One way to do this is to confine the anti-atoms in an inhomogenous magnetic field (one cannot use electric fields since the anti-atom is neutral) and interrogate them with lasers.

一个做这的方法就是在一个不均匀的磁场(由于反原子是中性的不能够使用电场)中限制反原子并且用激光识别它们。

It will use magnetic fields to confine hydrogen isotopes and heat them to hundreds of millions of degrees Celcius.

它利用磁场约束氢的同位素并将其加热到数亿摄氏度。

The magnetic traps employed to hold the antihydrogen are only strong enough to confine it if it is colder than around half a degree above absolute zero.
