摘　　要：利用本文提出的等效物理吸收厚度的概念，计算了弹体内充填炸药、水及空气等介质材料时，受准直γ束照射的流线锥形台柱体所相应的等效物理吸收厚度值。导出了检测炮弹内炸药密度的公式，报道了实验结果。The concept of the equivalent physical absorption thickness r p was presented and defined. Irradiated portion of the cannon projectile by collimated γ ray is a pillar having streamline cone. We calculated the r p values of the pillar which is filled up by medium materials, such as TNT, H 2O and air. The practical formula was deduced for testing local TNT density in cannon projectile casing. The densities of the sections with a shape like a streamline pillar in casing, which was filled up with different materials in turn,have been determined experimently.
