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。
