摘要：
Using the power-law analysis of current-voltage characteristics, the new data have been obtained corroborating the realization in granular high-T-c samples the two-dimensional behavior with an anomalously large difference between mean-field critical temperature and the temperature of Berezinsky-Kosterlitz-Thouless transition. It is shown that such a behavior is due to a small effective thickness of superconducting layers and their non-perfect attachment in the HTS intergranular boundaries of metal oxides.
