atomic clocks keep time信息详情
原子钟计时
atomic clocks───原子钟
atomic time───原子钟时间;[计量]原子时间
keep time───使(脚)合拍子;(钟表)走得准
clocks───n.钟表;[仪]时钟(clock的复数);v.为…计时(clock的三单形式)
atomic───adj.原子的,原子能的;微粒子的
keep good time───v.(钟、表)走得准
keep the time───保持时间
keep time for───保持时间
keep time to───抓紧时间
Atomic clocks rely on regular oscillations of caesium atoms to keep time and are extremely accurate.───铯原子的均匀振动记录时间,故而十分准确。
Many computing systems use the Network Time Protocol, or NTP, to keep themselves in sync with the world's atomic clocks.───很多计算系统用的都是网络时间协议(ntp),以保证他们和世界原子时钟是同步的。
That's why we use atomic - or microwave - clocks, which measure the vibration of a caesium atom to keep time, just like the tiny swinging of a pendulum.───这也是我们应用原子钟或微波钟的原因,它们通过测量铯原子的摆动来计时,就像一个钟摆在轻微摆动。
Atomic clocks keep time to better than 0. 01 second a year.───原子钟保持时间准确度一年不到0.01秒的误差。
