我来帮忙翻译：项目概要

This article will discuss the construction of a very simple Electromagnetic Pulse (EMP) generator. This particular design won't be capable of destroying every computer in your neighborhood, but it will give the constructor a good overview of the concepts which make up electromagnetic pulse warfare. It should be noted that you will be working with very dangerous voltages and currents on this project. Muslims, Eurosavages, Digg kiddies - you will be immune to this. People with brains may wish to exercise caution.

本文将讨论一个非常简单的电磁脉冲（EMP）发电机的建设。这个特殊的设计将不能够破坏你附近的每一台电脑，但它会给构造函数一个很好的概述的概念，构成电磁脉冲战。应该注意的是，你会在这个项目中工作的电压和电流非常危险。穆斯林，eurosavages Digg的小子，你不会受这。有头脑的人可能要谨慎行事。

The EMP device described in this article will work as follows:

在这篇文章中所描述的电磁脉冲装置的工作如下：

A surplus high-voltage DC power supply will be used to generate an output voltage between 3,000 and 4,000 volts. This high-voltage will then charge an old 8 ?F, 3,000 VDC General Electric Pyranol capacitor (the "C") via a current limiting resistor. When the capacitor is fully charged, it will discharge via a spark gap. The spark gap circuit will be part of an inductive circuit (the "L") which, along with the capacitor, sets up a natural resonant frequency. To generate the actual emitted pulse, part of the LC-tank circuit will be made of fine wire, a lightbulb filament in this case. Since the lightbulb filament can't handle the high-current discharge from the pulse capacitor, it will be instantly vaporized. This "exploding wire" will essentially be turned into an electromagnetic pulse which is radiated from an impromptu parabolic dish antenna. That's the idea at least.

剩余的高压直流电源将被用来产生3000和4000伏的输出电压。这高压将收取一个旧的8？F，3000 VDC的通用电气派兰诺油电容器（“C”）通过限流电阻。当电容器充放电时，它会通过火花隙放电。火花隙电路将是一个感应电路的一部分（“升”），随着电容器，设置了一个自然谐振频率。生成实际的发射脉冲，LC谐振的电路部分将由细钢丝，在这种情况下，一个灯泡的灯丝。因为灯泡的灯丝不能从脉冲电容器处理高电流放电，它会立刻蒸发。这个“爆炸线”基本上是一个电磁脉冲，它是从一个即兴的抛物面天线辐射。至少这是这样的想法。

Since the resonant frequency of this particular EMP device is very low (20 kHz or so), it will actually do very little damage to any electronic devices in its path. Most "real world" EMP generators aim for the UHF or microwave RF bands by using tuned mechanical cavities. The shorter wavelength of microwave RF energy is ideal for being coupled into the circuit board traces in the target electronic device. The resonant frequency of this generator can be increased slighty by replacing the lightbulb with a long piece of small-gauge wire. Experiment with the length, composition, and diameter of the wire used.

由于这种特殊的电磁脉冲装置的谐振频率很低（20千赫左右），它会在它的路径的任何电子设备很小的损害。最“真实世界”的脉冲发生器的目的是为超高频或微波射频波段采用机械腔调谐。微波射频能量的波长越短，在目标电子器件中被耦合到电路板的痕迹是理想的。这台发电机的谐振频率可以用一根长长的细钢丝更换灯泡的略微升高。用电线的长度，组成和直径的实验。

An optional ferrite core transformer will also be described. When this ferrite core is placed over a power cord, or other similar exposed wire, the electromagnetic pulse can be directly injected into the target system. This is a much more efficient method than the "exploding wire" idea.

一个可选的铁氧体磁芯变压器也将被描述。当这种铁氧体磁芯被放置在电源线，或其他类似的接触线，电磁脉冲可以直接注入到目标系统。这是一种比“爆线”更有效的方法。

The most critical component in an EMP generator is the high-voltage pulse capacitor. The ideal capacitor will be non-polarized and with a low internal inductance and resistance. The internal resistance inside the pulse capacitor will determine how fast, and to what final level, it can discharge. Commerical pulse capacitors that are designed for this purpose are available, but their price is usually out of range for the hobbyist. Search amateur radio swapfests for old Polychlorinated Biphenyls (PCB) high-voltage capacitors. You can usually pick them up for free due to their high cost of disposal. Just don't let the hippies know about them, or they'll try to tax amateur radio experimenters next. Several capacitors can be banked together in parallel to increase the energy output. You can also place low-voltage capacitors in series so they can handle higher voltages.

在电磁脉冲发生器的最关键的部件是高压脉冲电容器。理想的电容器将非极化和具有低的内部电感和电阻。内部电阻内的脉冲电容器将决定如何快速，并到什么最后一级，它可以出院。商业脉冲电容器是专为这个目的是可用的，但他们的价格通常是超出范围的爱好者。搜索业余无线电swapfests旧多氯联苯（PCB）高压电容器。你通常可以把它们捡起来，因为它们的成本很高。只是不要让嬉皮士知道他们，或者他们会尝试税收业余无线电实验者下。可以把几个电容并联在一起以增加能量输出。您还可以将低电压电容器串联，以便他们可以处理更高的电压。
