摘要：
The complex AC susceptibility [chi(T,b(o),B)] for two cylindrical YBa2Cu3O7-x samples has been measured. The critical current densities for the inter- and intragranular components are extracted from these results and the volume fractions of the components are calculated using various models. The solvent used during milling of the starting powders seems to have a marked effect on both of these parameters.
