摘　　要：外层空间研究特别是深空探测催生并促进了空间热环境模拟技术的发展。热环境模拟设备用于模拟太空高真空、冷黑、高低温、大温差热变形、太阳辐照等环境。文中综述了国内外主流的空间环境模拟设备,分为热真空试验设备和高低温试验设备两大类,对各自的设计目标、规格型号、真空获得、热沉形式等研制特点以及所能达到的极限高低温、降温速率、温场均匀性等热设计参数进行了比较性的阐述,较全面地总结了空间环境模拟技术的技术发展和现状。Outer space researches, particularly deep space exploration, have created and promoted the development of space environment simulation technologies. Environmental simulators are for obtaining conditions such as high vacuum, cold and dark, solar radiation, high/low temperatures, and thermal distortion by large temperature difference. This paper reviewed the well - known domestic and foreign space environment simulation equipment which were divided two groups namely thermal vacuum e- quipment and high -low temperature chambers. The features of their design objectives, methods of obtaining high vacuum, forms of heat sink and thermal specifications on temperature range, cooling rate, and temperature uniformity etc. were elaborated compara- tively. It provides a comprehensive summary of the development and status of the space environment simulation technologies.
