摘　　要：通过选取含支链碳氟结构的表面活性剂进行研究，在水中加入表面活性剂，使水表面张力降低，配置成多种浓度的试液，用表面张力仪测量在不同浓度下的表面张力，同时使用分离器测量不同浓度下的泡沫量，记录数据，绘制成图形。通过数据分析可知：发泡性能与降低表面张力的能力大小成正比，表面张力减小，对泡沫形成有利；各活性剂测得的最小张力值，最大发泡量均出现在浓度为0．001—0．004mol／L之间；FC一1、壬基钠在降低表面张力与发泡能力方面性能最佳。By selecting a branched fluorocarbon surfactant structure research in the water by adding a surfactant, the surface tension of the water was reduced, the concentration of the test solution into a variety of configurations, the surface tension was measured at different concentrations on the surface tension measurement while using different concentrations of the separator and the bubble quantity of recording data graphed. Data analysis showed that foaming properties and the ability to reduce surface tension proportional had a linear relationship, the reduced surface tension enabled the bubble formation, the minimum tension value measured, the maximum expansion volume was between the concentration of 0. 001 mol/L to 0. 004 mol/L, and FC - 1 and sodium nonyl could reduce the surface tension and foaming ability, which was the best.
