摘要: 对现有吊环法液体表面张力系数测量仪的水平调节装置、吊环升降装置存在的不足进行了改进,在原有仪器上增加了液体加热装置,以便对不同温度下的液体表面张力系数进行测量,实验说明新的实验装置更加科学合理.通过实验对比得出:新的实验装置操作方便、实验误差小、重复性好,有推广价值.

关键词: 表面张力, 表面张力系数, 吊环法, 改进

Abstract: The present ring method of liquid surface tension,measuring the level of conditioning,shortcoming of the rings lifting devices are improved.The measure of the surface tension coefficient is added in the original instrument for liquid heating the liquid at different temperatures.The new experimental apparatus is more scientific and reasonable,easy to operate. Thus the experimental error is small,reproducible,and has promotional value.

Key words: surface tension, surface tension coefficient, suspension loop law, improvement
