摘　　要：通过对水和磁性液体表面张力演示实验的研究,分析了液体表面张力存在的内在因素,使学生对表面张力有更深的认识。水和磁性液体表面张力演示实验的对比研究,为物理实验的课堂演示增加了内容,从现象入手,逐步分析其本质,大大地激发了学生的学习兴趣,并通过对磁性液体表面张力的研究,为磁性液体在润滑、密封等领域的应用提供一些启示。The demonstrative experiment of surface tension about water and magnetic fluid was researched, and the intrinsic factor of surface tension＇ s existence was analyzed in order to understand surface tension deeply. By the comparative study of water and magnetic fluid, the contents of classroom demonstration in physical experiment were increased. The learning interest of students was excited effectively by viewing experimental phenomenon and construing phenomenal hypostasis. The study offered inspiration for magnetic fluid＇ s application in the area of lubrication and sealing.
