九年义务教育初中物理课本在密度章节中,沪科版和人教版都提到瑞利通过测密度的方法发现了氩气,而获得诺贝尔物理奖。许多物理学史的书对此很少有反映。本文就氩元素的发现过程作些介绍,供老师们参考。 Nine-year compulsory education junior high school physics textbook In the density section, both the Shanghai edition and the People’s Education Edition mentioned that Rayleigh discovered argon by measuring density, and won the Nobel Prize in physics. Many books in the history of physics rarely reflect this. In this article, we will introduce the discovery process of Argon for teachers’ reference.
