“同位素丰度”的概念、定义、翻译、参考文献-科学参考

单词	同位素丰度
释义	同位素丰度 Encyclopedia 理学元素符号释 isotopic abundance同位素丰度以原子百分数表示的地壳中某种元素各同位素的相对含量。例如，氧的同位素16O、17O、18O的原子百分数即同位素丰度（%）为99.76、0.04和0.20。自然界中氟、钠、铝等21种元素都只有一个同位素，因此19F、23Na、27Al等的同位素丰度为100%。 Physics 原子核物理学、粒子物理学原子核物理学 isotopic abundance同位素丰度＞原子核物理学＞原子核基本性质＞释义 isotopic abundance同位素丰度 isotopic abundance同位素丰度^† Astronomy isotopic abundance同位素丰度
