krypton isotope

基本解释

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.
气体采样中的氪和氙同位素比值产生了一个令人吃惊的结果：这些比值跟在形成太阳系的原始云团中所发现的比值不一致。
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.
特别值得一提的是，研究人员研究了氪和氙两种气体元素的同位素比值。同位素比值是指一种特定元素中各种同位素之间的丰度之比。
