摘要
　　本研究主要利用高速攝影機拍攝落下液滴與平板表面靜止液滴間撞擊的過程，改變的條件主要為落下液滴的高度及撞擊相對位置，本實驗採用的方式是利用鏡子反射光源及影像，同時將兩方向影像錄製在同一畫面中，方便對照比較。實驗的結果發現：(1)撞擊是否產生飛濺，仍可用Mundo(1995)的判別式判別，(2)撞擊情況會產生一牛角狀外形，角度的大小與下降幅度與撞擊相對位置有關聯性，(3)比較撞擊位置與飛濺型態時，發現不同的撞擊能量在不同的撞擊位置時，其產生的飛濺型態也會有所不同。

Abstract

　　This research used high speed camera to take pictures of the impact process between a falling droplet and a static droplet on a solid surface. The major test variables include height and the relative impact position. The experiment used mirrors to reflect light for taking pictures, from two directions in one frame, for better observation. The results show that:(1) Whether the drops splash or not can still be predicted by Mundo’s (1995) method;(2)The impact will occasionally form a shape like bull horns. The angle between two “horns” decreases with the relative impact distance; (3)The splash pattern varies with impact energy and impact position.
