氢脉泽是至今为止除极短时间测量间隔之外最稳定的频率标准,它是甚长基线干涉测量仪(VLBI)中的一个关键设备。这篇文章将描述上海天文台为中国VLBI网南山站研制的氢脉泽的性能。
The hydrogen maser is the most stable frequency standard generally available today for all but the shortest measuring time. It's an important subsystem in VLBI. This paper will describe the performance of hydrogen masers used in Nanshan VLBI station.
