In this paper, formulas for relationship among oxygen mass spectra peak heights and for calculating oxygen isotopeabundance are drived.
本文推导出氧质谱峰高之间的关系和计算氧同位素丰度的公式。

This approach underpins much of my research on energy and nutrient flux, and has involved both natural abundance and enriched isotope tracing techniques.
该方法巩固了对于我在能量和营养流的研究，并结合了自然丰度和浓缩同位素跟踪技法。

For the other two methods, the ion extraction characteristics were computed for various conditions such as applied voltage, initial atom density and abundance of the aimed isotope.
