摘　　要：铷原子钟的温度系数是决定其长期频率稳定度的关键因素,物理部分的温度系数又是铷原子钟温度系数的重要组成部分。为了改善物理部分的温度系数,在理论分析的基础上开展了试验研究,结果表明:提出的改善物理部分温度系数的措施是有效的。这对于进一步提高星载铷原子钟频率稳定度具有积极作用。Temperature coefficient of rubidium atomic clock is key factor that has important influence on its long term frequency stability. Temperature coefficient of physics package is important part of Temperature coefficient of rubidium atomic clock. For improving temperature coefficient, analyzes some reasons and takes some experiment. Experiment results verify these ways that can really improve tem- perature coefficient of physics package. The work will be useful to improving frequency stability of space borne rubidium atomic clock
