1986年高温超导材料的发现为超导技术研究翻开了崭新的一页，10多年的研究也确实取得了很大的进展．但是由于在材料物理特性、制备工艺，特别是成材技术上的困难，本世纪应用于强电强磁场工程领域，从而替代传统低温超导材料的可能性不大．世界各国在低温超导材料及其应用上的
The discovery of high-temperature superconducting materials in 1986 has opened a completely new chapter in the research of superconductivity and great progress has been made in more than 10 years of research. However, due to the physical properties of the material, the preparation process, especially the technical difficulties of the finished product, it is unlikely that this century will be applied to the fields of strong electric and magnetic fields so as to replace the traditional low-temperature superconducting materials. Countries in the world in low temperature superconducting materials and their applications
