antiatom

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. 反原子的研究人员，得等到2006年5月，才能重启战局，设法制服氢原子的邪恶孪生兄弟。

These neutral antiatoms pass effortlessly through a high-potential barrier that blocks all stray antiprotons that are not part of an antiatom. 这些中性的反原子，毫不费力便穿过那可以挡住反质子（还没形成反原子）的高位能障碍。
