大气层外核爆炸X－射线辐射场特性研究

RESEARCH ON X RAY RADIATION FIELD WHICH IS FROM A OUTER SPACE NUCLEAR EXPLOSION

Ｘ射线被认为是大气层外反导栏截武器的主要破坏因素。在航天器结构材料的辐射损伤计算中，需要核爆炸Ｘ射线辐射场的数学模式。从Ｐｌａｎｃｋ黑体谱出发，提出按温度梯度分层的归一化黑体谱组合模式，给出Ｘ－射线的释放能量及辐射脉冲。

X ray is regarded as the main damage factor of nuclear interception in outerspace.A mathematical mode of X ray radiation field which is from a nuclear explosion is needed in the spacecraft radiation damage calculation.According to Planck blackbody spectrum,we proposed a compound mode of normolized blackbody spectrum which was stratificed on the basis of temperature gradient,obtained the release energy and radiation pulse and found a mathematical mode of X ray radiation field which is from a nuclear interception in outer space.
