研究了片状随行装药火药与不同粒状主装药匹配时的弹道效果，并进而研究了片状火药装药的压力、速度温度系数．结果显示：片状火药是一种燃烧性能和弹道性能都比较稳定的火药，它的合理使用能在最大膛压基本不变的情况下，使弹丸初速获得较大幅度的提高。
The ballistic effect of patchy gunpowder when matched with different granular main charge is studied, and the pressure, velocity and temperature coefficient of patchy gunpowder charge are studied. The results show that flaky gunpowder is a kind of gunpowder with relatively stable combustion and ballistic performance, and its reasonable use can make the muzzle velocity to increase greatly under the condition that the maximum chamber pressure is basically the same.
