摘　　要：介绍一种测定液体表面张力的自制简易装置,可以测量不同物质、不同浓度液体的表面张力系数。仪器制作取材方便,安装调试简单,尤其是改进了常规液膜"拉脱"方法(焦利秤、扭秤和螺旋升降台),使得自组表面张力系数测试仪精度高,稳定性好。This article introduces a simple instrument measuring liquid surface tension coefficient,which can measure the different substances,different concentrations of liquid surface tension coefficient.The instrument is convenient to manufacture,simple installation and debugging,especially improved the conventional method "pulling escape"(Joly balance,torsion balance,spiral knee).Proved by practice,the accuracy of the surface tension coefficient tester is high,good stability.
