一则液体表面张力系数测量公式的深层解析

摘要

采用图示法对一则液体表面张力系数测量公式展开了讨论,结果证实了其平衡表达式的正确性.对各参量的物理意义进行了细化分析,发现,理解弹簧的作用原理以及表面张力的表现形式是加深认识该测量公式的关键.%With graphic mothod, discussion was carried out on one formula for liquid surface tension coefficient from three different situation. The results show that the equilibrium expression is correct. Subsequent detailed analysis on the related parameters finds that understanding the working theory of the spring and the behaving process of surface tension is the key factor to comprehend this formula deeply.
