提高英语听力能力 找对方法很重要!
Marie continued to work at P’ operators. Untile one day while testing substance called pitch blende, she got the result that sent the electrocmeter off the scale. This is the highest reading anyone has seen and since it was so much stronger than uranium, it must be coming from an entriely new element. The question was what was it?
Since pitch blende was a mixture of different blende elements jumbled together, some how she had to free her new element from compound material.
In Marie Curie’s notebooks, it’s mean, she talks about studying with hundred grams material, were losing bits all over the plate, you know, really substential amount of rock, this really hardcore physical labour, you’ve just got to pound and grind, untile you got a nice, fine, free flow material at that point, you can move really from the engineering into chemistry, the next step is going to be actually trying to dissolve it up, and she would had chosen nitrous acid because what we would had known was this could dissolve up
