摘　　要：国际空间站轨道平面与太阳光线的夹角(β角)以及空间站右舷侧散热板的固定角度(γ角)是影响阿尔法磁谱仪局部温度的两个重要外部环境因素。本文计算了右舷侧散热板对阿尔法磁谱仪的辐射角系数与β角和γ角的关系,得到了在任意β角下,右舷侧散热板对阿尔法磁谱仪反射太阳辐射热最高效率的,y角。基于计算结果,分析了γ角对穿越辐射探测器气体循环箱温度的影响,并提出了相应调节的机制。下层飞行时间计数器以及WAKE主散热板也受到γ角影响,温度对比发现这种影响符合关于热辐射反射效率的计算。There are two important environmental factors for the local temperature of the Alpha Magnetic Spectrometer(AMS),they are the angle between the orbital plane of the International Space Station(ISS) and the solar vector(β angle),and the position of the ISS starboard radiator(7angle).In this paper,we obtained the relationship between radiant angle factor and the two angles by calculation,and got the 7 angle at which the ISS starboard radiator panel can reflect solar radiant heat to the AMS with the highest efficiency at specific j3.Based on the calculation,we analyzed the impact of adjusting the 7 angle on the temperature of the gas circulation box of the transitional radiation detector,and proposed corresponding thermal-control scheme.The photomultiplier tubes in the lower time of flight counter and the main wake radiator of the AMS can be affected by the 7angle,relative comparison of temperature on the two components presents that the affection on them confirms to the calculation.
