340 m铋系高温超导导线近日在清华大学应用超导研究中心研制成功。这是我国目前高温超导长导线的最新记录,标志着我国已掌握了处于世界先进水平的超导线材产业化技术。 高温超导材料一般是指在液氮温度(零下196℃)电阻可接近零的超导材料。同样直径的高温超导材料和普通
340 m bismuth-based high-temperature superconducting wire recently developed at Tsinghua University Applied Superconductivity Research Center. This is the latest record of the current high-temperature superconducting long wire in our country, which indicates that our country has mastered the superconducting wire industrialization technology in the world’s advanced level. High temperature superconducting materials generally refers to superconducting materials with near-zero electrical resistance at liquid nitrogen temperatures (minus 196 ° C). The same diameter of high temperature superconducting materials and ordinary
