A brief overview of recent superconductivity research at NIST is presented. Emphasis is placed on the new high-temperature oxide superconductors, though mention is made of important work on low-temperature superconductors, and a few historical notes are included. NIST research covers a wide range of interests. For the new high-temperature superconductors, research activities include determination of physical properties such as elastic constants and electronic structure, development of new techniques such as magnetic-field modulated microwave-absorption and determination of phase diagrams and crystal structure. For the low-temperature superconductors, research spans studying the effect of stress on current density to the fabrication of a new Josephson junction voltage standard.
本文简要概述了美国国家标准与技术研究院（NIST）近期的超导研究。重点介绍了新型高温氧化物超导体，不过也提及了低温超导体方面的重要工作，并包含了一些历史记录。NIST的研究涵盖了广泛的领域。对于新型高温超导体，研究活动包括确定诸如弹性常数和电子结构等物理性质、开发诸如磁场调制微波吸收等新技术以及确定相图和晶体结构。对于低温超导体，研究范围从研究应力对电流密度的影响到制造新的约瑟夫森结电压标准。
