摘要
本文给出了低空核爆炸缓发γ射线产生的电子生成率的数学表达式,讨论了低空核爆炸冲击波激发的声重力波。在此基础上,进一步讨论声重力波对剩余核辐射引起的附加电离的扰动,计算出了爆心上空附加电离的电子数密度扰动变化曲线。
It's known that additional ionization is made by delayed γ rays released from radioactive debris and that acoustic gravity waves are produced by pressure pulse from a nuclear explosion.In this paper,the disturbance of the additional ionization caused by acoustic gravity waves is studied.The distur- bance curves of the electron density of the additional ionization above the centre of explosion are given.
