标准精密钟检定的主要內容,是試驗其钟差,以便得出质量指标。为此,必須获得精密钟每天在同一时刻上的示值或改正值。为了确定标准精密钟的示值,比較簡单和方便的办法是接收各无綫电授时台发播的科学式时号来进行測定。我們知道,一般精密钟的秒針每隔0.5秒跳跃一次。而科学式时号是每分钟有61个音响的时号,它的重复 The main content of the standard precision clock test is to test the clock to get the quality index. To do this, you must obtain the precision clock every day at the same moment of indication or correction. In order to determine the indication of a standard precision clock, a simpler and convenient solution is to receive the scientific time code broadcast by each radio time station. We know that the second clock of a typical precision clock jumps every 0.5 seconds. The scientific-style number is 61 audio per minute, its repetition
