摘　　要：利用银河系三成份先厚后薄星系化学演化模型,对4种Fe峰元素(Ti,V,Cr,Mn)的化学演化进行了计算,得到这些元素的丰度分布随金属丰度的变化规律,同时将计算曲线与丰度观测结果进行了比较,并对Fe峰元素合成场所进行了讨论.On the bases of the galaxy evolution theory, the therotical chemical evolution pre-thin modle of there zones is used to calculate the Galactic chemical evolution of four kind re-peak elements （Ti,V,Cr, Mn）in the solar neighborhood, gaining the rule of these elements distribution with [Fe/H]. Then, spectroscopic abundances determined dwarf and Giant star of different metallicities are compared. In the end, nucleosynthesis sites of the re-peak elements are discussed.
