摘要： 本文结合我国第一颗通信卫星的温度场计算,论述了航天器热计算中的网络分析方法,给出了经过网络修正以后的250个节点的稳态计算结果,并与地面模拟试验的数据以及飞行遥测的数据作比较分析表明,计算偏差绝大部分在2～8℃范围内,此外,对今后的热设计工作提出了几点看法。

Abstract: The paper discusses the thermal network analysis in thermal design of the spacecraft, dealing with the calculation of temperature field of first communication satellite of China, and gives the steady-state temperature of 250 nodes which are corrected. The computing results are compared with the data measured in ground simulation and the data telemetered from orbiting satellite. The results of comparison indicate that the computing deviations are mostly within 2～8℃. In addition, the author proposes few on the further thermal design.
