The next move is to deduce the range of a bombing radiating wavelength with the flying bomb ' s temperature being analyzed and to compute the target ' s irradiance and radiated luminance between spectral penetrating strip based on the planck formula for the black body 在此基础上，从分析飞行弹体的爆炸温度出发，推导了弹体爆炸时辐射峰值波长的范围，分析了黑体辐射的普朗克公式，计算出目标在光谱通带内的辐出度和辐射亮度。
