英文摘要：

The purpose of this paper is to study the additive effects on the superconductivity and structure of high-temperature oxide YBCO superconductors. According to existing experiments of the doping YBCO, the changes of superconductivity and structure of YBCO which was doped with typical elements at its various locations was stud- ied, and the important effects of doping on YBCO was analyzed. The research of additive effect can improve the applied properties of YBCO and supply more informations for exploring mechanism of superconduetors.
