【Abstract】 A critical state model calculation was proposed for the dependence of the transport critical current density on the applied magnetic field and the thickness of a slab shape type Ⅱ superconducting sample. The coexistence of Meissner state range with vortex state range in a sample was considered in this model calculation. The calculation result was discussed and compared with experimental measured transport critical current density of Tl 2Ba 2Ca 2Cu 3O 10 samples.更多还原
