Under the leadership of the National Headquarters for Earthquake Disaster Mitigation, as of 8:00 on May 19th, the telecommunications sector has sent out 26,000 people for repairing, dispatched 391 emergency telecoms vehicles, 979 satellite telephones, 7422 power generators, over 2000 sets of emergency communications equipment and equipment for repairing, 1000 cells specifically for the satellite telephones and 150 sets of field power supply equipment.

在国务院抗震救灾指挥部的统一指挥下，截至5月19日8时，通信行业已出动抢修人员2.6万人、调动391台应急通信车、979部卫星电话、7422台发电油机、2000多套其它应急通信和抢修设备，1000块卫星电话专用电池，150套野外电源装备，累计调用卫星转发器资源496 MHz，发送应急提示和抢险指导等方面的短信9亿条。

In the self-excited dc machine, the field winding can be connected in three different ways.

对于它励直流电动机，励磁线圈由一个单独的电源来励磁，如图 4-1A-2a 所示。

In the absence of pulse input, the power of incentives in the winding gap magnetic field under the rotor can maintain the original location in the targeted state.

在没有脉冲输入时，在绕组电源的激励下气隙磁场能使转子保持原有位置处于定位状态。

It's a bit easier because you don't have to detect and configure your own hardware. Ironically, it's simultaneously harder because correctly handling Plug and Play and power management is fiendishly difficult.

简单的是您不必对硬件进行测试和配置，但难的是正确处理即插即用和电源管理，而且非常之难。

Finally, a simple principle of choice supply type to heat filament was given.

最后给出了热阴极驱动电源的简单选择原则。

Generally focus on high-voltage switching power supply to check the number of part-to-ground filter capacitor.

一般是重点检查开关电源高压部分的几个对地滤波电容。

If there is enough practical ability, you can try to replace the power supply inside their own filter capacitor, which often can be effective; and if the result is less obvious, can be switch off for.

如果有足够的动手能力，也可以试着自己更换电源内滤波电容，这往往都能奏效；如果效果不太明显，可以将开关管一并换下来。

But not entirely so, some will not be able to enter the protection of the state, which would damage, repair process found in the main power supply filter capacitor is fast rectifier diode breakdown or damage to the majority.

但是也不全是这样，有一部分就不能进入保护状态，这样就会损坏，维修过程中发现主要是以电源滤波电容击穿或者快速整流二极管损坏的居多。

Edge can also try to replace their power within the filter capacitor, which often can be effective; and if the result is less obvious, can be switch off

力，也可以试着自己更换电源内滤波电容，这往往都能奏效；如果效果不太明显，可以将开关管一并换下

In essay, the function of link control is explicated in detail, and how link controller realizes to control the link control devices, for exemple,the defend and arrange cigarette air blower、keep forced draught blower、water pump of fire prevention、spray pump 、rolling screen door of fire prevention and the none power of fire prevention.

论文中，对本工程消防报警系统联动控制的功能有详细的阐述，并结合控制原理框图，说明联动控制器如何实现对防、排烟风机、正压送风机、消防水泵、喷淋泵、防火卷帘门、非消防电源等联动控制设备的控制。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
