摘　　要：高精度的计时工具大多数都使用了石英晶体振荡器,由于电子钟、石英表、石英钟都采用了石英技术,因此走时精度高、稳定性好、使用方便,不需要经常调校。数字式电子钟用集成电路计时时,译码代替机械式传动,用LED显示器代替指针显示进而显示时间,减小了计时误差,这种表具有时、分、秒显示时间的功能,还可以进行时和分的校对,片选的灵活性好。数字时钟是现代社会应用广泛的计时工具,在航天、电子等科研单位,工厂、医院、学校等企事业单位,各种体育赛事及至每个人的日常生活中都发挥着重要的作用。Most high-precision timing tools use quartz crystal oscillator.Due to the use of quartz technology in electronic clocks,quartz watches,and quartz clocks,the timing accuracy is high,the stability is good,and the use is convenient,without the need for frequent adjustment.When digital electronic clocks use integrated circuits for timing,decoding replaces mechanical transmission.The LED display is used to replace the display instead of the pointer display,so as to display the time and reduce the timing error.This meter has the function of displaying the time sometimes,minutes and seconds.It can also calibrate the hours and minutes,and has good flexibility in film selection.Digital clock is a widely used timing tool in modern society.It plays an important role in scientific research institutions such as aerospace and electronics,enterprises and institutions such as factories,hospitals and schools,various sports events and everyone′s daily life.
