| 英文摘要 | We apply the parametric model to fit the surface abundances of three lead-rich stars (HD187861, HD196944 and HD224959) without adopting any specific stellar model. It shows that the calculated result can fit the observed data well whether the reaction branchings are taken into account or not. Besides, by the comparison of the model parameters of the three lead-rich stars with, those of two very metal-poor stars (LP625-44 and LP706-7), we find out that the average neutron exposure of the former is larger than that of the latter, but the dredge-up extent is smaller. We come to the conclusion that the parametric model is significant of constraints on the stellar model, though it is very simple. |
