摘　　要：为降低燃油箱发生爆炸的风险,需在油箱中设置抑爆系统。咨询通告规定,要计算燃油箱平均氧气浓度,需考虑燃油中的氧气析出。根据不同高度下空气在燃油中的溶解度平衡关系及空气中氧氮分压关系,得出飞机随飞行高度变化氧气析出的计算方法。In order to reduce risk of explosion of fuel tank, an inerting system should be install in aircraft. Ac- cording to Advisory Circular, oxygen dissolved in the fuel releasing to ullage should be considered. This paper gets calculation method of oxygen dissolved in the fuel releasing to ullage according with equilibrium relationship of air inside fuel with different height and pressure relationship of oxygen with nitrogen in air.
