The condensation energy density of Bi-2223 superconductor, which determined the property of the critical current, was measured and the possibility of superconductor was discussed. It was found that Bi-2223 superconductor had potential equal to the practical rare earth-123 superconductor at low temperatures. In addition, the superconducting magnet working at liquid nitrogen was fabricated and magnetic field of 1.3T was successfully generated.

测量了决定临界电流特性的Bi-2223超导体的凝聚能密度，并讨论了超导体的可能性。研究发现，Bi-2223超导体在低温下具有与实用的稀土123超导体相当的潜力。此外，还制作出了液氮下工作的超导磁体，并成功产生了1.3T的磁场。
