摘要
在枣庄学院所用上海复旦天欣FD-NST-Ⅰ液体表面张力系数测定仪的基础上,改进实验仪的构成,增加温控装置.用改进后的仪器测量了纯净水和皂水表面张力系数随温度的变化关系,测量数据用最小二乘法拟合得到最佳图形,改进的装置为物理实验教学提供参考.
Based at the Zaozhuang University in Shanghai Fudan University FD - NST - I liquid surface tension coefficient measuring instrument, which improved experimental apparatus, increase the temperature control device. Pure water and soap water surface tension coefficient changing with temperature were measured by the improved instrument, measurement data using least squares fitting best graphics, improved device provides the reference for the physics experiment teaching.
