摘要
论文采用拉脱法,在室温条件下研究了纯水的液体表面张力系数与金属线框直径的关系,结果表明,液体表面张力系数随金属线框直径的增大而变小。
Surface tension of liquid is an important physical property of liquid,which can be described by the surface tension coefficient.Surface tension of liquid is mainly influenced by temperature,purity,density and variety of liquid.In this work,we studies the relationship between surface tension coefficient and diameter of metal wire frame by the pull-off method at room temperature.The results show that the surface tension coefficient of liquid becomes smaller as diameter of metal wire frame increases.
