摘要： 用差示扫描量热计（DSC）测定了空间和地面生长的碘酸锂晶体在-100～350℃温度范围内的比热，据此分别给出了相应的计算比热的经验方程．经验方程计算值和实验值之间的最大百分偏差＜±1％.结果显示，空间和地面生长LiIO3晶体的比热在测量温度范围内无明显差别．

关键词: 比热, 空间材料, DSC, 碘酸锂

Abstract: The specific heat of LiIO3 crystal grown in space and on the earth from --110-350℃ wasmeasured by the DSC method. The fitting equations from experimental data of specific heat weregiven. The maximal deviation of the values calculated by empirical equation from experiment datawas about ±1/%. The results show that the specific heats of LiIO3 crystas grown in space and onthe earth have no obvious differentiation.

Key words: specific heat, space material, DSC, LiIO3
