摘要：

Precision measurements of critical current densities at zero applied magnetic field J(c) for six granular Y1Ba2Cu3O7-delta Samples have been performed by using a low frequency induction method. Also, the intergrain resistivity rho(ct) for each sample has been extracted from the normal-state resistivity. It is found experimentally that at any temperature distance from the transition, J(c) is inversely proportional to rho(ct). A way to estimate J(c) from the resistivity of the granular samples in the normal state is thus open.
