| 英文摘要 | We present here some observed data on 11 mildly metal-poor stars with -1.3 less than or equal to [Fe/H] less than or equal to -0.6. The model parameters and the abundances of 14 elements are determined. We also discuss the relation between the abundance ratio and the metallicity. The or elements (Mg, Si, Ca, Ti) are overabundant relative to Fe with a varying scatter at each given metallicity. Most of the iron-peak elements (V, Cr, Ni, Cu) are also overabundant relative to Fe by amounts that are independent of [Fe/H], while [Mn/Fe] increases with increasing metallicity. [Na/Al] is overabundant in the sample with [Fe/H]> -1.1 and definitely overdeficient in the sample with [Fe/H]< -1.1. |
