The theoretical measurement accuracy could be as high as several picoseconds.

其测时隙的精度理论上可达皮秒量级。

And the process is exceedingly fast: experimental devices have turned electrons on their heads in a few picoseconds (trillionths of a second).

而且整个程序进行得极快：实验用的装置，只消在几皮秒(10 - 12秒)以内，就能让电子转头。

Physicists have no trouble using, on the one hand, picoseconds (trillionths of a second) or even femtoseconds (quadrillionths of a second) to discuss time at the atomic scale.

在讨论原子级别时间的时候，物理学家用起皮秒（百万兆分之一秒）甚至飞秒（千万亿分之一秒）来都没任何不便。这是一方面。
