摘要
拐点现象的出现,给拉力的取值带来了问题。通过对实验数据和现象的分析,把液膜拉起过程划分为4个阶段,通过分析这4个阶段中拉力变化的原因,从理论上得出取值的最佳时刻。
The inflexion phenomenon in surface tension measurement raises debate on whether the maximum measured force or the force when the surface deform is accurate. In this paper,the liquid surface pulling process is divided into 4 stages,by investigating the pulling force behavior of each stage and analyzes the experimental data,the preferred force value is theoretically expounded.
