【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 coefficiewt C 2 is below zero in some sample,we sugget some possible reasons to explain this phenomenon.更多还原
