根据电离平衡方程组和射线在大气中的能量沉积方程,在完善中性大气层模型基础上,通过数值模拟方法得到了空间核爆炸电离效应的时空分布.数值分析结果表明:低空核爆炸产生的自由电子的密度最大值要高于高空核爆炸;对于瞬发核辐射的影响,低空核爆炸和高空核爆炸有着显著的差异;而缓发核辐射的持续时间、影响范围,高空核爆炸情况要大于低空核爆炸.
According to the equation of energy balance of ionization and the energy deposition equation of ray in the atmosphere, the space-time distribution of ionization effect of space nuclear explosion was obtained by numerical simulation on the basis of improving the neutral atmosphere model. The numerical results show that the free space The maximum density of electrons is higher than that of high-altitude nuclear explosions; there is a significant difference between low-altitude nuclear explosions and high-altitude nuclear explosions for the effect of instantaneous nuclear radiation; while the duration, impact range and high-altitude nuclear explosions of delayed nuclear radiation are greater than Low-level nuclear explosion.
