摘要

表面张力系数的测量方法有很多，其中拉脱法是简单有效的一种，本实验基于拉脱法通过改变河水泥沙含量、温度进行表面张力系数测量，以探究泥沙含量、温度的变化是否会对液体表面张力系数的测量值造成影响，并对比分析在澄清和悬浊状态下河水表面张力系数的变化情况。通过对实验结果分析可知，液体表面张力测量值与泥沙含量、温度变化有关，河水在悬浊状态下的表面张力系数整体上大于澄清状态下的表面张力系数。

Abstract:

There are many ways to measure surface tension，of which the pull-out method is a simple and effective one．Based on pull-out method，this experiment measures the surface tension coefficient by changing the sediment content and temperature of the river water to explore whether the measured value of the liquid surface tension coefficient will be effected as the sediment content and temperature changes．And the variation of surface tension coefficient of river water in clear and turbidity state is compared and analyzed．According to the analysis of the experimental results，it can be seen that the measured value of liquid surface tension is

related to the change of sediment content and temperature，and the surface tension coefficient of the river water in the turbidity state is generally greater than that in the clear state．

Key words: surface tension coefficient pull-off method force sensor sediment concentration
