cordite

The stench of cordite and clouds of smoke hung over the hollow.

炸的恶臭和炸硝烟笼罩着山谷。”

Since cordite burns at a greater rate at a higher pressure a relief valve must be used to allow generated gas to escape to atmosphere at times when the demand is low.

因火在较高的压力下以较高的速度燃烧，所以必须使用一个溢流阀，以便当用气少时，能让所产生的部分气体排到大气中去。
