一个铯钟的工作原理是：将铯原子暴露于微波中，直到它们以一个频率共振，然后以一个相应的周期作为时间度量。
A cesium clock operates by exposing cesium atoms to microwaves until they vibrate at one of their resonant frequencies and then counting the corresponding cycles as a measure of time.
在形式上，一秒钟，或者说一次“滴答声”被定义为在小心受控条件下，微波能量喷发或是铯133原子吸收的9 192 631 770个循环。
One second is formally defined as 9, 192, 631, 770 cycles, or "ticks and tocks," of microwave energy emitted or absorbed by cesium-133 atoms under carefully controlled conditions.
这一获得诺贝尔奖的发现产生了铯原子钟和氢微波激射器。
His discoveries, which won him the Nobel prize, led to the caesium atomic clock and the hydrogen maser.
