pitchblende
解釋
瀝青鈾礦-
But an unexpected fact was noted : certain minerals ( pitchblende, chalcolite, autunite ) had a greater activity than might be expected on the basis of their uranium or thorium content
但是一個意外的事實引起了我的注意：某些礦物質（瀝青鈾礦物質、銅鈾雲母或鈣鈾雲母）的活性比根據其鈾或針含量所判斷的要高。 -
Pitchblende and chalcolite are much more radioactive than uranium itself.
瀝清鈾礦和銅鈾雲母比純鈾的放射性強得多。 -
In reality the proportion of the hypothetical element was far lower and it took several years to show unequivocally that pitchblende contains at least one highly - radioactive material which is a new element in the sense that chemistry attaches to the term
實際上這種假設中的元素的濃度要小得多，我們花了幾年時間才明確無誤地證明瀝青鈾礦物質中至少含有一種高放射性物質，在化學意義上這就是一種新元素。 -
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
我們發現瀝青鈾礦物中至少含有兩種放射性物質：與鉍伴生的命名為釙，與鋇伴生的命名為鐳。
