【摘要】 物理化学实验教学中多用界面移动法测定H+离子迁移数。但传统的界面移动法存在许多不足,虽然经过多次改进,由于改进不全面和某些细节问题探讨不够,导致实验效果不理想。针对上述问题进行改进,得到实验效果好,实验误差小。能直观、清晰呈现其实验测试原理,且结构简单,操作方便,安全性好。对环境友好的实验装置和与其匹配的实验方法,应用于学生实验教学中,取得满意的教学效果。更多还原

【Abstract】 Moving boundary method was commonly used in Physical Chemistry experiment teaching to determinate H+ ion transference number. However, the traditional method had many deficiencies, which led to unsatisfactory experimental result. In this paper, we improved the methods and devices to solve the existing problems and applied it into the experimental teaching practice.更多还原
