为了降低Bi2223/Ag高温超导带材的交流损耗，科研人员在该种带材中加入了阻挡层。1997年，瑞士日内瓦大学凝聚态物理系应用物理组的R. Flukiger教授等人首先提出，随后迅速为人们所接受，成为能降低超导体交流损耗的一种有效的方法。到目前为止，人们在阻挡层材料的选择、材料 In order to reduce the exchange loss of Bi2223 / Ag high temperature superconducting tapes, researchers have added barriers to the tapes. In 1997, Prof. R. Flukiger, applied physics group of the Department of Condensed Matter Physics, University of Geneva, Switzerland, first proposed that it was rapidly accepted by the people and became an effective method to reduce AC loss of superconductors. So far, people have chosen barrier materials, materials
