一、前言众所周知,大型地面热平衡试验至今仍然是整个航天器热控制分系统研制阶段的一个不可缺少的重要环节,它既为检验卫星热设计的可靠性提供了实验数据,也为热网络的修正计算提供了必要的数据。但是,这种试验往往需要很长的时间,花费大量的人力、物力,才仅仅得到近似稳定的结果。例如,我国第一颗人造地球卫星“东方红一号”的试验时间,每 I. Preface As we all know, the large surface thermal equilibrium test is still an indispensable and important link in the development stage of the thermal control subsystem of the spacecraft. It not only provides experimental data for testing the thermal design reliability of the satellite, but also provides a correction for the thermal network Calculations provided the necessary data. However, this kind of test often takes a long time and takes a great deal of manpower and material resources to obtain only an approximate and stable result. For example, China’s first artificial Earth satellite “Dongfanghong I” test time, each
