最大气泡压力法测定溶液表面张力实验的优化设计

Comprehensive Improvement of Surface Tension Measurement by Bubble Maximum Pressure Method

从测试溶液类型、实验数据的处理方法两方面对最大气泡压力法测定表面张力实验做出改进。改进后的实验将促使学生更深入地全面掌握溶液表面的性质如吸附现象、吸附量和表面活性剂的临界胶束浓度等,学生能够从本实验中获得知识最大化,拓展学生实验思路。此外,采用origin软件处理实验数据,有助于提高学生处理实验数据的能力,提高学生实验综合能力。

The comprehensive improvement was provided for the determination of surface tension experiment based on the select of solution types to be tested and the processing methods of experiment data.It would help students understand thoroughly the surface adsorption phenomenon of solution,adsorption capacity and surfactant critical micelle concentration.By this experiment,students could gain the maximize knowledge,and enhance the research ability of students.Compared with the surface tension program,the processing method of experimental data using origin software would enhance the ability of students to process data,and improve the comprehensive scientific research ability of students.
