Recently important progresses have been achieved on the study of miniaturized high - performance rubidium atomic frequency standards , along with several patents were authorized at home and abroad 近年来，在小型化高性能铷原子频标研究方面取得重要进展，获得国内外专利多项。
By continuous efforts of many scientists , various kinds of practical atomic frequency standards have been developed , including active and passive rubidium and hydrogen atomic frequency standards 经过几代科学家的努力，已经研制出包括主动、被动型铷原子频标和氢原子频标在内的多种实用型频标。
In the middle eighties of last century , the frequency stability of a rubidium maser reached the highest at that time in the world , and consequently the work won the 1st class national award of science & technology progression 八十年代中期，研制的铷激射器频标稳定度指标创下当时的世界最高水平，荣获国家科技进步一等奖。

The concept of " timing " in the article is not the clock in our ordinary living , but syntheses which is made up of some frequency source in the signal generator ( such as cs atom frequency standard , rb clock & high accuracy quartz crystal oscillator ) which produces the primary frequency , the matching input interface and the matching output interface and controlling circuit etc . for example , bits is a kind of timing equipment , which is used to control the timing of some functions 本文论及的“时钟”概念不是指日常生活中使用的钟表，而是由产生基准频率的信号发生器(如铯原子频率标准、铷钟及高精度石英晶体振荡器等)中的某种频率源以及相配套的输入、输出接口和控制电路等组成的一整套具有特定同步定时功能的综合体。如bits就是一种时钟设备，它提供用在通信系统中控制某些功能的定时的时间基准设备，时钟提供的信号称为基准信号、定时信号或同步信号。
