摘　　要：用电子天平测量金属环从水中拉出过程表面张力的变化,对测量结果进行分析修正,明确了用电子天平拉脱法测定表面张力系数的正确计算公式.Variation of the surface tension on the metal loop can be measured by electronic balance when it is drawed off the water,and the surface tension coefficient can be obtained by analyzing the measuring results.The formula for measuring the surface tension coefficient with electronic balance by pulling escape is induced.

关 键 词：表面张力系数 拉脱法 电子天平
