摘要：

It is shown that T-c is closely related to oxygen nonstoichiometry for various kinds of high-T-c superconductors. The separate determination of valences of multi-valent ions has revealed that positive holes are not always located on the CuO2 planes. The oxygen nonstoichiometry was determined as functions of oxygen partial pressure and temperature.
