Abstract
Ideal (x = 7) and close to real (x = 6.85) composition of the YBa2Cu3O x superconductor can be assumed to change on the boundary with negativ e charge surface. The two used methods of calculation (generalized mea surements and absorption) show a considerable reduction of copper ion valence.
