利用空间分划的平衡辐射输运方程, 结合Multi1D辐射流体程序计算了辐射驱动内爆芯部的X光发射空间分布, 计算结果表明：高能X光的发射区域随X光子能量的增大而减小, 低能X光的发射区域随X光子能量的减小而减小。考虑芯部中间区域和芯部边缘区域物质的不透明度, 利用遗传算法计算了芯部的温度空间分布, 并与模拟结果作了比较, 二者的不确定度小于4%。

The X-ray spatial distribution of implosion core zone is calculated with Multi1D and the spatial radiation transport equation. The results indicate that the spatial zone of higher energy X-ray emission is reduced with X-ray photon energy increasing, and the spatial zone of lower energy X-ray emission is reduced with X-ray photon energy decreasing. The spatial distribution of core temperature is extracted by the genetic algorithm, and the results are compared with simulation, with consideration of the opacity of materials in core zone. Their uncertainty is no more than 4%.
