摘要
本文介绍在某工程上应用的上海天文台工程型氢频标10ms级频率稳定度的改善措施和在采样时间为10ms时,对氢频标频率稳定度测量的结果。
The paper mainly describes how to improve frequency stability of H-maser frequency standard, which is used in the field of engineering, for an averaging time of 10ms at Shanghai Observatory.The result of its frequency stability for an averaging time of 10ms is obtained.
