cordite

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

炸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.

因为柯达火在较高压较高速度燃烧，所必须使用一个溢流阀，便当用气少时，能让所产生部分气体排到大气中去。
