同位素丰度 [核] isotope abundance
[核] isotopic abundance
- 通过实验,建立了MC-ICPMS的同位素丰度绝对测量方法。
By correction of isotopic standards, the absolute measurement method of MC-ICPMS was established. - 分析包括钾-氩测年,稳定同位素丰度分析,放射性碳测年,以及其他放射性分析。
Analytical services include potassium-argon age determinations, stable isotope ratio analyses, radiocarbon age determinations as well as other radiometric analyses. - 由于金属氢化物体系一般具有氢同位素效应,使得交换平衡时气-固相间的同位素丰度发生变化。
Because of the hydrogen isotope effects in metal hydride-hydrogen system, abundances of hydrogen isotopes are different between solid and gas phase under exchange equilibrium.
