cesium atom 基本例句 铯原子 Unlike pendulums and crystals, all cesium atoms are identical.不同于钟摆及石英晶体的是,所有的铯原子都是一模一样的。 In some of them, the resonant frequency of cesium atoms remains amazingly stable, becoming a pseudo-pendulum capable of maintaining near nanosecond precision.有些原子钟里,铯原子的共振频率极为稳定,功能相当于钟摆,精准度可达奈秒。 |
