Abstract:	本文研究主旨是利用磁性流體液滴形狀測量接觸角時，液滴影像的品質及分析液滴形狀的程式決定了接觸角。利用分析程式從液滴邊界偵測及液滴形狀分析找出接觸角。再藉由外加磁場的改變，觀察磁性流體液滴與試管接觸角的變化。最後利用Matlab程式以梯度法找出符合真實影像的液滴邊界，利用液滴形狀分析得出接觸角。去比較磁性流體受到磁場大小之變化。 Research thrust of this article is the contact angle using magnetic fluid droplet shape measurement，droplet image quality and analysis droplet shape the program decided to contact angle。Analysis program from the droplet boundary detection and droplet shape analysis to identify contact angle。Then observed by the change applied magnetic field, magnetic fluid droplets and in in external magnetic field change change of contact angle，Last using Matlab program to meet real image of the droplet boundary gradient method ，use drop shape analysis derived contact angle， compare the magnetic fluid by magnetic field changes size 。
