)复合模型、(4)PTI IEEE模型、(5)指数模型，探讨当发生事故时负载特性对过电流电驿设定之影响，以作为系统保护协调设定之依据。

"After installing its preloaded software, the Rebit appliance provides complete, continuous backup of documents, applications, and the Windows XP or Vista operating system -- in short, of the PC's entire C: partition, copying files and folders within moments of editing or recovering a whole system in case of emergency."

在装上它预载的软体后， Rebit 硬碟提供了对於文件、应用软体、Windows 作业系统等的完整的、连续的备份。简言之，整个的C：碟、文件拷贝、文件夹等，在紧急情况发生时，让能够在短时间就做到还原恢复整个系统。

In view of these problems,an intrinsically safe pilot circuit for underground motor intelligent protective systems based on single chip microcomputer is given according to the design specifications of intrinsically safe circuits and the requirements of microcomputer control systems.

井下最大的特点就是存在瓦斯和煤尘，而微机保护系统在发生故障时所产生的电火花或电弧是井下火源之一，因此对于井下电气设备及其控制系统必须采取严格的防爆措施以防止瓦斯和煤尘爆炸。

Introduce and analysed lukewarm the characteristic that controls a system, gave out then the design that gray forecasts ambiguous controller, through Matlab emulation experiment makes clear, when systematic parameter produces change, use this method and photograph of effect of groovy PI control to compare, having better control precision and dynamic character, to actual constant temperature control has certain direct sense.

介绍和分析了温控系统的特征，接着给出了灰色猜测模糊控制器的设计，通过Matlab仿真试验表明，在系统参数发生变化的时候，采用此方法和常规PI控制效果相比，具有着更好的控制精度和动态特性，对实际恒温控制具有一定的指导意义。

Therefore, the need for a gasoline engine when to control the spark plug ignition system. This system requires an accurate control of spark plugs and spark discharge energy of the moment, be able to ensure the normal gasoline engine. gasoline engine fuel supply system and ignition system is a high proportion of the gasoline engine fault location.

因此，汽油发动机需要一套控制何时让火花塞工作的点火系统，此系统必须精确控制火花塞放电的时刻和火花能量的大小，才能保证汽油机的工作正常，汽油机的燃料供给系和点火系是汽油机上发生故障比例较高的部位。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
