of or relating to or having the relation of an isotope
双语例句
用作形容词 (adj.)
How could such a change in isotopic composition have come about? 同位素的组成有这样的变化,究竟是如何发生的?
Conversely,the isotopic characteristics will be well explained by assuming that the UHPM occurred in the crust instead in the upper mantle. 相反,如果认为大别山超高压变质岩就在地壳内形成,则大别山超高压变质岩同位素的所有特征就很好解释了。
