The discovery of YBa₂Cu₃O₇₋δ (Y123 or YBCO) in 1987 emerged as a landmark in superconductivity research---it was the first high-temperature superconductor (HTS) with a critical transition temperature (Tc) surpassing the boiling point of liquid nitrogen (77 K).
1987 年发现的钇钡铜氧（YBa₂Cu₃O₇₋δ，简称 Y123 或 YBCO）是超导研究史上的一座里程碑 ------ 它是首个临界转变温度（T_c）突破液氮沸点（77K）的高温超导体（HTS）。
This breakthrough revitalized the field, focusing efforts on the REBa₂Cu₃O₇₋δ (RE123 or REBCO, RE = Y, Gd, Sm, Nd ...) family.
这一重大突破彻底激活了超导领域的研究活力，全球研究重心随即转向稀土钡铜氧（REBa₂Cu₃O₇₋δ，简称 RE123 或 REBCO，其中稀土元素 RE 包括钇、钆、钐、钕等）系列超导体。
