magnetic bottle [等离子] 磁瓶 ; 核聚变实验中用的约束等离子体的磁场 ; 是一种磁笼 ; 磁捕集器
All this happened inside a magnetic bottle that traps the antihydrogen atoms.
这一切都发生在一个俘获反氢原子的磁瓶里。
We build a strong 'magnetic bottle' around where we producethe antihydrogen and, if they're not moving too quickly, they aretrapped, " he told BBC News.
我们创造出一个强大的‘磁瓶’，并在其周围产生反氢原子，如果它们的移动速度不是很快，便会被捕获。
As the height of the magnetic barrier is slowly lowered, the fastest atoms leave the bottle and the remaining gas rethermalizes via elastic atomic collisions at lower and lower temperatures.
由于磁化空腔的效能慢慢降低，那么那些速度还很快的原子就很容易逸出，而其余的气体粒子在不断的碰撞中消耗能量，使得温度降低。
