第一章 前 言 §1-1 什么叫内电磁脉冲 核爆炸要产生冲击波、光辐射、x射线、v射线、中子流和碎片流等各种破坏因素,同时还要产生电离层扰动、电子元器件的辐照效应和核电磁脉冲等次生破坏因素.从1972年起美国资料开始发表有关“内电磁脉冲”这种新的次生效应的文章。内电磁脉冲和以往所讲的核电磁脉冲是机理不同的两种次生效应. 在大气层中产生核电磁脉冲的机理有三种。第一种是康普顿电子流或光电子流机理。核爆炸的高能v光子流或x射线在大气中传输时与大气分子发生碰撞,产生康普顿电子流或光电子流。如果存在某种不对称性（例如空气与地面的交界面,大气密度的指数变化等）,则不
The first chapter preface §1-1 what is the inner nuclear pulse nuclear explosion to produce shock wave, optical radiation, x-ray, v-ray, neutron flow and debris flow and other destructive factors, but also produce ionospheric disturbances, electronic yuan Radiation effects and nuclear electromagnetic pulse device secondary damage factors.Since 1972, the United States began to publish information on the “internal electromagnetic pulse” this new secondary effect article. The inner electromagnetic pulse and the nuclear magnetic pulse mentioned in the past are two different secondary mechanisms with different mechanisms. There are three mechanisms for generating nuclear electromagnetic pulses in the atmosphere. The first is the Compton flow or photoelectron flow mechanism. High-energy nuclear v-v photon or x-ray collisions with atmospheric molecules when transported in the atmosphere, resulting in Compton or optoelectronic currents. If there is some asymmetry (eg, air-ground interface, exponential change in atmospheric density, etc.) then
