前言多股细芯经扭转后的超导材料,其主要优越性是在随时间而变化的磁场中,稳定性高并且损耗低。因而,用A—15型超导化合物Nb_3Sn(或V_3Ga,V_3Si)生产多股细芯超
Foreword Multi-core finely-twisted superconducting materials have the main advantages of high stability and low loss in a magnetic field that varies with time. Thus, the use of A-15 superconducting compounds Nb_3Sn (or V_3Ga, V_3Si) production of multi-strand fine core super
