贫金属星三种典型重元素丰度的分量比例

Component proportions of the abundances of three typical heavy elements in metal-poor stars

利用太阳系的重核素丰度,结合贫金属星重元素丰度的观测值及星系化学演化的计算结果,计算了不同金属丰度恒星三种典型重元素丰度的s-过程、r-过程贡献的相对比例。

Based on the solar system heavy nuclicle abudances ,with the observed abundances of heavy elements in metal-poor stars and the conclusions of the galactic chemical evolution,the relative contribution proportions of the s-process and the r-process abundances of three heavy elements in metal-poor stars with various metallicity are determined.
