本文介绍“科学实验二号”卫星温控系统概况,主要是1971年3月发射至1979年卫星坠入大气层的八年多轨道运行的结果。实际运行数据证明,温控系统工作良好,同时也说明设计及试验方法基本正确,特别是副舱Ⅰ所采用的百叶窗主动温控机构及太阳吸热板技术经受住了长期考验。 This article introduces the overview of the “SST II” satellite temperature control system, mainly the result of an eight-year orbit orbiting operation that started in March 1971 and then sank into the atmosphere in 1979. The actual operation data prove that the temperature control system works well and at the same time shows that the design and test methods are basically correct. In particular, the blind shutter active temperature control mechanism and the solar heat absorption plate technology adopted by the sub-cabin I have withstood the long-term test.
