This paper mainly studies the distribution of the electron density produced by the high-altitude nuclear burst in atmosphere and gives part o the results at low-altitude.
本文主要研究高空核爆炸在大气中产生的电子密度分布，同时给出低空核爆的部分结果。
Initial nuclear radiation will be a significant hazard with smaller weapons, but the fallout hazard can be ignored as there is essentially no local fallout from an air burst.
相比小型武器，早期核辐射的危害是很严重的。但是放射性尘降的危害可被忽略，因为空中爆炸基本上不会给地面带来尘降。
If the burst is shallow enough to penetrate the surface, blast, thermal, and initial nuclear radiation effects will be present, but will be less than for a surface burst of comparable yield.
如果离地面够浅以致能穿透表面，那么将出现冲击波、热辐射以及早期核辐射作用，但是作用效果要小于近似当量的地面爆炸。
