摘　　要：讨论了各有关参数对测定炮弹体内炸药密度的影响。借助于向炮弹壳体内注水的工艺过程、等效物理吸收厚度概念及γ射线透射－注水法无损检测弹体炸药密度公式，测定了弹体内充填不同材料时的密度值。The effects of various parameters on measuring TNT densities in cannonprojectile casing were discussed . The density measurement was performed by using the concept of equivalent , physical absorption thickness, the technological process of floooding water into projectile casing, and the nondestructive inspecting formula deduced on gamma- ray transmission and flooding method .
