摘要：
The repulsive energies between ions in YBa2Cu3Ox were calculated using Wedepohl's free ion model. They were tested by using them to study cohesive energies and lattice constants of Y2O3, BaO and CuO. We have discussed the effects of repulsive interactions on bond-natures in YBa2Cu3Ox by considering similarities of bonds in these oxides to YBa2Cu3Ox and elastic constants. This compound is likely to contain some covalent contributions due to Cu-O bondings. © 1990.
