如此极其精确的时钟是建立在单一铝离子的快速振动，铝离子就是包含在真空中受电磁场约束的失去一个电子的原子。

Such ultra-precise clocks are based on the quick vibrations of a single aluminum ion, an atom that has lost one electron, held in a vacuum and confined by electromagnetic fields.

这个理论附属于量子力学，预示着即便在空间真空中粒子仍快速出现、消失，并由此产生能量。

The idea is tied to quantum mechanics, which predicts that even in the vacuum of space, particles are constantly winking in and out of existence, generating energy.
