铀矿

Marie:When the uranium and thorium are in the pitchblende,the reading is eight, but individually they only total four. Why,then, do they give out twice as much when they're in the pitchblende as they do when they're tested separately?

玛丽：当铀和钍包含在铀矿里的时候，读数是八，而分别测量后加起来只有四，那麼为什麼存在於铀矿中所产生的能量竟是单独产生能量之和的两倍？
