| 摘 要： | 为探明阿尔法磁谱仪（AMS）的温度变化规律，并为制定AMS的热控制方案提供指导和依据，推导了AMS重要区域（AMS前方、后方、顶部和左舷）的太阳辐射热流计算公式，分析了这些区域太阳辐射热流随轨道参数的变化，解释了AMS顶部的温度变化和太阳辐射热流变化规律在热控方案中的应用。分析表明在国际空间站（ISS）正常飞行姿态下，AMS前、后方和左舷的太阳辐射热流受太阳光与ISS轨道面的夹角（β角）、ISS与会日点的角距（θ角）和地球阴影区的影响，AMS顶部太阳辐射热流受β角和θ角的影响。得出结论：β角、θ角和地球阴影区均是影响AMS温度的主要因素，各区域的太阳辐射热流变化规律可以作为设计AMS温度控制方案的主要依据之一。

| Abstract: | For analyzing the temperature variation of the Alpha Magnetic Spectrometer (AMS), and guiding the thermal control of the AMS, this paper derives the formulas of solar flux density for the selected areas (the AMS ram, wake, top and port areas), analyzes the variation characteristics of solar flux density of the selected areas with orbital parameters, and explains the temperature variation of the AMS top area and its application in AMS thermal control. According to the calculation, in the normal flight attitude of the International Space Station (ISS), the factors influencing solar flux density are: the solar beta angle (β angle), the angular distance between the ISS and the sun-ISS junction (θ angle) and the Earth shadow for the AMS ram, wake and port area; β and θ angles for the AMS top area. Based on the analysis above, β angle, θ angle and the Earth shadow are the main influencing factors of the temperature of the AMS; and the analysis of solar flux density explains the temperature variation of the AMS and guides the thermal control solution. |
