摘　　要：根据对各高等院校电位差计实验的调查 ,作为仪器标定用的化学型标准电池仍然在普遍使用 ,但其在使用、维护及保管中存在很多问题。我们利用现有的电子技术模拟出一种性能可靠、使用维护十分便利的标准电压源 ,以取代化学型标准电池。According to the investigation of the experiment to the difference of electric potential of insttution of higher learning,it is generally being used,yet as standards battery of chemical type that time instrument finalizes the bid,but there are a lot of questions in using maintaining and keeping it,we develop a kind of one reliable practical standard electric potential,it is easy to maintain and use and replace chemical type standards battery.
