【Abstract】 The principles of the single turn inductive method were described in this paper. Incorporated with the new electronic and computer technique, an improved apparatus was set up to measure the critical current of Bi-2212 rings. Results show that the smaller electric fields criterion used, the smaller measurement error got.更多还原
