摘要
表面张力在物理学中是一个重要的物理量。由于液体表面张力的大小取决于液体表面张力系数,所以测量液体表面张力系数具有重要意义。本文分别采用拉脱法、U型管法和水波频闪法,对在20℃条件下纯水表面张力系数展开测量。文中给出了相关实验原理和测量结果。误差分析结果表明,U型管法测量相对误差最小,测量精度最高。
The surface tension of liquid is a very important mechanical parameter in physics. The study on the liquid surface tension coefficient is very important, since the liquid surface tension depend on its quantity. In this paper, some measuring methods for tension coefficient of the liquid surface, including the pulling escape, U - tube and water stroboscopic methods, have been introduced, respectively. Also, the experimental results are presented.
