最近几十年来,物理学家对低温发生了愈来愈大的兴趣。物质的磁性、半导体、金属和核现象等的研究者都开始在这方面进行他们的工作。在所有最大的科学研究中心都建立了获得低温的装置。这些装置的功率和数目一年比一年飞快增长。到底是什么使大家对低温发生这么大的兴趣呢?
In recent decades, physicists have become increasingly interested in cold temperatures. Researchers of the magnetic, semi-conductor, metal, and nuclear phenomena of materials have begun to carry out their work in this area. At all of the largest scientific research centers have established devices to obtain low temperatures. The power and number of these devices have grown rapidly year after year. What makes everyone interested in cold temperatures?
