Percolation theory is used for a comparative analysis of curves of the superconducting transition in ceramic YBa2Cu3O7 - in a zero magnetic field found through measurements of the resistance, R(T), and the dynamic susceptibility, (T). When there is an oxygen deficiency (> 0), the grains have a wide distribution with respect to the superconducting transition temperature Tc.
