恒星重元素丰度随金属丰度的变化规律

The Variation of the Heavy element Abundances in Metal poor Stars with the Metallicity

利用太阳系的重核素丰度，以及贫金属星的ｓ过程和ｒ过程对丰度的相对贡献，结合贫金属星重元素丰度，提出了一种计算不同金属度贫金属星重核素丰度的方法，并用镁的丰度观测值检验了我们的计算结果．

Based on the heavy nuclide abundances of the solar system and the relative contributions of the s process and r process to abundances,combined the observations of the heavy elments abundances of the metal poor stars and the observed data of Mg, the method to calculate the the heavy nuclide abundaces of the metal poor stars is examined.
