摘　　要：粒子激发X射线谱仪(APXS)是我国嫦娥三号任务巡视器上4个有效载荷之一,它通过携带的主动激发源激发月岩或月壤中的元素,并探测其产生的特征X射线,从而获得月球元素的种类及含量信息.根据APXS所处的极端温度环境,在有限的资源约束下,进行了月夜生存装置RHU的设计分析并开展了相应的结构力学、月夜生存摸底试验.最后,介绍了发射塔架RHU换装的情况与在轨初步探测结果.The Active Particle X-ray Spectrum （APXS） is one of the 4 scientific payloads of Chang＇E-3 （CE-3） Lunar Rover, of which the scientific object is to identify the elements of lunar soil and rock samples. In this paper, the moon-night temperature of the moon surface will be described, and due to the cold environment the APXS will undergo after its landing. Thus, a specialized instrument which is named the moon- night survival device using the Radioisotope Heat Unit （RHU） as its heater source is designed to ensure APXS storage temperature requirements with limited sources on the satellite. In the end, a series of environmental tests are performed, and the installation of RHU on the launch tower as well as the status of the APXS working on orbit is presented since its launching in 2013.
