摘要： 当空间飞行器受到碎片的碰撞时，其壳体中会产生冲击加热。文章概述了计算冲击温度的三种基本方法；计算了铁的冲击加热温度，并与实验测量值作了比较。结果表明，利用三项式物态方程计算的冲击温度与测量值符合得比较好。另外，还对影响冲击温度计算值的若干因素进行了分析

Abstract: When a spacecraft under impact of debris,its shell will be shock heated.In this paper,three basic methods to calculate shock temperatures are described briefly.Shock temperatures for iron are calculated and the results are compared with those obtained from experiments.It shows that the results calculated by using three-term equation of state are in good agreement with the experimental results.In addition,the influence of several thermal physics parameters on the calculated value of shock temperature is discussed.
