双语例句
- When the switch is turned to any of its variable speed "on" settings, current can flow though the switch and down to earth to allow the relay to switch on.
当开关转变为任何变速“开启”的设置时，电流可以通过开关接到地上，继电器开启。 - A new model of the way the Earth interacts with the solar wind indicates that a replacement field will form in the upper atmosphere during the switch.
地球与太阳风互相影响该情形的新模型显示位移区将会在转换期间上面的大气中形成。 - This paper introduces the quick speed transient overvoltage ( VFTO) generated from operation of earth switch in GIS, describes the measurement of VFTO with a calculus system and analyses its result.
介绍GIS内隔离开关操作产生的快速暂态过电压（VFTO），利用微积分系统对VFTO进行测量，并分析其结果。 - Even an AT& T move would likely be seen as "scorched earth" policy as it would encourage other carriers to cut prices and give customers little reason to switch networks but still hurt revenues.
此前AT&T曾鼓励其它的运营商学习自己，降低手机的网络服务费，以保证自己的客户不会转而选择其它的运营商，不过这种做法被业界普遍认为是一种弊大于利的“焦土政策”。 - And we are acutely aware of the dynamics of the Earth wobble, which can switch into and out of an opposition lean quickly as well as go back and forth in a daily polar wobble.
而且我们清楚地了解地球抖动的动力学，不仅会在每天的极性抖动中来来回回，还会转变成快速地向另外一个方向倾斜。 - And to make electric conductor or conductor and the distance between the earth have enough insulation, used for type switch gear and other switchgear inside.
并使带电导体间或导体与大地之间有足够的距离绝缘，用于中置式开关柜及其它开关柜内。 - From the data it can be found that when the fault locates far from the start point, the earth impedance decreases quickly during arc-burning and the zero sequence voltage increases rapidly at the same time, and the relays switch off the fault in time.
在分析过程中发现定子接地故障点离机端近，接地电阻在燃弧过程中很快减小，故障零序电压很快升高，保护也及时切除了故障。 - However, very fast transient ( VFT) process can be produced, during the operating of disconnector switch, earth switch and circuit breaker.
