  • Online:2009-08-20 Published:2009-08-20

摘要: 气体液化的发展经历了一个曲折而漫长的过程,刚过去的2008年是氦气液化100周年.通过回顾气体液化的历程,说明人类认识知识是个循序渐进的辩证过程,同时也纪念为此做出杰出贡献的杜瓦、昂内斯等科学家.

关键词: 气体液化, 辩证过程, 温度测定, 空气分离

Abstract: The development of liquefaction has experienced a long and tortuous process. Helium was liquefied 100 years ago, so 2008 was a historical year. By looking back the history of liquefaction, we may know the cognition of knowledge is a dialectical process. This article is for commemorating the brilliant scientists Sir James Dewar and Kamerlingh Onnes for their outstanding contribution in the liquefaction

Key words: liquefaction, dialectic process, temperature measurement, air separation
