该结论不但适用于闭合回路中的感生电动势的计算，而且也适用于有限长导体上的感生电动势的计算。
The conclusion not only can be applied in the calculation of electromotive force of close loop, but also can be applied in the calculation of electromotive force of limited conductor.
By use of the technique of twisted pair wire, the additive EMF in the circuit of the electrode leads has been reduced to 10% of that before use and the precision of the system has been improved.
