1. It is difficult to use the natural avometer measuring electromotive force engendered by heat in metal cutting, because the avometer cant display accurate value of electromotive force. 用自然热电偶法测量切削温度时，直接用普通万用电表难以准确测出热电动势。
2. The second discussion is that moving induced electromotive force is divided into three types, according to the generating cause of moving induced electromotive force. 第二阐述了依据动生电动势产生的原因，将动生电动势分为三种类型；并且通过实例进行了相关的讨论。
3. Current. electromotive force. or power supplied to an electric circuit. network. or device. 电流。电能。电力：供给电路。网络或设备的电流。电动力量或电力。
4. Phase difference between the terminal voltage of an alternator and its electromotive force. 交流电机的端电压和其电动势之间的相角差。
5. The letter I represents the current in amperes, E the electromotive force in volts, and R the resistance in ohms. 字母I代表电流的安培数，E代表电动势的伏特数，R代表电阻的欧姆数。
