摘要
利用太阳系的重核素丰度以及s-过程、r-过程的相对贡献,结合贫金属星重元素的观测值及星系化学演化的计算结果,计算了不同金属度贫金属星重核素丰度分布。
Based on the heavy-nucldie abundances of the solar system and the relative contribution ratios of the s-process and r-process to the abundances, combined the observations of the heavy elemental abundances of the metal-poor stars with the calculating results of the Galactic chemical evolution, the heavy-nuclide abundance distributions of the metal-poor stars in different metallicities are calculated
