摘要
本实验采用拉脱法测量常温下(25℃)浓度为2%的食盐水溶液、蒸馏水和浓度为0.05%的洗衣粉溶液(以汰渍牌洗衣粉为例)、湖水、海水、自来水的表面张力系数.得出不同浓度、不同温度下的不同液质对表面张力系数的影响.
At room temperature,the pull-out method is used for measuring the surface tension coefficient of the salt water solution with a concentration of 2%,distilled water,detergent solution with a concentration of0.05%（ Tide washing powder）,lake water,sea water and tap water. Obtained are the effects on the surface tension coefficients of different liquids of different concentrations and at different temperatures.
