Abstract:	垂懸液滴形狀容易受到重力、表面張力、週邊壓力、和接觸物體表面潔淨度等因素所影響。其外形與各因素間的關聯建立在力學定律上。理論上靜態垂懸液滴之一維模式是流體力學上少數具備理論完整性的案例之一，本研究旨在透過簡單液滴外形實測和數理模式分析探討確認液滴外形與其各影響因素間的關聯性和實驗方法的適當性，以便做為探討液滴動態成型問題的基石。 The contour of a pendant drop depends on many factors, such as the cleanliness of the surface it contacts with, drop volume, drop physical and chemical properties, environmental pressure, etc. All these factors can be connected to drop contour via basic laws. The one-dimensional model of a pendant drop is one of the few mathematical models that have solid theory foundation. In this article, using experimental and numerical methods the relationship of drop contour and its influential factors is assured and the validity of drop contour measurement method is investigated. These works lays the foundation for studying the dynamic drop formation problem.
