Flux conservation equations of high-T-c superconductors with different shapes and their application in electromagnetic measurements

In consideration of the importance of the specimen shape effects and field orientations in electromagnetic measurements, we extended the conservation equations of one-dimensional (1D) specimens to two-dimensional (2D) ones in parallel fields, the corresponding parameters were calculated and tabulate d. Then we discussed the problem of 2D specimen in a perpendicular field. B ased on the derivation of general flux conservation equations, we presented their simple applications in measurements by providing the commonly used m easurement equations in typical measurement methods.
