n.防原子

The antiatom researchers will have to wait until May 2006 before they can resume their battle to beat hydrogen's evil twin into submission. 反原子的研究人員，得等到2006年5月，才能重啟戰(zhàn)局，設法制服氫原子的邪惡孿生兄弟。

These neutral antiatoms pass effortlessly through a high-potential barrier that blocks all stray antiprotons that are not part of an antiatom. 這些中性的反原子，毫不費力便穿過那可以擋住反質子（還沒形成反原子）的高位能障礙。
