查询词典 electromagnetic pulse

It stands for Electromagnetic Pulse, and it disables all active electronic devices in the area.

它是一种电磁脉冲，能在一定范围内使任何启动的电子设备瘫痪。

If the resistance rises to the pre-set number(1245－1470Pa), the controller will send out signals, first to control the lift valve to do these operations: close the hole of the valve board to cut air current and stop filtering, and then to open the electromagnetic pulse valve to blow compressed air whose pressure is 0.5-0.7Mpa into filter bag with a short time(0.01－0.12s).

当含尘烟气由进风口进入灰斗以后，一部分较粗尘料在这时由于惯性碰撞、自然沉降等原因落入灰斗，大部分尘粒随气流上升进入袋室，经滤袋过滤后，尘粒被阻留在滤袋外侧，净化的烟气由滤袋内部进入箱体，再由阀板孔、出风口排入大气，达到收尘的目的，随着过滤过程的不断进行，滤袋外侧的积尘也逐渐增多，从而使除尘器的运行阻力也逐渐增高，当阻力增到预先设定值（1245－1470Pa）时，清灰控制器发生信号，首先控制提升阀将阀板孔关闭，以切断过滤烟气流，停止过滤过程，然后电磁脉冲阀打开，以极短时间（0.01－0.12s）向箱体内喷入压力为0.5－0.7Mpa的压缩空气，压缩空气在箱体内迅速膨胀，涌入滤袋内部，使滤袋产生变形、震动，加上逆气流的作用，滤袋外部的粉尘便清除下来掉到灰斗，清灰完毕之后，提升阀再次打开，除尘器又进入过滤状态。

There's no venturi tube in the mouth of bag or blowing tube, that reduces working resistance and makes examining and repairing easy. Electromagnetic pulse valve is of these characters: be sensitive to control, high efficiency, long life span and so on.

滤袋上口不设文氏管，也没有喷吹管，降低了工作阻力，使检修、维护都相当简便，电磁脉冲阀具有控制灵敏、效率高、寿命长等特点。

Simulation of electromagnetic pulse coupling with computer box.

The various functions of the apertures are essential to the shielding box. Electromagnetic pulse couples into the shielding box through the "back-door coupling", which inevitably interferes with or damages the electronic components used in the shielding box.

而屏蔽机箱上各种功用的孔缝是必不可少的，电磁脉冲通过&后门&耦合进入屏蔽机箱，并对其内的电子元器件进行干扰或毁伤则是不可避免的，也是电磁脉冲进入屏蔽机箱的重要途径之一。

The measuring systems are successfully used in the electromagnetic pulse measurement generated by impulse voltage discharge and switch operation in 500kV substations. Full waveforms of transient electric field, transient magnetic field, transient voltage of high frequency relay channels and low voltage alternative current power during switch operation period have been obtained, and the fast transient pulses in high frequency relay channels and AC power have been caught.

将该套测量系统成功地应用于500kV变电站开关操作产生的电磁脉冲的研究中，得到了开关刀闸操作时暂态电场、磁场、高频通道、交流电压等的完整波形，发现低压交直流电源系统和高频保护通道中存在非常严重的脉冲群干扰，初步解释了变电站二次电源模块经常损坏和高频保护经常误动的原因，提出了加强保护和研究的建议，进一步验证了测量系统的先进性。

In order to cover the shortage of the current antenna for high power microwave weapon, the idea of a magnetized plasma channel used as antenna for radiating electromagnetic pulse is proposed. The normal modes of Magnetized Plasma Channel Antenna in lossy gas are analyzed. The concrete realization method of MPCA is simply described. The geometric-model of MPCA is created based on the operating principle of the antenna.

摘要该文针对现有高功率微波武器辐射天线的不足，提出了将磁化等离子体通道用作电磁脉冲辐射天线的思想——磁化等离子体通道天线，分析了MPCA周围为有耗气体媒质时MPCA所传播的一般模式。

According to Andy Mazzara, the director of the Institute for Non-Lethal Defence Technologies at Pennsylvania State University, prototypes of such devices use a laser to create an ionised channel of air through which an electromagnetic pulse is directed.

根据在宾夕法尼亚州立大学非致命性防卫技术学院主任Andy Mazzara的研究报告，这些设备的原型使用的是一束激光光束，通过电磁脉冲的指向，来创造空气中的离子通道。

Objective: To study the protection effect of metal net-like defense cloth in vivo and genistein on Jurkat cell after electromagnetic pulse .

目的 利用在体动物模型研究镀铜织物 EM-4屏蔽布对电磁脉冲辐照后免疫组织的防护效果，并在离体 Jurkat 细胞损伤模型上探讨药物防治的可能性。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
