| 摘 要： | 为了在月球表面维持航天员本身热平衡，保护航天员不受太阳辐射和月球表面红外辐射的危害，对月球表面航天员与周围介质之间的热交换进行了综合分析，建立了月球表面航天员与周围介质之间热交换的数学模型。计算与分析结果表明：月球表面温度及穿透到航天员的热流随太阳射线的入射角的变化而变化；登月服的吸收系数、辐射系数以及热阻直接影响航天员本身的热平衡。

| Abstract: | To maintain thermal balance of astronaut,and aviod injuries by heats of the solar radiation and radiation from the Moon, a detailed analysis of heat exchange between the astronaut and the entironment medium was made and a mathematical model was established. It indicates that the Lunar surface temperature and the thermal current transmited to the astronaut change with the incindent angle of the solar radiation.The thermal balance of the astronaut is affecded by absorption coefficient,radiation coefficient and thermal resistance. |
