以下为句子列表：
英文: Once an antiproton and positron have joined forces, the resulting antihydrogen atom is electrically neutral and thus no longer caged by the electrical fields in the trap. The atom drifts to where it wants to go,said Dr.
中文: 从那里反质子进入一个“捕获线圈,”在一个磁场中它们中的大多数以能量被吸收而且以电子涡流辐射掉了,降低它们的温度为绝对零度上大约15度且速度为每秒数百英尺。

英文: Scientists in 1995 succeeded in producing anti-atoms of hydrogen, and also anti-deuteron nuclei, made out of an antiproton and an antineutron, but not yet more complex antimatter.
中文: 科学家在1995年成功生产了氢的反原子,以及反氘核核子,由一个反质子和一个反中子生成,仅仅还不能是更为复杂的反物质。

英文: To do that, CERN built the Antiproton Decelerator, which uses electric and magnetic fields to slow the particles from near light speed to about one-tenth of that, he said.
中文: 为了要做那些,CERN建造了反质子加速器,他说，使用电场和磁场把接近光速度的粒子减慢到光速的十分之一左右。
