铀后的

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？

In the Purex process, the separation of plutonium from uranium is achieved by using reductants which can quickly and quantitatively reduce Pu to Pu.Up to now the reductant U-N2H4 is still used widely for separation of Pu from U in the rep...

目前动力堆乏燃料后处理中广泛采用的钚还原剂还是由肼支持的四价铀，而醛、肼、羟胺类有机无盐还原剂在Purex流程中的应用目前还停留在实验室研究阶段。
