In the superconducting studies of high Tc copper oxides, the element substitutions is a ettective way to discovery new superconductors which is also a important method that the element properties can produce the influence of the crystal structures, electronic structures, normal state features and superconducting state characteristics, even those are the information source of the exploration superconductivity mechanism, The Zn substitution effects are important study theme for the rich and distinctive contents. In this paper, the superconductivity mechanism of copper oxides are used to study the nature of Zn element substitution and the conclusion is that the effect of Zn element substitutions is determined by the superconducting mechanism. Key words： High Tc copper oxides;High Tc superconductivity mechanism;Effect of Zn substitution.
