摘要: 利用旋转椭球模型和最小势能原理,研究桌面上水银液滴呈现球形的条件,结论是其半径小于毛细常数的五分之一.

关键词: 水银液滴, 表面张力, 形状, 最小势能原理

Abstract: The condition of a mercury drop showing sphericity on a desktop is studied by using the model of spberoid and principle of minimum potential energy. It concludes that its radius is less than one fifth of its capillaryconstant.

Key words: mercury drop, surface tension, shape, principle of minimum potential energy
