牛津大学克拉伦登实验室的氦液化车间
牛津大学克拉伦登实验室的氦液化车间 牛津大学克拉伦登实验室的氦液化车间 弗雷德里克·林德曼，托马斯·基利 编者按 在20世纪30年代早期，液氦对于研究很低温度下物质性质的物理学家来说是十分珍贵的。在本文中，牛津大学的物理学家弗雷德里克·林德曼及其同事宣布研发出了一种能生产大量液氦的新方法。他们采用突然改变液态氢压力的方式来冷却氦，可以用这种较便宜的... -

液氦的λ现象和玻色-爱因斯坦简并
液氦的λ现象和玻色-爱因斯坦简并 液氦的λ现象和玻色-爱因斯坦简并 伦敦 编者按 1938年初，《自然》刊载了两篇有关液氦超流动性的最早报告，那是俄国的彼得·卡皮查和剑桥的约翰·艾伦与冬·麦色纳各自独立发现的。两篇文章都提到当温度低于2.17 K时液氦的黏度似乎减小至零。有人认为这是由于氦原子排列成为类似金刚石晶体那样的有序结构。而这篇文章中弗里茨...
