Abstract :
The major normal and superconducting parameters of several cuprate superconductors are evaluated and discussed. The effects of the two-gap structure in Y1Ba2Cu3O7 are especially emphasized. It is pointed out that, for the two-gap superconductor such as Y-Ba-Cu-O, the analysis of the strength of the coupling should be carried out with considerable care. This is connected with the presence of three coupling constants, whose values can be entirely different
