摘要
测量金属薄片从液体中拉出过程中液膜高度和拉力的关系,分析其产生的原因,给出液体表面张力系数的准确测量方案.
The relation between height of the liquid film and the tensile force in the process of metals thin slice to pull up the liquid film is measured. The reason of its creation is analyzed and a project about the liquid surface tension coefficient of accurate measure is given.
