摘　　要：用硅压阻式力敏传感器测量了纯水、乙醇的表面张力系数 ,并测量了不同浓度的乙醇水溶液的表面张力系数 ,得到了乙醇水溶液的表面张力系数随浓度的变化曲线 .The surface tension coefficient of water and grain alcohol are measured by using force sensor. The surface tension coefficient of grain alcohol solution with deferent density are also measured. The varying curve of surface tension coefficient and density of grain alcohol solution is obtained.
