摘　　要：分析了舱外航天服在轨道空间环境的辐射换热热流。采用蒙特卡罗(MonteCarlo)法,计算了航天服及飞船处于各种相对位置时,航天服对飞船的红外辐射角系数;航天服相对于地球位于各种位置时,航天服对地球的红外辐射角系数;在一定太阳照射方向下,飞船及地球对航天服的太阳反射角系数。与文献数据比较,证明此方法计算舱外航天服空间外热流适用性强,结果准确、可靠,能满足工程使用要求。The orbital radiation heat flux received by the spacesuit used for extravehicular activity ( EVA )is analyzed. By Monte Carlo method, the reflection and infrared radiation angle factors are calculated between spacesuit and spacecraft or earth when spacesuit is located at any position relative to the spacecraft or the earth. It shows that the method is applicable and the results obtained are accurate and reliable as compared with data of References, so as to entirely meet the requirement of engineering application.
