ANALYSIS OF THE HIGH Tc OXIDE SUPERCONDUCTORS FROM THE GOLDEN COORDINATES
对高温氧化物超导体的黄金坐标分析

In this paper, more than sixty high-Tc oxide superconductors are analysed again with Vil-lars coordinates. Moreover, we introduce two new coordinates, namely, the average electrone-gativity and chemical combination valence. It is found that the high-Tc oxide superconductors are distributed more concentratively in the diagram of these new coordinates.
