随着数字技术和数字显示器件的发展,数字式石英电子钟在近几年得到迅速发展,并且扩展到日常生活中,除了可做为日常计时用外,并能做为母钟,或做定时自动控制等使用。试制的数字式电子钟的石英晶体采用国产ZB—3型石英晶体振荡器,它可工作在-40℃至+70℃的环境下,稳定度5×10~(-6),保证 With the development of digital technology and digital display devices, the digital quartz electronic clock has been rapidly developed in recent years and has been extended to daily life. Apart from being used as a daily clock, it can be used as a master clock or as a timing Automatic control and other use. Trial production of digital electronic clock quartz crystal using domestic ZB-3-type quartz crystal oscillator, which can work in -40 ℃ to +70 ℃ environment, the stability of 5 × 10 -6, to ensure
