摘　　要：针对双头枪弹的特点 ,概要描述了双头枪弹完整的内弹道过程 ,提出了双头弹的内弹道计算假设 ,应用文献 [1 ]所建立的双头弹内弹道计算方程组当某 1 2 .7mm双头弹装填条件——质量、质量匹配、装药量、起动压力和药厚等变化时对内弹道性能参数的影响进行了比较分析 。An interior ballistics process of duplex ammunition is described in general in light of its characteristics. Computational assumptions of duplex ammunition have been presented. With the aid of the interior ballistics computational equations of the cartridge built up in reference [1], the laws of changing in chamber pressure and velocity of 12. 7mm duplex ammunition have been obtained. The effect of loading factors such as the mass of bullets, the matching among the propellant masses, the starting pressure and the propellant powder density etc. on the interior ballistics characteristics has been analyzed in detail. Some important conclusions have been obtained.
