原子氧是影响低地球轨道航天器在轨性能的重要空间环境因素之一，其氧化性对航天器表面材料及舱外组件造成损伤，严重影响航天器在轨寿命。针对此问题提出了一种原子氧仿真分析方法，以此对长期低轨运行的载人航天器模型在轨期间表面遭受到的原子氧累积通量进行分析，仿真结果与NASA实测飞行数据比较，二者吻合很好。本仿真计算方法可用于低轨飞行器原子氧防护设计，仿真结果可作为试验依据。

Atomic oxygen ( AO) is one of the most important environmental factors impacting space-craft performance in LEO space environment .Materials used on the exterior of spacecraft can , in most cases , be eroded away through reaction with AO .The atomic oxygen calculation model of man-ned spacecraft was proposed in this paper to calculate atomic oxygen fluence /flux of different sur-faces.The deviation of the simulation results from the measured data of NASA is negligible , so it can be used as a reference for spacecraft designers .
