摘　　要：根据现象迅速而准确地判断出实验故障的原因并排除是实验教学能否顺利进行的根本保证。利用"一看二定三查四排"的方法,针对箱式电位差计测电动势实验中常出现的故障现象,分析了故障原因,提出了解决方法。It is the fundamental guarantee of experimental teaching carrying out successfully that the experimental failures can be found and eliminated rapidly and exactly based on phenomena. With the method of ＂Observe-Confirm-Lookup-Eliminate＂, the causes of failures have been analyzed, and the methods of eliminating failures have been given, for the failure phenomena in the experiment of meas- uring electromotive force with box-type potentiometer.
