摘要：

Electron tunneling experiments in very well-characterized polycrystalline samples of Ba1-xKxBiO3 and Bi2Sr2Ca2Cu3O10-delta show very clear features of the energy gap. The energy gap 2DELTA and the ratio 2DELTA/K(B)T(c) were determined. In the Ba1-xKxBiO3 compound we also study the behavior of the tunneling conductance in the normal state.
