据今年国家科委召开的超导技术战略目标汇报会的报道,我国的高温超导研究领先世界,高温超导技术发展迅速,在材料、器件、基础研究方面均有突出的成绩。我国制造的临界温度达132K的新型超导材料,至今保持着世界最高纪录。我国用熔融结构法制备的钇钡铜氧体材料,在77K和1万高斯磁场下,临界电流密度接近7万安培/平方厘米,为现今国际上最好水平。
According to the report of the strategic target reporting conference of superconducting technology held by the State Science and Technology Commission this year, the research on HTS in our country is a world-leading one and HTS technology has been developing rapidly with outstanding achievements in materials, devices and basic research. China’s new critical temperature of 132K superconducting materials, has maintained the highest record in the world. China yttrium barium copper oxide material prepared by the melt structure method, at 77K and 1 million Gauss magnetic field, the critical current density close to 70,000 amps / square centimeter, is now the best in the world.
