摘　　要：最大气泡压力法测定溶液表面张力是物理化学实验中的一个传统实验,由于各种因素的影响,导致学生实验结果存在较大偏差。本研究通过浓度、温度等作为变量进行实验条件探索而得到的结果与文献值较为吻合。The maximum bubble pressure method is a classical method to determine the surface tension of solution in physical chemistry laboratory.Due to the influence of various factors,the results from students have large standard deviation.In this study,concentration and temperature were used as variables to explore experimental conditions,and the results obtained were in good agreement with literature values.

关 键 词：最大泡压法 表面张力 条件优化
