krypton isotope

基本解釋

The krypton and xenon isotope ratios in the gas samples provided a surprising result: They did not match the ratios found in the primordial cloud that spawned the solar system.
氣體采樣中的氪和氙同位素比值產生了一個令人吃驚的結果：這些比值跟在形成太陽系的原始云團中所發(fā)現的比值不一致。
In particular, the researchers were studying the isotope ratios--or the comparative abundances of the different forms of a particular element--of the gaseous elements krypton and xenon.
特別值得一提的是，研究人員研究了氪和氙兩種氣體元素的同位素比值。同位素比值是指一種特定元素中各種同位素之間的豐度之比。
