摘要：

The melting point of high T(c) superconductors was determined as a function of oxygen partial pressure. It decreased with the decrease in oxygen partial pressure. It was concluded that the melting is a kind of reduction reaction, in the form of Solid (I) --> Solid(II) + liquid O2. The enthalpy change DELTA-H0 and the entropy change DELTA-S0 for the reaction are calculated from the oxygen partial pressure independence of melting point.
