转换开关

Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal condition.

同时，他们也用于在正常情况下作转换开关之用。

Tofind a target and determine its position,any radar station has to basically consist of a transmitter,a receiver,an antenna,an antenna duplexer,a display and a timer.

为了要发现目标和确定其位置，任何雷达站基本上都必须包括发射机、接收机、天线、天线转换开关、显示器和定时装置。

Four new microwave devices revolutionized radar; the British Magnetron (optimized and fanned out into a family by BTL/Western Electric), the American gas discharge duplexer transmit-receive T-R switch tube, the American advanced semiconductor mixer diode (MIT Rad Lab and BTL/WE), and the American klystron local-oscillator tube.

四种新型的微波装置掀起了雷达发展的革M：英国磁控管（为贝尔电话实验室和Western Electric所改良并发展成为一个大家族），美国的气态双工收发转换开关，美国的先进半导体二极管混频器(MIT 电子实验室和 BTL/WE)和美国的可调速本机振荡管。

It dealt with the operation of Vimanas and included information on the steering, precautions for long flights, protection of the airships from storms and lightning and how to switch the drive to "solar energy" from a free energy source which sounds like "anti-gravity."

它与操作维曼拿有关，包括操纵的资料，对长途飞行的防范，保护飞船免受暴风雨和闪电损害，如何从自由能源中转换开关到&太阳能&上，听起上来就像&反引力&。

它与操作维曼拿斯有关，包括操纵的资料，警惕长时间飞行，保护飞船避免受到暴风和闪电的损坏，还有如何从自由能量来源转换开关，变成&太阳能&，听起上来就像&反地心吸力&。

Its features are improved ergonomics, one-hand actution of the power/brake changeover switch and useof modern terminal technology.

该司机台的特点是改善了司机台的人机工程学、可单手操作牵引制动转换开关和使用了现代化的终端技术。

The main parts of the old transmitter is not required to alter, but single/dual polarimetric switch, power splitter, and phase shifter should be added to the chains after the output of a transmitter.

发射机主体部分在原多普勒水平单偏振模式下不作改动，在速调管放大器高频输出之后增加单/双线偏振转换开关、功分器和移相器。

After supplying power, if steering gear is operated at steering room, please put the conversion switch which positions on the controllable plate at steering gear room to "steering gear room" position, then the steering gears can be operated through turning the wheel.

2.1.1送电后，若要在舵机舱操舵，将舵机舱内控制板上的转换开关放在&舵机舱&位置，扳动舵机舱内操舵手柄即可实行操舵。

I plan on using the generator for power outages and I installed a transfer switch.

我打算使用的发电机，停电我安装了一个转换开关。

The series resonance type fault current limiter has the advantage of simple operating principle and topological structure etc. It may be designed with serial compensation following the condition of the electrical network. However, from the simulation, we draw the conclucion: in the process of restraining fault current after a fault occurrence in electrical network, capacitor and parallel inverter switch will stand for poor working condition.

串联谐振式限流器具有工作原理、拓扑结构简单等优点，并且可以根据需要设计成带串补型，但通过仿真分析得出：其在电网发生短路故障进入短路限流工况过程中，其电容器及并联转换开关将工作在相当恶劣的条件下。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
