His discoveries, which won him the Nobel prize, led to the caesium atomic clock and the hydrogen maser.
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。
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 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。
Atomic clocks rely on regular oscillations of caesium atoms to keep time and are extremely accurate.
