论文部分内容阅读
在我的实验室笔记本上,1960年5月2日记载着:“4月22日,星期五,我进行了下述实验,其目的在于测量一种超导体的能隙。”这显然是一件不平常的事情,不但因为我难得在我的笔记本上做笔记,并且因为这次实验的成功是我今天荣幸而高兴地得以向你们演讲的原由所在。在这篇演讲中我想尽力回忆起一些导致记载这本笔记本的活动和思想,尽管这些现在对我来说似乎是偶然的事情要描述起来是很困难的。我希望我这个主观的回忆比起一篇严格的技术讲演来会使你们更感兴趣,特别是因为现在已经有许多评论超导隧道的好文章问世了。
On my lab notebook, May 2, 1960, reads: “On Friday, April 22, I conducted the following experiment, which was designed to measure the energy gap of a superconductor.” This is obviously not the case at all It’s not just because I rarely take notes in my notebook, and because the success of this experiment is why I am honored and happy to address you today. In this talk I tried my best to recall some of the activities and thoughts that led to the recording of this notebook, though these now seem to be occasional things to me to be very difficult to describe. I hope my subjective memories will be of more interest to you than a strict technical talk, especially since there are now many good articles on superconducting tunnels.
