The second epiphany was that the extracted gas had a significantly different isotopic makeup from what is usually produced in nuclear reactors. 第二項大發現是，萃取出來的氣體，同位素組成與一般核反應器中所產生的大不相同。
The Anqing copper deposit has a complicated sulfur isotope composition ,which can not be explained by the variations of a single sulfur source or the physico-chemical conditions. 安徽安慶銅礦床的硫同位素組成複雜，不能用單一硫源或物理化學條件的變化來解釋。
