摘　　要：电动势的测定是物理化学实验教学中的重要内容,大多数国内高校都开展了关于电动势测定及其应用的实验。但在多年实验管理和教学中发现,实验存在如汞污染严重、甘汞电极损耗较多及实验数据时有不稳定等问题,该文针对上述问题对原电池电动势的测定实验做出几点改进,改进后实验数据更加稳定可靠,同时提高了实验室管理人员的工作效率,节省了实验经费。Measuring electromotance is an important content of physical chemistry experiment teaching. Most of the domestic universities have carried out the experiment of electric potential measurement and the application. But there are some disadvantages and problems existing in this experiment such as mercury pollution, calomel electrode loss and unstable data etc. To resolve these problems the experiment was improved. After improvement the experiment data was more stable and reliable and the working efficiency of laboratory personnel＇s was increased and the experimental expenditure was saved.
