摘要
氢脉泽在1s到1h的时间间隔提供最好的稳定度。对取样时间大约1h,有用的频率稳定度为4×10^(-16),这使它在频率测量、天体物理、空间技术以及相对论测量上特别有用。本文评述近年来氢脉泽标准的最先进进展,分析和讨论了它的稳定度的基本限制因素,指出成功地得到稳定度的各种途径,介绍了近年来才发展起来的卓有成效的氢脉泽的其它品种,指出了氢标准无论在性能上还是在体积上,无论在地面还是在空间,其应用将有广阔前景。
Hydrogen Maser has very good short term stability. So it is widely used in frequency measurement, astrophysics, space technique, etc. In this paper, an overview on recent development for H-maser are presented and some newly developed types of H-maser are also introduced.
