Studies on the Component CoefficientC2 of the Weak s-process
摘要/Abstract
摘要：
利用贫金属星中子俘获元素丰度的模型计算了30颗样品星的分量系数,并详细分析了弱s过程分量系数C2小于零的各种可能原因
Abstract：
Using the model of determining the relative contributions from different nucleosynthesis processes to the abundances of the heavy elements in metal-poor stars,we calculate the component coefficients of 30 sample stars.The results show that the weak s-process component coefficiewtC2 is below zero in some sample,we sugget some possible reasons to explain this phenomenon.
