恒流计时法测定离子迁移数及高压恒电流仪研制

DETERMINE THE TRANSFERENCE NUMBERS BY CONSTANTCURRENT AND TIMEKEEPING METHOD AND DEVELOP A HIGH VOLTAGE GALVANOSTAT

应用现代电子技术，自行设计并制成了一种新颖、实用、低价的高压恒电流仪，由此采用一种新方法——自动恒流计时法代替传统的希多夫法来测定溶液中电解质离子迁移数，研究证明整个设计合理合用，测定操作简便。

In this paper, a high voltage galvanostate which is new style, practical, portable and low cost has been designed and developed. By a constantcurrent and timekeeping method which improves the traditional Hittorf method , the transference numbers of electrolytes can be easily determined in CuSO_4 solution.
