摘要: 研究双漏斗肥皂膜实验中肥皂膜的形状、特性以及它随两漏斗距离的变化过程.从理论上导出并经实验验证一个重要结论:两漏斗口的最大距离等于其半径的1.325倍,然而这一点常常被忽视.

关键词: 肥皂膜实验, 形状, 双漏斗, 悬链线, 变分法

Abstract: The shape of soapfilm and its characteristic and process of variation in the experiment on double funnel soapfilm are researched. An important conclusion is educed in theory and validated by experiment: the maximum distance between the two funnel is the funnel radius times 1. 325. The carelessness about this problem in some textbooks is pointed out.

Key words: experiment on soapfilm, shape, double funnel, catenary, variation calculus
