摘要：

We report a study of fluctuation effects in the resistance, R, and the thermoelectric power, S, of melt-processed BiSrCaCuO (2212) and sintered BiPbSrCaCuO (2223) polycrystalline materials. Applying several theoretical models to the analysis of experimental results we extract a number of physical parameters for these systems: the Fermi energy, interlayer coupling strength and atomic Debye temperatures for Bi and Pb. The results are in good agreement with data obtained in other studies of similar materials.
