1.Before broaching the subject of this lecture, I should like to recall that the discoveries of radium and of polonium were made by Pierre Curie in collaboration with me.

在开始讨论这次讲的话题之前，我还想回忆一下，镭和钋发现是皮埃尔·居里与我合作完成的。

2.We found that pitchblende contains at least two radioactive materials, one of which, accompanying bismuth, has been given the name polonium, while the other, paired with barium, has been called radium.
