One of the big detectors which record these collisions, they didn't think there was technology that could withstand the radiation that would be created in the LHC, so there was basically a lump of lead in the middle of this object with some detectors around the outside, but subsequently we have developed technology.
在打造能记录这些碰撞的 大型探测器其中之一时， 他们并不认为科技能够先进到 让它承受大型强子对撞机 可能产生的辐射， 因此在这些探测器中间 有一块铅块， 不过随后我们发展了科技。
