研究了35颗贫金属恒星的局部热力学平衡（LTE）锌丰度（Zn）在3.0 ~ 0.5范围内的分布。用正常SNe II、HNe和Ia模型构建的化学演化模型更好地解释了这一趋势，该模型考虑了SNe Ia模型的金属丰度效应和单简并情景。
The local thermodynamic equilibrium (LTE) abundances of zinc (Zn) of our sample of 35 metal-poor stars were explored in the range of � 3.0 � 0.5. This trend is better explained by a chemical evolution model constructed with models of normal SNe II, HNe, and SNe Ia, in which the metallicity effect and the single-degenerate scenario of the SNe Ia model are incorporated.
