摘要: 本文推导了在低空核爆炸的条件下,瞬发γ光子在源区中产生的电流和电场的近似解析公式,从这些解析公式给出的计算结果可看出,电场的前沿、陡度、峰值数值和半宽度的大小主要取决于弹体释放的瞬发γ光子的强度和时间特性。

Abstract: In this paper approximate analitical formula of current and electronic rield produced by prompt-γ photons are derived under the condition of nuclear airburst.Calculational results from those formula showed that forward position, gradient, peak value and half width of electronic field mainly depend on intensity and time behavior of prompt-γ photons released from nuclear device.

Key words: Nuclear airburst, Prompt-γ photons, Electromagnetic pulse
