摘要: 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，从而建立了大气层外核栏截X射线辐射场特性的数学模式。

Abstract: 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.
