摘　　要：在高二“铜-锌双液原电池”的教学实践中,针对教材中使用“饱和KCl溶液-琼脂盐桥”存在诸多问题,尝试用浸泡了饱和KCl溶液的鹿皮巾制成鹿皮巾盐桥,并用其代替“饱和KCl溶液-琼脂盐桥”进行了实验。结果表明:鹿皮巾盐桥具有“装置简单、操作简便、反应迅速、现象明显”等优点,有一定的推广价值。In the teaching practice of“copper-zinc double-liquid primary cell”in second year of high school,there were many problems with using“saturated KCl solution-agar salt bridge”in textbooks.Therefore,the deerskin towel salt bridge made of deerskin towel soaked in saturated potassium chloride solution was used in this paper to try to replace the“saturated KCl solution-agar salt bridge”for the experiment.The results showed that the deerskin towel salt bridge had the advantages of simple device,easy operation,rapid reaction,obvious phenomena,etc.,and had certain value to be promoted.
