我们闭合线圈，并试着算出线圈内部的电压。
Let's close the loop and let's try to figure out the voltage inside this loop.
在闭合线圈焊接点的制作上，分别采用了超导焊接和普通焊锡焊接两种不同方法。
Two kinds of method were applied in fabricating the joint of the closed coils, one is the superconducting-joint technique and the other is resistive-joint method.
闭合线圈在磁场中运动，线圈中的电流变化将产生自感，自感电流对总感应电流的贡献是不容忽视的。
The current intensity of variations will produce self-induction when a closed coil moves in magnetic field. Must be attended to the contribution of the current by self-induction to total current.
