研究结果表明：气体动力载荷因素中，压力升高率和放热率是影响燃烧噪声的重要因素。
The result shows that the rate of pressure rise and the heat release are the main dynamic load factor that affects the combustion noise.
因为柯达火药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。
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.
