摘要：

The normal and superconducting characteristics of planar junctions made on 90K and 60K YBCO phases have been analyzed whitin the framework of a phenomenological model based on a density of states expressed as a superposition of a linear contribution and a traditional BCS one. A satisfactory qualitative agreement with the experiments has been obtained.
