一系列的超低温实验安河内先生自1959年12月以来,一直是东京大学物理系、日本大学理工系物性实验的教授。1960年,安河内先生的实验室装备了氦液化器之后,就开始进行极低温实验。当时,第二类超导体的物理结构,不仅在理论上已得到确立,而且强磁场超导体也逐步地被人们所发现。安河内先生很快就看出了超导技术在工业应用的重要性,并开始了该项目的调研工作。对于该项目的研究,安河内先生提出了“广而深”的研究方案。有人却提出了“狭而 A series of ultra-low temperature experiments Mr. Ann Hana has been a professor of physics experiments at the University of Tokyo and Department of Physics and Engineering, University of Tokyo since December 1959. In 1960, Mr. Ann Hanoi’s laboratory equipped with a helium liquefier, began cryogenic experiments. At that time, the second type of superconductor physical structure, not only in theory has been established, and the strong magnetic field superconductor also gradually been found. Mr. Ann Hanoi soon saw the importance of superconducting technology in industrial applications and started the research work on the project. For the study of this project, Mr. An Hanoi proposed a “broad and deep” research program. Some people have proposed "narrow
