【Abstract】 The critical state equation for an infinite superconductor slab was resolved by self-consistent method , while the self-field effect of critical current was taken into account. Functional expression for average critical current density of the slab was gained. The dependence of self-field effect on magnetic field and sample dimension was analysed. Dimension effect of average critical current density was also discussed.更多还原
