摘　　要：通过研究建立船用舱室超压的原理,推导舱室增加的空气质量的计算公式,分析两种舱室空气输入形式和空气泄露形式,得到节流阀开口面积与超压目标的特性关系,指出通风机的选型原则和缩短超压建立时间的方式。Based on the theory of establishing overpressure in deckhouse is introduced,the formula to calculate the added air＇s mass is deduced. The two forms of air＇s input and leakage are analyzed to find out the relationship between leakage area and overpressure objective. The principle of selecting ventilator and the method to reducing the time of establishing overpressure are indicated.

关 键 词：舱室超压 输入形式 泄露形式
