摘要： 采用航天器热控系统设计中常用的热分析计算方法——节点网络法，对一航天器实验模型进行了温度计算，并将计算结果与实验数据进行了比较。采用修正后的网络系数，大部分仪器温度计算值与实验值差值的绝对值在３℃以内，少数在３℃～５℃之间，极个别超过５℃。

Abstract: On basis of a general method for designing spacecraft thermal control system,thermal network analysis method,calculated the temperature field of an experimental spacecraft,and the results were compared with the experimental data.The difference between calculation results and experimental data of most equipment temperature is less than 3℃,a few is between 3℃ and 5℃,and few than 5℃ after thermal network correction.
