我們常可以在自然界中發現漩渦的存在,但其存在的形體與性質也不盡相同,為了研究漩渦的結構與形體,筆者分析出多種會對漩渦產生影響的因素:開始放流的水而高度、放流洞口大小、有無破壞漩渦結構的阻礙、單孔落流漩渦與雙孔落流漩渦、還有流體的黏滯度對漩渦的影響, 但漩渦是一個不斷改變的流體,非常難以觀察,且自然界的漩渦也不是說出現就出現,所以必須設計一個簡易實驗器材來觀察,並用數位攝影機紀錄下來,再慢慢分析,而我們也可以在這個實驗中了解漩渦的結構,和體會到漩渦所表現出自然界的力與美的一面。‧We can always find in nature of different swirl’s forms and properties. To study the swirls, we analyzed such factors, as the beginning water level, the size of the hole, the presence of obstruction that will destroy the structure of swirls, differences between single-hole-swirls and twin-hole-swirls, and the viscosity of fluid. Because swirls change all the time, it is very difficult to observe. We designed a device .The procedure was recorded with a digital video camera and analyzed it. The study helps us understand the structure of swirls and admire the beauty of swirls.
