摘　　要：对几种抗核爆X射线的防热材料随机产生的Voronoi微结构进行能量沉积计算,得到材料在X射线照射方向不同深度处沉积的比内能,结果表明:相同的X射线照射下,不同参数条件的Voronoi结构能量沉积的平缓程度(即剖面梯度)不同。3种随机Voronoi结构的表征值分别为77.22%,79.56%,84.14%,表明Voronoi多边形结构可提高防热材料抗核爆X射线能力。In this paper,the energy deposition calculation of several randomly generated Voronoi microstructures is carried out to obtain the specific internal energy of the material deposited at different depths in the direction of X-ray irradiation.The results show that the gentle degree of energy deposition,namely the profile gradient is different for Voronoi structures with different parameters under the same X-ray irradiation.The characterization values of three kinds of random Voronoi structures are 77.22%,79.56%,and 84.14%,respectively,indicating the feasibility of Voronoi polygon structure in improving the anti nuclear explosion X-ray capability of thermal materials.
