n. 同位素丰度测量；同位素丰度测定
双语例句
- Absolute isotopic abundance measurement
绝对同位素丰度测量 - The study shows that the analysis precision of the isotopic abundance and the age will rise as the spectral measurement precision increases, and that if the spectral measurement precision is not enough, the analyzed results by the PC/ FRAM software might be lower.
研究结果表明，同位素丰度和年龄的分析精度随能谱测量精度的提高而提高，如果能谱的测量精度不够，通过PC/FRAM分析得出的钚材料的同位素丰度和年龄有偏低的可能。
