自1987年在提高超导材料的超导临界温度方面取得突破后,世界上迅速掀起了一股超导热。之后,超导临界温度不断被提高,目前已达到153K,即摄氏零下120度。但随着实际应用上碰到的一些工程上的难关,使得超导技术的工程应用进展缓慢,超导热一度开始慢慢降温。 美国阿贡国家实验室在高温超导材料研究和应用领域一直领先,阿贡在开展这方面研究的过程当中,一直与工业企业界密切合作,将研究、开发和应用结合在一起。目前,终于在高温超导材料的应用方面取得了新进展,设计出“飞轮系统”。 除阿贡外,美国其他一些研究人员也在高温超导应用方面取得了瞩目的成果。专家认为,从目前的情形看,高温超导材料的实际应用比原来任何人所预计的都要快。
Since the 1987 breakthrough in improving the superconducting critical temperature of superconducting materials, the world has rapidly launched a superconductivity. Afterwards, the superconducting critical temperature has been continuously increased and it has reached 153K, which is minus 120 degrees Celsius. However, with some engineering difficulties encountered in practical applications, the application of superconducting technology has progressed slowly, and superconducting heat has slowly cooled down. Argonne National Laboratory has been leading the research and application field of high-temperature superconducting materials. In the process of carrying out this research, Argung has been working closely with the industrial community to combine research, development and application. At present, new progress has been made in the application of high-temperature superconducting materials and a “flywheel system” has been designed. In addition to Agung, other U.S. researchers have also achieved remarkable results in HTS applications. Experts believe that from the current situation, the practical application of HTS materials is faster than anybody expected.
