摘要
高空核爆炸大约有７０％的能量以Ｘ射线形式向外辐射，高能通量密度的Ｘ射线辐照在空间结构物上，在其表面的能量沉积将产生脉冲应力波（通常又称为热击波），这样的脉冲应力波可造成壳体材料的动力学破坏。对于试验研究人员来说希望采用简化解析模型对于其参数作出直观、快速的预测。并以简化模型估算了核爆Ｘ射线谱的特征。
X ray radiation energy in an outer space nuclear explosion is about 70 percent of all the energy.Energy deposition at the surface of a structure material exposed to high fluence X rays will generate pulse stress waves(i.e.thermal shock waves)in the material.The pulse stress waves can cause dynamic damage of the structure material.In this paper,nuclear explosion X ray spectra,initial parameters of the pulse stress waves in aluminium exposed to the X rays and stress wave attenuation along the thickness are estimated by using some simple analytical models.
