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。

But about 50 trillionths of a trillionth ( 5 10 - 23 ) of a second later , all the quarks , antiquarks and gluons recombine into hadrons that explode outward into the surrounding detectors 但在兆兆分之50 （ 5 10 - 23 ）秒后，所有的正反夸克与胶子就又重新结合为强子而向外爆发，进入周围的侦测器中。
