摘　　要：火药能量的大小与硝化棉含氮量的高低有着直接关系。硝化棉是火药中的主要能量来源之一。由于火药在贮存过程中的不断分解,使硝化棉含氮量逐渐减少,能量下降,机械强度降低和弹道性能变坏,用龙格氮量计法测定库存火药中硝化棉的含氮量具有重要意义。Energy from the gunpowder has a direct relationship with the nitrogen content of nitrocellulose.Nitrocellulose is one of the main sources of energy in the powder.With the continuous decomposition of gunpowder in the process of storage,the nitrogen content of nitrocellulose reduces gradually,the energy declines,the mechanical strength reduces,and the ballistic performance deteriorates.So it is very important to measure nitrogen content in nitrocellulose of gunpowder by Runger＇s method.

关 键 词：龙格氮量计 硝化棉 含氮量
