低空核爆炸引起的低电离层扰动效应 THE EFFECTS IN DISTURBANCE OF THE LOWIONOSPHERE CAUSED BY LOW-ALTITUDE NUCLEAR EXPLOSIONS 李钦 Li Qin Guan Rongsheng Long Xianlin 1 first-author 管荣生 1 龙咸灵 1 武汉大学空间物理系 武汉大学空间物理系 Department of Space physics,Wuhan University Department of Space physics,Wuhan University 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. 低空核爆炸 附加电离 声重力波 电子数密度 Low altitude nuclear explosion additional ionization acousticgravity waves electron density 国家自然科学基金资助的项目 1990-02-01 2021-04-01 2
